摘　　要：海相火山-热水沉积型锰矿床是蕴藏富锰矿石的最主要类型。西昆仑与西南天山结合部沉积型锰矿床富锰矿石的形成机制主要取决于以深源富锰含烃热液方式提供丰富的物源,Mn与Fe的分离与富集程度,特殊的构造盆地环境,构造-热动力场的形态规模、以及沉积海盆中有利的物理化学条件等。古海洋环境具有分层特点,沉积物中富含有机质,海洋微生物(细菌)参与锰的成矿并起到使锰质高度富集的重要作用。Marine volcano-hot water sedimentary manganese deposit is the most important type of manganese rich ore.Southwest of west Kunlun mountains and Tianshan junction type sedimentary manganese deposit are of rich manganese ore formation mechanism,which mainly depends on the deep hydrocarbon source rich manganese hydrothermal way.They provide a rich source of Mn and Fe separation and enrichment degree,including their special tectonic basin environment,construct,the shape of the scale,the thermodynamic field as well as favorable physical and chemical conditions in the sedimentary basins,etc.The ancient Marine environment is characterized by stratification,and the sediments are rich in organic matter.Marine microorganisms(bacteria)participate in the mineralization of manganese play an important role in the high concentration of manganese.
