revised form 23March 2007;accepted 23March 2007Editor:R.D.van der HilstAvailable online 31March 2007AbstractThe closed inland Qaidam Basin in the NE Tibetan Plateau contains possibly the world's thickest (∼12,000m)continuous sequence of Cenozoic fluviolacustrine sedimentary rocks.This sequence contains considerable information on the history of Tibetan uplift and associated climatic change.However,work within Qaidam Basin has been held back by a paucity of precise time constraints on this sequence.Here we report on a detailed paleomagnetic study of the well exposed 4570m Huaitoutala section along the Keluke anticline in the northeastern Qaidam Basin,where three distinct faunas were recovered and identified from the middle Miocene through Pliocene.Constrained by these faunal ages,the observed thirty-three pairs of normal and reversed polarity zones can be readily correlated with chrons 2n-5Br of the GPTS.This study assigns the age of the section to the interval between ca.15.7Ma to 1.8Ma.In addition,the widely used stratigraphic units the Xia Youshashan,Shang Youshashan,the Shizigou and Qigequan Formations were formed at N 15.3Ma,15.3–8.1Ma,8.1–2.5Ma and b 2.5Ma,respectively.We obtained a very high average sedimentation rate of ∼33cm/ka over the entire interval 15.7to 1.8Ma.Furthermore,the average sedimentation rate is punctuated by three intervals of persistent rapid increases starting at about ∼14.7Ma,8.1Ma and 3.6Ma.These intervals are interpreted as times of rapid uplift and fast exhumation of the NE Tibetan Plateau.©2007Published by Elsevier

(X.Fang).0012-821X/$-see front matter ©2007Published by Elsevier B.V .doi:10.1016/j.epsl.2007.03.0421.IntroductionThe Qaidam Basin (∼850km long ×150–300km wide =∼121,000km 2)is the largest basin on the north-eastern Tibetan Plateau.It is bounded by the Qiman Tagh –Kunlun Shan (Mts.)to the south,the Altyn Tagh (Mts.)to the northwest,the Qilian Shan (Mts.)to the northeast and the Ela Shan (Mts.)to the east.It has an average elevation of 3000m above sea level,in contrast to the surrounding mountains with elevations of 4000–5000m (Fig.1).It has been interpreted to have been a closed inland basin since the Paleocene and is filled with a maximum thickness of ∼12,000m of Cenozoic sedi-ments (the thickest known section of Cenozoic continent sediments)shed from the surrounding mountains [1–3].It is located in the arid region of North China,but is still affected by the front of the Asian monsoon.The sedimentary record of this basin attracts considerable attention because:(1)it contains a great potential record of the initiation and development of the Asian monsoon and of Asian aridification [4–6];(2)it provides a record of the ongoing growth of the Tibetan Plateau flat surface through the infilling of basins [7,8];(3)it provides a typical example for Cenozoic crustal detachment [9,10];and (4)it provides a record of the deformation and uplift of the Kunlun Shan and the Qilian Shan,especially the activation of the huge (1500m long)strike –slip Altyn Tagh fault that has been thought to be a key boundary to transfer the deformation caused by the collision of India with Asia by continental extrusion [8,11,12].Several tectonic models predict that either the Qaidam Basin and the northeastern Tibetan Plateau are the most recently deformed and most tectonically active part of Tibet [7,8,10],or comprise the entirety of the Cenozoic deformed block [13].Unfortunately,until our work,we have not had accurate chronology and paleoenviron-mental and tectonic records from the Qaidam Basin to either to reconstruct the histories of the Asian monsoon and Asian desertification,or for testing the tectonic models.This lack of an accurate chronology is largely caused by a previous paucity of mammalian fossils or other means of obtaining geochronology from the thick Cenozoic sedimentary sequences.This barrier was slowly breached by a steady stream of discoveries of fossil mammals in the east Qaidam Basin since 1998[14,15]that followed earlydiscoveriesFig.1.DEM presentation of the geomorphology of the Qaidam Basin and its surrounding mountains.1:Honggouzi anticline;Thrust belt:North Qaidam marginal thrust belt.294X.Fang et al./Earth and Planetary Science Letters 258(2007)293–306by a Swedish paleontologist,Birger Bohlin.With fewexceptions,the mammal sites are located in thenortheastern Qaidam Basin in the vicinity of Delinghaand Huaitoutala and span the stratigraphic interval be-tween the middle Miocene and Pliocene[16,17](Fig.8).We now have sufficient mammal finds that are agediagnostic to provide chronological constraints on anumber of fossiliferous sections.Encouraged by thesefindings,we choose the Huaitoutala section,10km southof the village of Huaitoutala,for detailed paleomagneticstudies,because it bears seven layers of fossil mammalscontaining components of most of the fossil mammalgroups found in the region(Fig.2).A chronology basedon an integrated study of the mammalian fossils andpaleomagnetic polarity reversals obtained from the rel-atively long and continuous section offers the best reso-lution possible for a continental setting that does notcontain volcanic rocks that can be radiometrically dated.The absence of dateable volcanic rocks is typical ofmuch of Asia during the Cenozoic[16].2.Geologic setting and stratigraphyThe high relief contrast between the depressedQaidam Basin and highly uplifted surrounding moun-tains is controlled by the large boundary faults betweenthem[1,2,11,12](Fig.1).The north Kunlun fault,derived from the Kunlun fault belt along the QimanTagh and the Kunlun Shan,bounds the southern marginof the Qaidam Basin.The Kunlun fault runs roughlyeast–west for about1100km and is a major strike–slipfault thought to absorb and transfer deformation im-posed by the collision of India with Asia[11,12](Fig.1).The impressive1500-km long,NE–SW left-lateral strike–slip Altyn Tagh fault cuts through thenorthwestern margin of the Qaidam Basin.Between ∼350–400km[18–20]and∼500–700km displace-ment[21,22]is thought to have taken place along thefault.This displacement has caused not only the depres-sion and deformation of the Qaidam Basin and formationof the Altyn Tagh mountains,but has also transferredmuch of the deformation into the broad region of the NanShan–Qilian Shan,resulting in an intense uplift of theregion[2,8,11–13,23](Fig.1).The northern margin ofthe Qaidam Basin is bounded by the Nan Shan and theZongwulong Shan faults(also called the south marginalfault of Qilian Shan;F1in Figs.2and3)that run in aNWW–SEE direction.These faults are not only geo-metrically but also dynamically linked with the AltynTagh fault to absorb the transferred deformation andhave caused strong deformation and uplift of the NanShan.This transfer has formed a broad thrust belt(ca.440km long×65km wide=30,000km2)in the northernmargin of the Qaidam Basin,called the north Qaidammarginal thrust belt(NQMTB),which parallels thesouthern margin of the Qilian Shan[1,2](Fig.1).Aseries of north-dipping thrusts and their associated south-dipping backthrusts can be clearly observed in the sur-face,satellite and DEM images and seismic profileswithin the NQMTB in the study area.These thrusts andbackthrusts fall roughly into four groups of tectonicunits,the Delingha depression,the Olonbuluk upheaval,the South Olonbuluk depression,and the Emonike up-heaval(Figs.1–3).To the north and south of theNQMTB are the tectonic units of the Qilian Shan and thePlio-Quaternary depocenter of the Qaidam Basin,theHuobusun depression with a maximum depth of ∼12,000m[1,2].The Emonike upheaval is the front of the north Qaidam thrust belt,and exposes largelyDevonian volcanic detritus and sea shelf limestone withsome Carboniferous sandstone and limestone and Ju-rassic sandstone and mudstone with coals(Fig.2).Fieldobservations and seismic data show that the backthrustsF4and F3of front thrust F7have caused a south tilteddepression,the south Olonbuluk depression.The long-axis of the depression deepens southwestwards with amaximum depth of3500–400m occurring in the area ofthe Tuxi to Wulan anticlines to the southeast of Tuosu Hu(Lake)(Figs.2and3).These data further show that theOlonbuluk upheaval is a thin bedrock slab that wasprobably also uplifted by the larger backthrust F2of frontthrust F7.This fault backthrusts the southern margin ofthe Delingha depression northward,to face the oppositethrust fault F1that thrusts the northern margin of theDelingha depression southward.This tectonic activityhas probably given rise to the formation of the very deepNWW–SEE trending Delingha depression(∼3687km2)that contains Cenozoic sediments that are over6000mthick(Figs.2and3).Furthermore,the strong back-thrusting of F2has caused the backward propagationfault F2that thrusts and folds the Cenozoic stratigraphyto the north of the Olonbuluk Shan to form the Kelukeanticline(Figs.2and3).The Cenozoic stratigraphy in the Qaidam Basin hashistorically been divided into six formations with as-signed ages.These are(in upward sequence)the LuleheFm.(Paleocene to Eocene,E1–2),the Xia GanchaigouFm.(Oligocene,E3),the Shang Ganchaigou Fm.(earlyMiocene,N1),the Xia Youshashan Fm.(mid Miocene,N21),the Shang Youshashan Fm.(late Miocene,N22),theShizigou Fm.(Pliocene,N23)and the Qigequan Fm.(early Pleistocene,Q1).This age assignment is largelybased on pollen and ostracode analyses and has beenwidely accepted for geologic and tectonic studies and295X.Fang et al./Earth and Planetary Science Letters258(2007)293–306F i g .2.G e o l o g i c m a p o f t h e e a s t e r n p a r t o f t h e n o r t h Q a i d a m m a r g i n a l t

the margins of the Qiman Tagh –Kunlun Shan,the Altyn Tagh and the Nan Shan.The lithology is predominant-ly purple red and dark red alluvial conglomerate and gravelly sandstone intercalated with some sandy mud-stone and siltstone along the basin margin and a distal facies of shallow lake siltstone and mudstone toward the basin center.It superimposes unconformably upon Early Cretaceous and other older rocks.The Xia Ganchaigou Fm.has a larger distribution area than the Lulehe Fm.and is characterized by alternate brown red alluvial to fluvial conglomerate,gravelly sandstone and brown,yellow-green sandy mudstone in the lower part and playa brown siltstone and gray mudstone in the up-per part with thick salt and gypsum deposits in the depocenter close to the Altyn Tagh fault.The Shang Ganchaigou Fm.covers the whole basin and is largely interbedded multi-colored (brown to gray-green)lacus-trine sandstone,siltstone and mudstone intercalated with marl and nodular limestone.The Xia Youshashan Fm.appears over the entire basin and consists largely of gray yellow and brown sandstone to mudstone with some oolite marl at the basin center and fine conglomerate and sandstone at the basin margin.The Shang Youshashan Fm.is dominated by gray/yellow-green and light brown conglomerate,gravelly sandstone,siltstone and mud-stone.It contacts conformably with the underlying Xia Youshashan Fm.at the basin center but unconform-ably at the basin margins,especially along the western margin.The Shizigou Fm.is mostly conglomerate to sandstone intercalated with

Fm.,Shizigou Fm.and Qigequan Fm.(Fig.3).The Xia Youshashan Fm.has an exposure of only100m,characterized by fine-grained sedi-mentary rocks of siltstone,mudstone and marl.The Shang Youshashan Fm.is2250m thick(from100m to 2350m)and consists mainly of conglomerate and sandstone intercalated with siltstone for most of the stratigraphy and siltstone and mudstone in the upper-most part.The Shizigou Fm.is1750m thick(from 2350m to4100m),and is dominated by thick sand-stone intercalated with some mudstone.The Qigequan Fm.is only470m thick and is mainly conglomerate intercalated with thin sandy siltstone and mudstone (Fig.8a).3.Sampling and measurementsOriented block samples of roughly10×10×8cm were taken at intervals of2–5m depending on the availability of a suitable lithology at each level(site). These block samples were then cut into three oriented cubic specimens of2×2×2cm in the laboratory to form three parallel sets of samples for cross-calibration mea-surements.A total of1650block samples and1650×3 specimens were obtained.Systematic stepwise thermal demagnetizations(in fifteen to twenty discrete steps between∼25°C and 690°C at intervals of50°C below550°C and10–20°C above it)were done on the first set of specimens and the240pilot samples of the second set of the speci-mens.Remanent intensities and directional measure-ments were done on a2G Enterprises magnetometer in a magnetically shielded room,first in the Paleomag-netism Laboratory of the Institute of Geology and Geophysics(Chinese Academy of Sciences)and the Paleomagnetic and Rock Magnetic Laboratory of the Key Laboratory of Western China'sEnvironmentalSystems (Ministry of Education of China)in Lanzhou University,and then at the Graduate School of Ocean-ography,University of Rhode Island.Based on these results,only six to eight steps for temperatures between 350°C and 675°C were applied to the remaining specimens of the second set.The intensity of the natural remanent magnetization (NRM)of the clastic sedimentary samples is 1.5×10−2to 1.6×10−3A/m for mudstone and siltstone,and 0.6×10−2to 0.8×10−3A/m for sandstone.Representa-tive thermal demagnetization diagrams are shown in Fig.4.Most samples show simple demagnetization behavior.Below 50–100°C,a viscous remanent mag-netization (VRM)is readily removed (Fig.4).Between 100and 120°C,many samples show a clear decrease in magnetization ,accompanied by a clear change of rem-anent direction that indicates the removal of a second-ary remanent magnetization (SRM)stored by goethite (Fig.4a,b,c).Most samples show a low unblocking temperature component that can be removed easily at 250°C (Fig.4).Above this temperature,a characteristic magnetization (ChRM)is clearly isolated and decays nearly linearly to the origin.Three obvious rapid decays of the magnetization were observed for most samples at about 350°C,580°C and 660–690°C,indicative of the presence of maghemite,magnetite and hematite that act as major ChRM-carriers (Fig.4).ChRM component directions have been calculated for all samples using Principal Component Analysis.Rem-anence directions of the specimens generally agreed between the three laboratories unless the specimens were unstable and showed noisy demagnetization behavior (∼10%of the total,mostly from coarse sandstones).The final ChRM direction at each site was obtained by Fisher averaging of the directions from the two sets of spec-imens.Specimens not included in our magnetostrati-graphic analysis were rejected based on three criteria.(1)ChRM directions could not be determined because of ambiguous or noisy orthogonal demagnetization dia-grams.(2)ChRM directions revealed maximum angular deviation (MAD)angles greater than 15°.(3)Speci-mens revealed magnetizations with virtual geomagnetic pole (VGP)latitude values less than 30°.A total of 495horizontal levels in the column (30%)were excluded.The final remanent directions are averaged for each level and then are used to calculate VGPs that are plotted as a function of thickness after various paleomagnetic tests (Figs.5–7).Fig.5.(a)Equal-area projections of the characteristic remanent magnetization (ChRM)directions and mean directions

Planetary Science Letters 258(2007)293–3064.MagnetostratigraphyAll the accepted ChRM directions of the Huaitoutala section from the Keluke anticline are used for a reversal test after tilt correction.An equal area projection of these ChRM directions shows that they record signals from the dipole of the earth's magnetic field(Fig.5a).A statistical bootstrap technique[25]has been used to test whether the distributions of the ChRM vectors are possibly non-Fisherian,and to characterize the associ-ated uncertainties for both normal and reversed ChRM directions(Fig.5b).The histograms of the Cartesian coordinates of bootstrapped means[25]allow us to determine a95%level of confidence(ovals around the means in Fig.5a)and to demonstrate that the bootstrap reversal test is positive(Fig.5b).The large change in bedding tilt along the section nearly orthogonally transecting the north limb of the Keluke anticline(Fig.3)provides an opportunity for a fold test[26,27].248representative high quality (MAD b5)site-mean ChRMs from different parts of the section were used for a calculation by the method of McElhinny[26],which indicates a positive fold test with the tilt-dependent dispersed ChRM directions tending to cluster together around their antipolar means(Fig.6).Furthermore,a jackknife technique[28]was used to quantify the reliability of the magnetostratigraphy.The jackknife parameter(J)obtained for the accepted spec-imen-mean directions has a value of−0.3,which falls within the range of0to−0.5recommended for a robust magnetostratigraphic data set by Tauxe and Gallet[28]. This result indicates that sampling of the section has recovered more than95%of the true number of polarity intervals(Fig.7).Fig.8shows a thickness vs.VGP plot of all the accepted and tested ChRM directions.It shows that there are a total of33normal and33reversed polarity intervals recorded in the Huaitoutala section,marked as N1–N33 and R1–R33,respectively(Fig.8).The observed po-larities can be correlated well with chrons2n-5Br of the Geomagnetic Polarity Time Scale(GPTS)of Cande and Kent[29]for most of the section.First,the strikingly long normal intervals N3–N4,N18and N29–31can be readily correlated to the characteristic longnormal Fig.6.Diagram showing a positive fold test of the248representative high quality site-mean ChRMs from different parts of the section using method by McElhinny[26].(For interpretation of the references to colour in this figure legend,the reader is referred to the web version of this article.) 300X.Fang et al./Earth and Planetary Science Letters258(2007)293–306chrons 2n (the Gauss Normal Polarity Chron),5n and 5ACn-5ADn,respectively.Then,the short normal inter-vals N5–N8of nearly equal duration are straightfor-wardly correlated to the four short normal events of chron 3n in the Gilbert Reversed Polarity Chron,as the Cochiti,Nunivak,Sidufjall and Thvera subchrons,respectively (Cande and Kent [29]);N9–10to chron 3An;N13–14,N16,N21–22,N27–28and N32–33to chron 4n,4An,5An,5ABn and 5ABn,respectively (Fig.8).The two clearly normal intervals N1and N2at the top of the section are regarded as analogs of the Reunion and Olduvai subchrons (2r.1n and 2n)in the Matuyama Reversed Polarity Chron,because of the persistent occurrence of very coarse sedimentary rocks (conglomerate and coarse sandstone)that indicate a fast depositional rate (Fig.8).Thus,the whole section was estimated to have formed between about 15.7Ma and 1.8Ma.The fossil mammals found in the lower,middle and upper parts of the section provide robust constraints on our interpretation of the observed polarities.These mammals fall into three faunas in the middle Miocene,late Miocene,and early Pliocene,respectively (Wang et al.,in preparation)(Table 1and Fig.8b).The Olonbuluk Fauna contains species of primitive deer Lagomeryx and Stephanocemas ,as well as rhinos such as Acerorhinus tsaidamensis [15].These taxacommonly occur in the middle Miocene of north China and are typical elements of the Tunggurian Land Mammal Age [30].The Tuosu Fauna features possibly the earliest occurrence of a Hipparion horse [16],as well as left over elements from the middle Miocene such as the Dicroceros deer.Presence of the three-toed horse undoubtedly indicates a late Miocene age and the Tuosu Fauna thus falls in the Baodean Land Mam-mal Age.The Huaitoutala Fauna currently contains small mammals only.It contains such typical Pliocene north China components as Orientalomys/Chardi-nomys and Mimomys and belongs to the Yushean Land Mammal Age.Thus defined,the lower Olonbu-luk Fauna is estimated to occur in 12.5–13.8Ma,the middle Tuosu Fauna at ∼11.4–9.5Ma,and the upper Huaitoutala fauna at ∼4.8Ma (Fig.8).Fig.9presents a thickness-vs.-age plot of the main chrons.It shows a linear relationship between the sam-pling thicknesses and chron ages that agrees to a first order (long-term change)with the lithologic change,which lends further support to our interpretation.Thus,the complete Shang Youshashan Fm.and Shizigou Fm.are determined to have formed in the intervals 15.3–8.1Ma and 8.1–2.5Ma,respectively.The Xia Youshashan Fm.and Qigequan Fm.are older and younger than 15.3Ma and 2.5Ma,respectively.5.Tectonic implicationsBased on the magnetostratigraphy,the average sedi-mentation rate of the Huaitoutala section was calculat-ed at about 33cm/ka.This very high rate is punctuated by three large persistent increases that started at about 14.7Ma,8.1Ma and 3.6Ma.We interpret these un-usually high sedimentation rate changes as records of three episodes of rapid tectonic uplift and fast exhu-mation and denudation (events T1to T3)of the NE Tibetan Plateau for the following reasons (Fig.9).First,early Cenozoic sedimentation rates are estimated at about 4–8cm/ka in the Qaidam Basin and the Tarim and Hexi Corridor Basins to the west and north of the Qilian Shan [31–33],and as low as ∼2–3cm/ka in the Xining Basin in the eastern Qilian Shan and Lanzhou –Linxia Basins [34–37](see Fig.1for localities).Sec-ond,in the late Cenozoic,sedimentation rates in these areas are generally three to four times higher than the early Cenozoic [33,36,38,39]with maximum rates over 70–80cm/ka clearly associated with tectonic defor-mation and uplift in the Gonghe –Guide Basin and Tarim Basin [40,41](Fig.1).Third,the late Cenozoic sedimentation rate increase also broadly agrees with the tectonic evolution of a late rapid deformation andupliftFig.7.Magnetostratigraphic jackknife analysis (Tauxe and Gallet [28])for the Huaitoutala section.The plot indicates the relationship between average percent of polarity zones retained and the percentage of sam-pling sites deleted,where the slope J is directly related to the robustness of the results.The obtained slopes J have values of −0.3032in the study section,which predicts that the section has recovered more than 95%of the true number of polarity intervals.301X.Fang et al./Earth and Planetary Science Letters 258(2007)293–306Fig.8.Magnetostratigraphic results versus lithostratigraphic position for the Huaitoutala section.Sites and main components of fossil mammals found along the section are plotted on the right side of the stratigraphic column for general age constraint.Identification of the mammals and their significance will be

thermochronology[3,7,8,10,13,18,23,36,41–45].Specific evidence for event T1includes field obser-vations of the Honggouzi anticline in the northwest Qaidam Basin(Fig.1)and seismostratigraphy of the Qaidam Basin demonstrate quite clearly that an uncon-formity occurs between the Shang Youshashan and Xia Youshashan Fms.close to the south slope of the Altyn Tagh and north margin of the Qaidam Basin.In our section,the first increase of sedimentation rate is also at the boundary of the Shang Youshashan and Xia Youshashan Fms.at15.3Ma accompanied by sharp changes in lithology from mostly fine sedimentary rocks of calcareous siltstone,mudstone and marl to predom-inantly coarse sedimentary rocks of sandstone interca-lated with conglomerate(Figs.8and9).In addition, rapid cooling of the rocks due to fast exhumation of the Qilian Shan and rapid rotation of the Guide Basin just east of the Qaidam Basin are recorded since the mid Miocene[46,47].Specific evidence for event T2at∼8.1Ma starts at the bottom of the Shizigou Fm.and is characterized by an upward increase of thick sandstone in the section (Fig.8),and of conglomerate in other sections over the margin of the Qaidam Basin.The predominance of alternating conglomerate and sandstone is the most marked feature of the Shizigou Fm.in the basin,and is indicative of rapid uplift of the surrounding moun-tains[1,2].A number of tectonic deformation and uplift events at∼8Ma have been reported around the Qaidam Basin and from various parts of the Tibetan Plateau,e.g.the Guide and Linxia Basins for the uplift of the east Kunlun Shan and west Qin Ling(Mts.) [36,41](see Fig.1for locations);the Jiuquan Basin in the west Hexi Corridor for the uplift of the north Qilian Shan[44,48];the Altyn Tagh from thermochronology [43,45];the Kuche depression for uplift of the Tien Shan[33];the Longmen Shan for uplift of east Tibet [49,50];and the Yangbajing Basin for uplift of south Tibet[51].The third sedimentation rate increase(event T3) at3.6Ma is not accompanied by a sharp lithologic change in the study section(even though the Quater-nary section is completely dominated by conglom-erate)(Figs.8and9),but is synchronous with the occurrence of a growing stratum dipping from67°to 45°within a narrow interval.This stratum is clearly indicative of a synchronous folding of the Keluke anticline by a backward propagation fault F2from backthrust F2due to a push by the southern Qilian Shan (Figs.1and3).Seismostratigraphy confirms that this growth stratum is an overall feature around all margins of the Qaidam Basin[1,2].An eastward fast shift of the depocenter of the Qaidam Basin was estimated to occur largely since the Plio-Quaternary[1,2,42].Just to the north side of the Qilian Shan,an unconformity caused by the strong deformation from the Qilian Shan was paleomagnetically dated at∼3.7Ma[44].Huge and thick boulder conglomerate due to a tectonic uplift first appeared at about this time around the rim of the whole Tibetan Plateau[38,41,44,48,52,53],although a con-current climatic change may also have contributed to this abrupt change[54].Initiation of an E–W extension and graben system in northern Tibet and the formation of the Kunlun Pass Basin due to the strike–slip of the Kunlun fault and other strike–slip faults,and the basaltic eruption and fast cooling of granites on the eastern Tibetan Plateau due to rapid tectonic uplift and exhumation are all reported to occur at about this time [48,55–58].The end of sedimentation in the study section at about1.8Ma is regarded as the strongest tectonic deformation due to the fast backward propagation of F2 driven by rapid backthrusting of F2,leading to the formation of the Keluke fault-propagation anticline. This anticline seems to be forming a clear step cutting the north limb of the anticline to the present.This fastTable1Mammalian faunas found in the Huaitoutala magnetic section and the nearby Tuosu Nor sectionName of fauna and component Suggested age Olongbuluk Fauna Middle Miocene(12–15Ma) Acerorhinus tsaidamensis,CD9825Lagomeryx tsaidamensis,CD9811,CD9818Stephanocemas sp.,CD9818Tuosu Fauna Late Miocene(10–12Ma) Dicroceros sp.,CD9815Euprox sp.,CD9820?Qurliknoria sp.,CD9824Chalicotherium brevirostris,CD9823Cervidae indet.,CD9824Artiodactyla indet.,CD9816Proboscidea indet.,CD9816Huaitoutala Fauna Early Pliocene(4–5Ma) Mimomys sp.,CD9822Orientalomys/Chardinomys sp.,CD9822Micromys sp.,CD9822Pseudomeriones sp.,CD9822Soricidae indet.,CD9822Numbers following taxonomic names are field numbers of the Institute of Vertebrate Paleontology and Paleoanthropology.For a more complete faunal list that includes mammals from other sections,see Wang et al.(in review).。

2007年全国大学生数学建模竞赛A题优秀论文—人口预测模型

中国人口预测模型摘要本文对人口预测的数学模型进行了研究。

首先,建立一次线性回归模型,灰色序列预测模型和逻辑斯蒂模型。

考虑到三种模型均具有各自的局限性,又用加权法建立了熵权组合模型,并给出了使预测误差最小的三个预测模型的加权系数,用该模型对人口数量进行预测,得到的结果如下:其次,建立Leslie人口模型,充分反映了生育率、死亡率、年龄结构、男女比例等影响人口增长的因素,并利用以1年为分组长度方式和以5年为负指数函数,并给出了反映城乡人口迁移的人口转移向量。

最后我们BP神经网络模型检验以上模型的正确性关键字:一次线性回归灰色序列预测逻辑斯蒂模型Leslie人口模型BP神经网络一、问题重述1. 背景人口增长预测是随着社会经济发展而提出来的。

在过去的几千年里,由于人类社会生产力水平低,生产发展缓慢,人口变动和增长也不明显,生产自给自足或进行简单的以货易货,因而对未来人口发展变化的研究并不重要,根本不用进行人口增长预测。

而当今社会,经济发展迅速,生产力达到空前水平,这时的生产不仅为了满足个人需求,还要面向社会的需求,所以必须了解供求关系的未来趋势。

而人口增长预测是对未来进行预测的各环节中的一个重要方面。

准确地预测未来人口的发展趋势,制定合理的人口规划和人口布局方案具有重大的理论意义和实用意义。

2. 问题人口增长预测有短期、中期、长期预测之分,而各个国家和地区要根据实际情况进行短期、中期、长期的人口预测。

例如,中国人口预期寿命约为70岁左右,因此,长期人口预测最好预测到70年以后,中期40—50年,短期可以是5年、10年或20年。

根据2007年初发布的《国家人口发展战略研究报告》(附录一)及《中国人口年鉴》收集的数据(附录二),再结合中国的国情特点,如老龄化进程加速,人口性别比升高,乡村人口城镇化等因素,建立合理的关于中国人口增长的数学模型,并利用此模型对中国人口增长的中短期和长期趋势做出预测,同时指出此模型的合理性和局限性。

如何有效帮助单亲家庭中的问题学生健康成长姓名:焦金欢学校:县一小近几年,随着社会中离婚率的逐年攀高,单亲家庭数量的上升,单亲家庭子女的教育问题已经成了一个社会问题,父母的离异,让很多孩子承担了原不该属于自己这个年龄的痛苦。

诸多单亲孩子内心的伤痛,给社会带来了新的问题,也给我们教育工作者带来了许多困难。

由于这些孩子处在一个特殊的家庭结构里,他们在思想、学习、性格,甚至健康方面在一定程度上都有别于完整家庭的子女,具有一定的特殊性。

如何认识这种特殊性,怎样有针对性地对单亲家庭的学生进行教育,不仅许多单亲家庭的父母对此茫然失措,学校也是“老兵遇着新问题”,社会目前也缺乏有效的特别是有针对性的指导。

所以在这个时候,我对“如何有效帮助单亲家庭中的问题学生健康成长”这个问题进行了进一步的探究。

希望通过个案的研究找到单亲家庭学生的一些特殊的共性,给予单亲家庭的父母一些有规律的方法,对孩子进行行之有效的指导,从而让他们健康的成长。

作为辅导员,我主要针对“形成单亲家庭问题学生的原因,以及如何帮助这些孩子抚平心理创伤。

”做些有目的的探索,主要是争取把健康的家庭教育的理念、家庭教育方法以及教育孩子成长的有效途径渗透给家长,走出由于父母离异给自己带来的心灵困惑,和同龄孩子一样,用健康的心态去迎接学习、生活的新挑战。

通过对单亲家庭中的问题学生的调查研究、探索总结,我对“如何有效帮助单亲家庭中的问题学生健康成长”,也有了一些小小的收获。

一.用爱心去弥补受伤的心灵。

单亲家庭的孩子在家庭遇到变故时,往往心灵受伤,从而关闭与同学、老师交流的窗户。

爱是打开他们心扉的钥匙,是缝合心灵创伤的灵丹妙药。

我从他们忧郁的眼神里,看到了一颗受伤的心,一颗渴望家庭温暖的心,一颗渴望大家关爱的心。

老师和同学都关心他们,愿意帮助他们。

精诚所致,金石为开”。

在老师,同学,校领导的关爱下,他们最终会走出心灵的阴影,露出了盈盈笑脸。

二不断鼓励与表扬去增强自信。

Abstract
The classical methods for model building are usually based on the parameters selection for xed model form. In this paper, we use a method based on natural genetic evolution for a practical problem in engineering geologics. Several useful and interpretable models are obtained in some runs. It is e cient for the prediction and decision in searching the optimal model .
2 Evolutionary Model-Building
To build a model means to provide a convenient conceptual representation of the observed system from examples. It is on the model which we use to think about the true situation that interpretations, predictions, and decisions would be based. The quality of a model is measured by an objective function , which is related to the discrepancy of the observed values fyi g from the expected values ff (xi )g and is normally induced by a distance function 4] . Genetic algorithms ( GAs ) , rst speci ed by John Holland in the early seventies, are becoming an important tool in optimization problems and machine learning. GAs are adaptive search strategies based on a highly abstract model of biological evolution. Coding techniques and selection mechanisms are two major parts in a GA. Population size is an important parameter to consider when applying a GA to a particular problem. Compare with the classical optimal algorithms, GAs have several speci c characters. A GA deals with codes of individuals, not the individuals themselves. A GA maintains a population of individuals, not an individual one time. A GA uses much less auxiliary information for tness than classical methods and it probabilistically modi es the population by some genetic operators. The four fundamental steps in a GA are as following: To determine a representation scheme, To determine a measure for tness, To determine the parameters and variables to control the algorithms, To determine the stop criterion algorithm.

而我们现阶段的教育就太注重知识的灌输缺少兴趣的培养和引导。

我个人认为兴趣是求知的内在动力。

激发起学生的兴趣,学习就会积极主动,学得轻松而有成效。

但是学习兴趣不是天生的,主要在于教师如何引导学生,充分调动学生对学习的积极性和主动性,进而能创造性地学,最终达到优化课堂教学和提高教学效率的目的。

物理教学应该怎样去激发学生的兴趣呢? 下面就我在初中物理教学中激发学生学习兴趣的实践,谈谈自己的一些做法和体会。

一、创设各种情景,激发学生的学习兴趣。

兴趣是最好的老师,皮亚杰指出,活动受兴趣和需要的支配,教师在应该创设生动的情境,唤起学生的有意注意,调动学生思维的积极性、激发学习兴趣。

教师应根据学生的认知规律和学生已有的生活经验创设条件,引导学生主动学习、探究,成为学生学习过程中的组织者、引导者和协助者,引发学生思考,激发学生的学习兴趣。

比如,进入八年级《声现象》这一章时,就可以利用声音与日常生活中的联系创设问题情境。

例如(1)我们在说话和不说话的时候喉咙部位用什么不同?(2)在敲鼓时鼓面上放一些纸屑,纸屑会怎么样?(3)平时我们说话时,一张口马上就听见声音了,那么声音传播需要时间吗?(4)下雨时,为什么总是先看到闪电,后听到雷声呢?(6)《千手观音》这个舞蹈节目一定都知道,那么那些聋哑演员靠什么来感知音乐?在讲不同的内容时根据所授教学内容与教学目标、学生的认知水平和心理特征,精心选择适当内容,创设一些以学生为主体的、引人入胜的、轻松和谐的、具有探索性、启发性、创造性和科学文化氛围的、与学习主题的基本内容相关的,能够引起学生积极情绪反应的情境,这样可以很好地引起学生的共鸣,引发学生的兴趣,从而使学生享受后的知识的幸福感。

二、鼓励学生大胆质疑,勉励学生努力解决问题,引导学生成功使学生建立起成功内驱力,激发学生兴趣。

初中物理教学对学生质疑能力的培养有利于激发学生的创造性思维,有利于深入钻研物理知识,对物理产生兴趣。

现在的学生正是对一切事物充满好奇的年龄,大到宇宙小到原子对他们来说都是那么的神秘。

他们会产生各种各样的或浅或深奥甚至古怪的想法。

有些老师能够回答学生能过接受,有些老师能回答但学生不一定能接受,甚至有些老师都回答不了,这个时候老师不能搞“听话教育”,不能老师说什么就让学生接受什么,学生一下子接受不了的可以放一放,不要一下子否决学生的质疑,可以引导学生上网查科普资料去解决等,同
时鼓励他们尽量用自己已有的知识以及做一些小实验去理解和解释这个问题的产生的原因,让学生去体验科学探究的过程,最后享受成功带来的喜悦,是学生建立起成功内驱力,从而培养出科学探究的能力和对物理的信心与兴趣。

总之,好奇、质疑是学生的天性,是学习的原动力,教师面对学生强烈的好奇心和突发奇想的古怪问题时,一定要耐心解释,并鼓励学生积极解决问题,从而培养出对物理的兴趣。

三、学生动手操作实验观察实验现象与自然现象激发学生兴趣。

(一)、利用演示实验激发学生兴趣。

例如,教学《凸透镜》一课时,教师先左手拿出一个透镜,然后右手拿一张白纸,使透镜一面朝向窗外的风景,另一面朝向白纸,向左或向右移动透镜。

在白纸上就会出现窗外物体的像,看到这情况,学生不禁要问:透镜为什么有这种像呢?这样一下子激发起学生探究的兴趣。

(二)让学生积极主动参与实验,使其满足探究欲望。

苏霍姆林斯基说过:“如果教师不想方设法使学生进入情绪高昂和智力振奋的内心状态,就急于传授知识。

那么,这种知识只能使人产生冷漠的态度,而不动感情的脑力劳动就会带来疲倦”。

因此,教师要努力创造条件,让学生积极主动参与实验操作,指导学生细心观察,通过研究问题,分析、讨论等一系列学习活动,促使知识进一步内化,形成技能,满足了学生自行探究的愿望,从而激发学习兴趣。

(三)、开展课外实验观察活动,提高学生探究能力。

要培养学生的自然科学探究能力,课堂上的实验操作只是培养学生的兴趣,而却课堂教学有一定限制性。

因此,教师要以课内教学为基点,灵活多样地向课外延伸,扩宽实验观察途径,让学生感受异彩纷呈的大自然现象,达到培养对物理学习的兴趣。

四、营造良好的师生关系和学习环境培养学生物理的学习兴趣。

别林斯基说:“爱是教育的工具和媒介,对孩子的信任是成功的保障。

”所以教师对学生应该倾注爱心,融洽的师生关系是调动学生学习兴趣的前提。

如果一位学生因受到某位老师的斥责而产生畏惧感,那么他对该老师所教的学科是不会感兴趣的;反之,倘若一位学生因为受到有关老师的青睐和赞赏,那么他必定因为喜欢这位老师而喜欢该老师所执教的学科,所以教师应注意全面关心和爱护学生,多给他们表扬和帮助,在课堂教学中要充分发扬民主,让学
生敢于各抒己见,畅所欲言。

有了这样一个人民族平等、和谐融洽的学习环境,使学生感觉物理学习轻松愉快不再枯燥乏味,逐渐对物理学习产生浓厚的兴趣。

五、用现代教学手段,直观呈现物理教学过程,提高学生学习兴趣。

我们可以利用电脑,投影或动画等多媒体手段,是学生从看不见莫不这听不到的课本中走出来通过视觉,听觉多方面全方位的刺激,更使学生身临其境,感从身受,对学习的兴趣油然而生,对本节的教学过程产生深刻的印象。

使得一些大到宇宙小到基本粒子的运动、结构情况都能通过电脑模拟出来。

让学生能切切实实看得见,从而避免老师上面讲来空洞,学生学来枯燥。

兴趣是成才的基础,是成功的基石,是激情的源泉。

作为一个合格的物理教师我们必须把探究培养学生物理学习兴趣的方法和培养学生学习物理的兴趣作为首要任务之一,让学生在学习物理中感到轻松、愉快以及享受成功的喜悦,学习的快乐。
