连州小带碳酸铁锰矿床地质特征及成因探讨

摘要

总结了连州小带碳酸铁锰矿床的矿体特征、矿石矿物特征、矿石结构、构造和矿石类型、围岩蚀变等地质特征。地层和构造是矿床的主要控矿因素，矿床的成因存在两个矿化期，主要形成于锰铁碳酸盐矿化期。确定小带碳酸锰铁矿床成因类型应为层控型铅锌铁锰矿床。%Ore body and mineral characteristics,ore structure,tectonic and type as well as wallrock alteration of iron carbonate manganese deposit in Xiaodai area is summarized. Formation and tectonic are the main ore-controlling factors. The ore deposit goes through two mineralization stages,primarily formed in ferromanganese carbonate mineralization period. It’s confirmed that the deposit falls into the category of strata-bound type lead-zinc iron manganese deposit.
