摘要
通过对田坝矿区铅锌矿床开展地质调查及研究,发现区内铅锌矿体产于中元古界昆阳群大营盘组第三段(Pt_(2)d^(3))浅变质灰黑色绢云板岩中;区内Ⅰ、Ⅱ、Ⅲ、Ⅳ、Ⅴ号主矿体,属于铅锌矿第Ⅱ类勘查类型;矿体并明显受北北东向张扭性断裂及北西向压扭性断裂控制;矿石自然类型为原生硫化矿石;工业类型为铅锌易选矿石;矿床成因类型为断裂构造控制的中低温热液充填型铅锌矿床。
Through geological investigation and research on the pb-Zn deposit in Tianba mining area,it is found that the PB-Zn deposit is located in the shallow metamorphic grayish-black sericornite SLATE of the third member of Daying Pan Formation(Pt_(2)d^(3))in the Middle Proterozoic Kunyang Group.The main orebodies No.Ⅰ,Ⅱ,Ⅲ,ⅣandⅤin the area belong to theⅡexploration type of lead-zinc mine.The ore body is obviously controlled by the NE-trending tensiontorsion fault and the NW-trending compression-torsion fault.The natural type of ore is primary sulfide ore.The industrial type is lead-zinc easy ore;The genetic type of the deposit is the middle-low temperature hydrothermal filling lead-zinc deposit controlled by fault structure.
