湖北省竹溪县丰溪地区金矿成矿地质特征及找矿潜力分析

Geological characteristics and prospecting potential of gold deposits in Fengxi area, Zhuxi County, Hubei Province

阐述竹溪地区金矿床的地质特征,分析矿床成因,认为竹溪地区矿床是中低温热液成因的微细浸染型金矿床。指出Au矿化体主要赋存于泥盆纪薄层灰岩和浅变质的页岩、粉砂岩中。近东西向断裂与近南北向断裂交汇,并与东西向褶皱复合部位是成矿的有利地段,矿床具有金、银、砷、锑、钡分散流异常组合,对去找矿潜力进行分析。

The geological characteristics of the gold deposit in Zhuxi area are expounded,and the genesis of the deposit is analyzed.It is considered that the deposit in Zhuxi area is a micro disseminated gold deposit of medium low temperature hydrothermal origin.It is pointed out that Au mineralized bodies are mainly hosted in Devonian thin limestone,light metamorphic shale and siltstone.The ore deposit is characterized by gold,silver,arsenic,antimony and barium dispersive flow anomaly Association.The prospecting potential is analyzed.
