6、韵律层理:
这种层理是在成分、结 构与颜色方面不同的薄层作 有规律地重复出现而显现的 层理构造。 这种韵律性重复的原因 是物质搬运或产生方式有规 律地发生交替变化造成的。 如:短期的,潮汐韵律;或 者是长期的,季节性韵律纹 层。
湖相泥岩中的季节性韵律纹层
7、均质层理或块状层理:
通常称为块状层理,呈现大致均质的外貌, 不具任何纹层构造的层理。特点是内部物质较均 匀,无论组分和结构都没有分异现象,故不显层 理。在细粒与粗粒沉积中都有块状层理出现。非 常快速地沉积而成或生物的强烈搅动作用形成。
块状层理、
平行层理、
递变层理、
韵律层理
二、原生沉积构造用于解释沉积环境
原生沉积构造序列是指一系列相互有联 系的原生沉积构造在垂向上的规律性组合,这 是由于沉积环境随时间的变化而使它们在垂向 上重叠起来的结果。因此,这种序列实质上反 映了形成它们的环境条件在垂向上的规律性变 化。根据瓦尔特相律,它们也代表了横向上或 区域上环境条件的变化。因为。只有横向上相 邻的相或相区才能在垂向上重叠起来,这就是 瓦尔特相律在环境解释中的应用。

沉 积 构 造
沉积岩的结构 是指构成沉积岩的矿物及岩
石碎屑的大小、形状以及空间组合方式。例 如碎屑岩的结构组分包括碎屑颗粒和填隙 物—杂基及胶结物。如何描述?
沉积岩的构造 是指沉积岩各个组成部分的
空间分布和排列方式。或者说,构造是指组
2) 透 镜 状 层 理 :
泥基质中夹有砂质透镜 体,其形成的条件与脉 状层理相反,它是在潮 汐水流或波浪作用较弱, 并且砂的供应不足,泥 质比砂质的沉积和保存 均有利的条件下形成的。

不同成因类型的第四纪沉积物,各具有一定的分布规律和工程地质特征,以下分别介绍其中主要的几种成因类型。

残积物、坡积物和洪积物残积物(Qel )(Qel为第四纪地层的成因类型符号)残积物是由岩石风化后,未经搬运而残留于原地的土,而另一部分则被风和降水所带走。

它处于岩石风化壳的上部,是风化壳中的剧风化带,向下则逐渐变为半风化的岩石。

它的分布主要受地形的控制,在宽广的分水岭上,由雨水产生地表径流速度小,风化产物易于保留的地方,残积物就比较厚。

在平缓的山坡上也常有残积物覆盖。

在不同的气候条件下、不同的原岩,将产生不同矿物成份、不同物理力学性质的残积土。

由于风化剥蚀产物是未经搬运的,颗粒不可能被磨圆或分选,没有层理构造。

残积物与基岩之间没有明显的界限,通常经过一个基岩风化层(带)而直接过渡到新鲜岩石。

残积物有时与强风化层很难区分。

一般说来,残积物是由于雨雪水流将细颗粒带走后残留的较粗颗粒的堆积物。

风化层则虽受风化作用的影响,但它是未被剥蚀搬运的基岩风化产物。

残积物中残留碎屑的矿物成分很大程度上与下卧基岩相一致,这是鉴定残积物的主要根据。

沉积岩的基本沉积构造总结(有图)

沉积构造Section two Sedimentary Structures沉积构造是由沉积物的成分、结构、颜色的不匀一性而表现出的宏观特征。

根据形成时间可划分为原生沉积构造和次生沉积构造(如周口店八角寨燧石结核)。

原生沉积构造是在沉积物沉积时或沉积后不久、以及其固结以前形成,因而是沉积环境的重要判别标志。

§2.1 物理构造(Physical Structures)层面构造[表面痕迹(surface marks), 底面印痕(bottom imprints)]和层理构造(bedding Structures)1、表面痕迹(Surface marks)——波痕(ripple marks), 雨痕(raindrop mark), 细流痕(rill marks), 泥裂(cracks)(1) 雨痕(Raindrop marks)圆形或椭圆形,在少雨区发育较好。

指示水上环境或半干旱环境,说明沉积物曾经出露水上(暴露标志)。

(2) 泥裂(Cracks)平面上为多边形,剖面上为“V”字形,由泥岩脱水、收缩或干化而成。

指示干旱气候或水上环境(暴露标志) 。

(3) 细流痕(Rill marks)由于细小水流侵蚀沉积物表面所形成的树支状痕迹。

指示水面下降或水上环境。

(4) 其它表面痕迹(The other surface marks)工具痕迹、障碍痕迹、弹跳痕迹等2 底面印痕(Bottom Imprints)底面印痕发育于沉积物(砂层)底部,为表面痕迹的铸型。

(1)槽铸型(Flute imprints): 平行水流方向的瘤状突起,上游端高而窄,下游端低而宽,可以指示水流方向。

(2)纵向脊和沟铸型(Longitudinal furrows and ridge imprints):相间排列的沟和脊,平行水流方向,但不能指示上、下游方向。

(3)沟铸型(Furrow imprint):窄而长的脊,平行水流方向。

• Planar stratification can easily be confused with planar cross stratification, depending on the orientation of a section (strike sections!)

Sedimentary structures
• Laminae and beds are the basic sedimentary units that produce stratification; the transition between the two is arbitrarily set at 10 mm • Normal grading is an upward decreasing grain size within a single lamina or bed (associated with a decrease in flow velocity), as opposed to reverse grading • Fining-upward successions and coarsening-upward successions are the products of vertically stacked individual beds

地层成因代号

地层成因代号

地层的沉积一般分为:ml--人工填土pd--植物层al--冲积层pl--洪积层dl--坡积层el--残积层eol--风积层l--湖积层h--沼泽沉积层m--海相沉积层mc--海相交互相沉积层gl--冰积层fgl--冰水积层b--火山堆积层col--崩积层del--滑坡堆积set--泥石流o--生物堆积ch--化学堆积物pr--成因不明沉积冲积物(al)河流在平缓地段所堆积下来的碎屑物,称为冲积物。

冲积物根据其形成条件,可分为:(1)山区河谷冲积物大部分由卵石、碎石等粗颗粒组成,分选性较差,大小不同的砾石互相交替,成为水平排列的透镜体或不规则的夹层,厚度一般不大。

一般地说,山区河谷的堆积物颗粒大,承载力高,但由于河流侧向侵蚀的结果也带来了大量的细小颗粒,特别是当河流两旁有许多冲沟支岔时,这些冲沟支岔带来的细小颗粒往往和冲积的粗大颗粒交错堆积在一起,承载力也因而降低。

(2)平原河谷冲积物河流上游的冲积物一般颗粒粗大,向下游逐渐变细。

冲积层一般呈条带状,具有水平层理,有时也成流水层或湍流层的交错层理。

在每一个小层中,岩性的成分就比较均匀,有极良好的分选性。

冲积物的颗粒形状一般为亚圆形或圆形,搬运的距离愈长,颗粒的浑圆度越好。

平原河谷冲积物可分为:河床冲积物、河漫滩冲积物、牛轭湖冲积物和阶地冲积物。

河床冲积物、河漫滩冲积物多为磨圆度较好的漂石、卵石、圆砾和各种砂类土,有时也有粉土、粘性土存在。

在同一地段上,河漫滩冲积物的粒度一般较河床冲积物为小。

在同一河漫滩上,靠河床近的冲积物的粒度比距河床远的为大。

牛轭湖冲积物只有当洪水期间成为溢洪区时才能形成,此时,细砂或粉质粘土就直接覆盖在原来已形成的泥炭或淤泥层上。

阶地冲积物的粒度常较河漫滩的为小,一般由粉质粘土、粉土和各种砂土所构成,有时也有卵石、圆砾的夹层。

在黄土地区,阶地则往往为各个不同地质时期的黄土所分布。

平原河谷冲积层中的地下水一般为潜水,由高阶地补给低阶地,再由河漫滩补给河水。

沉积岩的基本沉积构造总结(有图)

沉积岩的基本沉积构造总结(有图)

沉积构造Section two Sedimentary Structures沉积构造是由沉积物的成分、结构、颜色的不匀一性而表现出的宏观特征。

根据形成时间可划分为原生沉积构造和次生沉积构造(如周口店八角寨燧石结核)。

原生沉积构造是在沉积物沉积时或沉积后不久、以及其固结以前形成,因而是沉积环境的重要判别标志。

§2.1 物理构造(Physical Structures)层面构造[表面痕迹(surface marks), 底面印痕(bottom imprints)]和层理构造(bedding Structures)1、表面痕迹(Surface marks)——波痕(ripple marks), 雨痕(raindrop mark), 细流痕(rill marks), 泥裂(cracks)(1) 雨痕(Raindrop marks)圆形或椭圆形,在少雨区发育较好。

指示水上环境或半干旱环境,说明沉积物曾经出露水上(暴露标志)。

(2) 泥裂(Cracks)平面上为多边形,剖面上为“V”字形,由泥岩脱水、收缩或干化而成。

指示干旱气候或水上环境(暴露标志) 。

(3) 细流痕(Rill marks)由于细小水流侵蚀沉积物表面所形成的树支状痕迹。

指示水面下降或水上环境。

(4) 其它表面痕迹(The other surface marks)工具痕迹、障碍痕迹、弹跳痕迹等2 底面印痕(Bottom Imprints)底面印痕发育于沉积物(砂层)底部,为表面痕迹的铸型。

(1)槽铸型(Flute imprints): 平行水流方向的瘤状突起,上游端高而窄,下游端低而宽,可以指示水流方向。

(2)纵向脊和沟铸型(Longitudinal furrows and ridge imprints):相间排列的沟和脊,平行水流方向,但不能指示上、下游方向。

(3)沟铸型(Furrow imprint):窄而长的脊,平行水流方向。
