河南嵩县银洞沟钼矿地质特征及矿床成因

Geological characteristics and genesis of Yindonggou molybdenum deposit,Songxian County,Henan Province

嵩县银洞沟钼矿区属马超营断裂多金属成矿带上发现的石英脉型钼矿床,通过地质勘查工作取得了较好的找矿矿果,认为熊耳群鸡蛋坪组地层对钼矿形成具有控制作用;顺层侵入的石英脉是区内重要的含矿体;区域内岩浆活动频繁,岩石种类繁多,岩浆活动为本区成矿提供了充足的热源和运移动力。通过对的矿体形态、矿石质量、成矿控制因素等的研究,分析了矿床成因,还指出了找矿标志,对以后的探矿工作具有一定的指导意义。

The Yindonggou molybdenum deposit in Songxian County is a quartz vein type molybdenum deposit found in the Machaoying fault polymetallic metallogenic belt,Through the geological exploration work,we have achieved good results in ore prospecting.It is considered that the formation of molybdenite is controlled by the formation of egg Ping formation of Xionger group;the quartz vein intruded along the layer is an important ore body in the area;the magmatic activity is frequent in the area,and there are many kinds of rocks,and the magmatic activity provides sufficient heat source and migration power for ore forming in the area.Based on the study of ore body shape,ore quality and ore-forming control factors,this paper analyzes the genesis of the deposit,and points out the prospecting criteria,which has certain guiding significance for the future exploration work.
