摘　　要：贵池矿集区银坑洞银多金属矿床位于下扬子地层分区,是一受构造控制的中低温热液蚀变矿床,银多金属资源量具有一定规模。本文对矿区地质特征、矿床地质特征和成矿条件进行了分析,总结了找矿标志。研究表明:银坑洞矿床的矿体主要产于上泥盆统五通组、石炭系地层中,是与其层间逆冲、逆掩断层作用密切相关的中低温热液型银金多金属矿床;本区成矿条件有利,极具寻找中低温热液型银多金属矿找矿潜力。研究结果可为银坑洞及其附近相同类型矿产勘查工作提供参考。Yinkengdong silver-polymetallic deposit in Guichi ore concentration area is located in the sub-zone of lower Yangtze strata.It is a medium-low temperature hydrothermal alteration deposit controlled by structure,with sizable silver-polymetallic resources.In this paper,the geological features of the mining area,ore deposit and metallogenic conditions were analyzed,and the prospecting criteria were summarized.The study showed that the ore bodies of Yinkengdong deposit mainly occurred in the upper Devonian Wutong Formation and the Carboniferous strata,and it was a medium-low temperature hydrothermal silver-gold polymetallic deposit closely related to the interlayer thrust and overthrust faulting.The ore-forming conditions in this area were favorable,and the medium-low temperature hydrothermal silver polymetallic deposits had great prospecting potential.The research results can provide reference for the exploration of the same type of mineral resources in Yinkengdong and its vicinity.
