摘　　要：本文从河南嵩县祁雨沟区域地质特征、矿化角砾岩体的矿床地质特征入手,分析研究本区含金角砾岩体矿体的展布形态特征、矿物生成顺序和围岩蚀变特征,以及对金矿化富集规律和矿床成因类型的研究分析,认为祁雨沟金矿床是产于燕山期热液角砾岩筒内,是秦岭成矿带熊耳山矿田中一个典型的与次火山岩有关的隐爆角砾岩型金矿床。目前在该区已发现30余个类似的含矿地质体,通过对该点的剖析,对扩大区域找矿远景具有一定的现实意义。Regional geology of the Qiyugou gold deposit was investigated, including its geological characteristics of mineralized breccia. These investigations primarily focused on the morphological features and sequence, wall rock alteration and they indicated that the Qiyugou gold deposit occurred in a Yanshanian hydrothermal breccia pipe and it is a typical gold deposit characterized by cryptoexplosion breccia which is related to subvolcanic rocks in the Xiongershan ore field in the Qinling metallogenic belt. More than 30 similar ore bodies have been found in the study area, and these investigations are significant to enlarge the prospective exploration area.
