摘要 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。 Songtao manganese fully equipped exploration district situated in Wuling mountain metallogenic belt of southeast Yangtze block. The famous ‘Datangpo type'manganese deposit in early Datangpo,Nanhua period formed in Nanhua rift valley with background of Rodinia supercontinent breakup. In recent years,in the district and nearby area,by long time's hard work,the team has found out the special geologic background and tectonic paleogeography frame,discovered new manganese type-Ancient natural gas seepage sedimentary-type manganese deposit,built ancient natural gas seepage metallogenic theory and deep concealed manganese exploration model of manganese rift valley,determined several target areas. By practice,it has invested 600 million and founded Xixibao(Pujue),Daotuo,Gaodi and Taoziping super large concealed manganese deposit. The number of new founded manganese depoisit is one third of the founded manganese deposit in the world,the reserve exceeded the maintain resource of the country in 2011,it's the biggest breakthrough of manganese exploration in the country and the exploration potential is big in the future. East Guizhou became most rich area of manganese in China and new world-level manganese concentration area. Ancient natural gas seepage sedimentary-type manganese deposit has been the most important manganese deposit in China,it's also one of the most important manganese deposit after traditional seafacies sedimentary manganese deposit and sedimentary metamorphic manganese deposit.
