| 中文摘要: |
| 位于贵州省松桃县乌罗镇高地村的高地锰矿床，是贵州省地质矿产勘查开发局103地质大队应用南华纪锰矿裂谷盆地古天然气渗漏成矿理论和方法，在贵州铜仁松桃国家锰矿整装勘查区找矿实践检验中，继近年新发现普觉、道坨、桃子坪等三个隐伏超大型锰矿床之后，又新发现的隐伏超大型锰矿床。该矿床属于典型的古天然气渗漏沉积型锰矿床，地处李家湾-高地-道坨南华纪地堑盆地中心区域，位于古天然气渗漏喷溢成矿系统的中心相区，以致该矿床的矿体平均厚度、锰矿平均品位是目前该地区该类型所有锰矿床之最。地表发育成矿后期(燕山期)以冷水溪断层(F3)为代表的犁式正断层，目前控制的隐伏菱锰矿体均分布在其下盘，由于地表相关系列断层均未穿过F3断层，故深部隐伏锰矿体保存完好，尚未圈边，深部仍有较大找矿潜力。 |

| The Gaodi manganese deposit in Gaodi Village, Wuluo Town, Songtao County, Guizhou Province, is a newly discovered concealed super-large manganese deposit was discovered with the theory and method for the exploration of ancient gas leakage in the Nanhuaji manganese ore rift basin in the 103 Geological Party of the Guizhou Provincial Bureau of Geology and Mineral Exploration and Development, in Tongren, Guizhou. In the prospecting practice test of the Peach National Manganese Mine Ready Exploration Area, following the recent discovery of three concealed super-large manganese deposits such as Pujue, Daoyu and Taoziping, . The deposit belongs to a typical paleo-natural gas leakage sedimentary manganese deposit. It is located in the central area of the Lijiawan-Highland-Daoyu Nanhuaji mantle basin. It is located in the central phase of the paleo-natural gas seepage and spillover ore-forming system, so that the average thickness of the ore body and the average grade of manganese ore are currently the highest of all manganese deposits of this type in the region. In the late stage of surface development and mineralization (Yanshan period), the plough-type normal fault represented by Lengshuixi (F3) is distributed in the lower plate of the current concealed rhombohedral ore body. Since the series related faults have not passed through the F3 fault, The deep concealed manganese ore body is well preserved and has not been circled, and there is still a large potential for prospecting in the deep. |
