河北省平山县秋卜洞银矿床成因类型分析

Genetic type analysis of Qiubudong silver deposit in Pingshan County,Hebei

平山县秋卜洞银矿床位于麻棚岩体外围多金属矿重点勘查区内,成矿条件优越。近年来的勘查工作找矿成果显著,仅银资源量已达中型以上接近大型矿床的规模,同时共(伴)生有Au、Pb、Zn等有益元素。在该矿区已有找矿成果基础上,对麻棚岩体外围(含本矿区在内)金银钼矿成矿规律及找矿方向进行研究,以黄铁矿(与成矿关系最密切)作为切入点,从成因矿物学的角度对矿床成因、找矿前景进行分析。结果表明:该矿床找矿潜力很大,具备发现大型银矿床的潜力,并可指导矿区的进一步勘查工作及区域找矿。

Qiubodong silver deposit in Pingshan County is located at the important exploration area of polymetallic deposits in the periphery of Mabang rock body,and the metallogenic condition is superior.In recent years,the prospecting results are remarkable,the silver resources have reached up to the large scale deposit,and there are some beneficial elements such as Au-Pb-Zn and so on.On the basis of the prospecting results,the metallogenic regularity and prospecting direction of gold,silver and molybdenum mineralization in the periphery of Mapeng rock body（including this mine area）are studied,with pyrite,which is closely related to the mineralization,as the starting point.From the perspective of genetic mineralogy,the deposit genesis and prospecting prospect are analyzed.The result shows that the deposit has a great prospecting potential to find the large-scale silver deposit.It can be referred to guide the further prospecting work in the mining area and regional exploration work.
