摘要
四川省茶树岭锰矿是近年来新发现的锰矿床,位于松潘—甘孜推覆造山带和扬子路块结合部位。通过对成矿地质背景及矿区地质特征进行系统研究,对矿床成因进行探讨,发现茶树岭锰矿呈层状、似层状产出于邱家河组上段含锰质碳硅质板岩中,为还原环境下Mn^(2+)与CO_(3)^(2-)直接结合而沉淀形成锰碳酸盐矿物,为典型的海相沉积锰矿床。对今后寻找同类型锰矿床起到一定的指导作用。
Chashuling Manganese Deposit in Sichuan Province is a newly discovered manganese deposit in recent years,which is located at the junction of Songpan Ganzi nappe orogenic belt and Yangtze road block.Based on the systematic study of the metallogenic geological background and geological characteristics of the mining area,the genesis of deposit is discussed.Chashuling manganese deposit occurs in layered and quasi layered manganese bearing carbonaceous siliceous slate in the upper section of qiujiahe formation.It is a typical marine sedimentary manganese deposit formed by the direct combination of Mn^(2+) and CO_(3)^(2-) in the reduction environment.It plays a guiding role in finding the same type of manganese deposit in the future.
