摘　　要：以矿床成矿系列理论为基础,提出黔东及毗邻区新元古代锰矿、重晶石矿大规模成矿作用主要是流体成矿作用,又有沉积成矿作用。在南华裂谷盆地的不同演化阶段,形成新元古代至早古生代黑色岩系有关的锰、重晶石、磷、镍、钼、钒、铀、页岩气等矿床成矿亚系列。提出区域性的导矿构造是新发现北西向中元古代基底中的铜仁古裂谷。对铜仁古裂谷与近东西向南华裂谷盆地同生断裂、次级地堑盆地等配矿构造的交汇处,形成含矿流体底辟通道,控制形成了系列超大型锰矿床、超大型重晶石矿床等区域成矿规律进行了论述。在总结贵州新元古代锰矿、重晶石矿区域成矿规律的基础上,建立了区域成矿模式,对成功指导实现锰矿和重晶石找矿突破进行了介绍。In this metallogenic study,we propose that ore-forming fluids play a vital role in massive manganese and barite mineralization in eastern Guizhou and its adjacent areas,although sedimentary processes may be also involved.In the research area,we documented black shale-related deposits formed between Neoproterozoic and Early Paleozoic.The deposits include,but not limited to,manganese,barite,phosphorous,nickel,molybdenum,vanadium,uranium,and shale gas.Moreover,we propose that Tongren Paleo-rift basins of the newly discovered northwestern-trending basement could be the regional ore-forming structures for these deposits.Field evidence suggest that the massive manganese and barite ore deposits locate at the intersections of east-west-trending rift basins,syngenesis faults and secondary graben basins.Based on the above-mentioned proposals and discoveries,we established regional metallogenic models that have led to the breakthrough of manganese and barite ore explorations.
