摘要
本文通过对隐爆角砾岩型、斑岩-角砾岩钼(金)型、破碎带蚀变岩型及石英脉型等不同类型金矿床的分析对比,宏观上归纳了这几种类型矿床组合规律及异同点。强调断裂构造在这种类型矿床的形成中起着重要控制作用,构造-岩浆活动为该地区金的活化、富集提供了极为重要的条件。并推断不同类型金矿床是同一地质作用的结果。建立了熊耳山成矿区矿床系列模式。
Ore deposit association regularity and their simularities and differences are summed up after comparision and analysis of several types of deposits (cryptoexplosion breccia type, porphyry-breccia Mo(Au) type, fracture altered rock type and quarty vein type etc. )in Xiongershan district, Henan province. The important controlling role of fault structure for the formation of these types of deposits is emphasized. Structure-magmatic activity provides the critical condition for the activity and concentration of gold in the district. Various types of gold deposits are deduced as a result of the same geological process. The model of ore deposit series in Xiongershan metallogenic region is established.
