摘要
在阐述上朝铅锌矿床地质特征基础上,对矿床的控矿因素进行分析,总结了找矿标志。矿体在泥盆、石炭纪的地层中均有产出,且矿化有选择性地在碳酸盐岩与细碎屑岩和白云岩的接触带发育,矿化岩石岩性主要为凝灰岩、白云岩、构造角砾岩等。矿化明显受层间破碎带及断裂控制,结合区域矿床对比,认为上朝铅锌矿床成因属层控—热液蚀变叠加型铅锌矿床。
Based on the descriptions of geological properties of Shangchao lead-zinc deposit, the authors comprehensively expounded the ore-controlling factors, summarized the prospecting criteria. The ore bodies were occurred in Devonian and Carboniferous strata and selective mineralization was developed in the contact zone of carbonate rocks, elastic rocks and dolomite. The lithology of mineralized rock was mainly tuff, dolomite and tectonic breccia. Mineralization phase was significantly affected and controlled by inter-layer fracture zones and fractures, in combination with the contrast of regional deposits, the authors concluded that the origin of lead-zinc deposit in Shangchao was a stratabound-hydrothermal altered superimposition type.
