宝山西部矿区砂页岩型铅-锌矿成矿地质特征及新区找矿预测

宝山西部矿区砂页岩型铅-锌矿是近年来探获的一种新类型铅-锌矿体,赋存在次级倒转背斜核部测水组砂页岩地层中,层间滑动带的虚脱空间是其容矿空间,断层规模决定其长度规模,矿体产状严格受构造控制。根据其成矿特征及成矿条件,利用类比法,预测新的找矿靶区。

Metallogenic characterisitcs of sandstone-shale type lead-zinc deposit in western mine of Baoshan and ore prediction in new area

The sandstone and shale type lead and zinc deposit in the mine ot western Baosnan Is a newly prospected new type of lead and zinc deposit, occurring in Cheshui Group sandstone and shale strata on the core of secondary reversed anticline, and the collapsed space of inter-layer sliding zone is the host fault, the scale of which controlled the length and occurrence of the orebody is strictly restricted by the structure. Based on the metallogenic characteristics and ore forming conditions, analogy method was used to predict new target area for the prospecting.
