摘要
白银厂铜多金属矿是产于北祁连海相火山岩带中的典型矿床。本文通过对白银厂小铁山多金属矿床成矿地质背景、赋矿地层、导矿容矿构造、岩浆活动以及矿体特征、矿石特征、围岩蚀变等的总结归纳,结合前人在成矿时代、成矿机制方面的研究成果,总结了区域成矿背景和矿床的相关找矿标志,以期为该海相火山岩带同类型矿床的找矿工作有所启发。
s： The Baiyinchang copper polymetallic deposit is a typical deposit in marine volcano rock belt in the north of Qilian. This paper summarized the metallogenic geological background , ore bearing strata, ore guiding and hosting structure, magnmtic activity and orebody characteristics, ore characteristics, wall rock alteration, and so on. By referencing previous research results in the metallogenic epoch and metallogenic mechanism, summarized prospecting marks of the regional metallogenic background and ore deposit. It could be an inspiration for the prospecting work of the same type deposit in the marine volcanic rock belt.
