贵州铜仁松桃锰矿国家整装勘查区位于扬子地块东南缘的武陵山成矿带。著名的南华纪大塘坡早期(660-667 Ma)“大塘坡式”锰矿,形成于Rodinia超大陆裂解背景下的南华裂谷盆地。近年来,项目团队在该国家整装勘查区及黔渝湘毗邻区,通过长期的产学研协同攻关,厘清了锰矿大规模成矿作用的独特地质背景和构造古地理格架,发现了新的锰矿床类型——古天然气渗漏沉积型锰矿床,建立锰矿裂谷盆地古天然气渗漏成矿理论和深部隐伏矿找矿预测模型,圈定了若干找矿靶区。通过该整装勘查区的实践检验,累计投入各类勘查资金6亿多元,先后新发现了松桃西溪堡(普觉)、松桃道坨、松桃高地和松桃桃子坪四个隐伏超大型锰矿床。该整装勘查区新发现的超大型锰矿床数,占全球已发现超大型锰矿床总数约三分之一。新发现的锰矿资源量,超过了2011年全国锰矿保有资源量的总和,实现了我国有史以来锰矿找矿的最大突破,且锰矿找矿潜力依然巨大。使黔东成为中国锰矿资源最丰富的地区和新的世界级锰矿资源富集区。古天然气渗漏沉积型锰矿床成为中国最重要的锰矿床类型,是继传统的海相沉积型、沉积变质型锰矿床类型之后,全球最重要的三大锰矿床类型之一。
Guizhou Tongren pine country manganese ore prospecting area is located in the southeastern margin of the Yangtze block Wulingshan metallogenic belt. The famous Nanhua Ji Datangpo early (660-667 Ma) “Datang slope type ” manganese ore, formed in the South China rift basin under the Rodinia supercontinent cracking background. In recent years, the project team investigated the unique geological background and structural paleogeomorphology of large-scale mineralization of manganese ore through long-term collaborative work between universities and research institutes in the state-borne exploration area and the neighboring areas of Guizhou, Chongqing and Hunan Provinces and discovered new Manganese deposit type-paleo-natural gas leakage sedimentary manganese deposit, the paleo-gas leakage mineralization theory and the deep concealed ore prospecting prediction model of the manganese ore rift valley are established, and a number of ore-prospecting target areas are delineated. Through the practice test of the integrated exploration area, a total of more than 600 million yuan has been invested in various types of exploration funds. Four hidden volcanoes, namely Xixi Fort in Songtao County, Tuotuo in Songtao Road, Super large manganese deposit. The newly discovered super-large manganese deposits in the whole exploration area account for about one third of the total number of super-large manganese deposits in the world. The newly discovered amount of manganese resources surpassed the sum of the reserves of manganese ore in the country in 2011, realizing the biggest breakthrough in manganese ore prospecting in the history of our country and the prospecting potential of manganese ore is still huge. So Qiandong become China’s manganese ore resources in the most abundant areas and a new world-class manganese ore resource-rich area. The paleo-gas leakage sedimentary manganese deposit has become one of the most important types of manganese deposits in China and one of the three most important manganese deposit types in the world after the traditional marine sedimentary and sedimentary metamorphic manganese deposits.
