【摘要】Gaodi manganese-rich deposit is located in the Songgan National Manganese fully-equipped exploration region in Tongren,Guizhou Province, the resources of(332) +(333) manganese carbonate manganese-rich ore reached 71.668 million tons, the average grade is 25.75％, and the average thickness of the ore body is 4.52 m, the manganese-rich ore body occur in the high-scale super-large manganese deposit with a total resource of 161 million tons. It is composed of a single manganese-rich ore body. It is the first newly discovered large manganese-rich deposit in China. The amount is equivalent to twice the total amount of manganese-rich mineral resources in China. The genetic type belongs to the ancient natural gas seepage sedimentary manganese deposit,and the manganese-rich mineral developed in the central phase zone of the paleo-natural gas seepage sedimentary metallogenic system. The Gaodi manganese-rich deposit is located in the center of the unique\"crescent-shaped\"Lijiawan-Highland-Dowway(Grade IV) mantle basin in the early Nanhua period, and there are bubble-like fillings phosphorite-rich manganese deposit in the rhombohedral ore body. The north-north-east fault structure of the Yanshanian period is very developed,but it is mainly the upsteep and slow
down-plow-type normal fault. It does not touch the deep buried giant manganese ore body in the highland, so that the manganese-rich ore body is also very intact and easy to develop and utilize.%位于贵州铜仁松桃国家锰矿整装勘查区内的高地富锰矿床,(332)+(333)类碳酸锰富锰矿石资源量达7 166.84万吨,锰平均品位25.75％,矿体平均厚度4.52 m,富锰矿体赋存于总资源量达1.61亿吨的高地超大型锰矿床之中,由一个单一的富锰矿体构成,是我国新发现的首个特大型富锰矿床,富锰矿资源量相当于我国富锰矿资源量总和的2倍.成因类型属古天然气渗漏沉积型锰矿床,富锰矿产于古天然气渗漏沉积成矿系统中心相区.高地富锰矿床地处独特的\"新月形\"南华纪早期李家湾-高地-道坨(Ⅳ级)地堑盆地中心,菱锰矿体中均出现以块状构造夹被沥青充填的气泡状富菱锰矿石.地表燕山期北北东向的断裂构造十分发育,但主要为上陡下缓犁式正断层,未触及高地深部隐伏巨型锰矿体,以致富锰矿体保存亦十分完整,易于开发利用.
