摘要
铜官山铜矿床是我国著名的铜产地,首次在罗村矿段圈定出具有工业意义的金矿体,是铜官山矿区找矿工作的一个突破。通过野外勘查分析得出金矿体主要赋存在矽卡岩、大理岩及闪长岩交汇处的次级小断裂或裂隙中,受岩浆岩、地层的岩性、接触带构造及次级小断裂或裂隙等多种因素控制,而金大量析出则发生在热液后期的碳酸盐阶段。
The Tongguanshan copper deposit is a famous copper occurence in China. It is a big breackthrough in prospecting in the area to outline economic gold orebody in Luchun district for the first time. It is concluded from field observation and analysis that the gold orebody mainly occurs in the secondary fractures or fissures at the intersection part of skarn marble and dierite,controlled by several factors such as magmatite lithology of the strata, structure of contact zone and secondary small fraetures and fissures, with a gold deposition in large quantity at carboniferous stage in later hydrothermol period.
