| 中文摘要: |
| 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。 |

| 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. |
