沂沭断裂带中段及西侧金矿成矿类型及成矿作用
Analysis of typical metallogenic types and mineralization of gold deposits in the Yishu fault belt,Shandong,China
摘要
Abstract
Metallogenic types and gold mineralization along the middle part of Yishu fault belt are studied so as to provide more theoretical basis and prospecting clues for gold exploration in this area. Two types of gold deposits occur in the study area,including post magmatic hydrothermal type and greenstone belt type. The former can be subdivided into the contact metasomatic type, cryptoexplosion breccia type and submarine volcano hydrothermal quartz vein type respectively.The Tongjing gold-copper deposit and Huamawan gold deposit are selected as a typical representative of the post magmatic hydrothermal type and greenstone belt type to study their geological features, orebody characters and mineralization.It shows that magmatism is the dominant factor to control the formation of post magmatic hydrothermal type deposits and the ore-controlling structures determine spatial distribution of ore.Regional metamorphism is the leading factor in gold mineralization to the greenstone belt type.The prospecting direction for future work is to find volcano hydrothermal gold deposit related to intrusive complex of Yanshan period,and volcano intrusive complex,explosion breccia and fault intersections are the key to exploration targets.关键词
