摘要:
东秦岭包括陕南、予西南、鄂北广大地区,金矿资源十分丰富,点多面广。据初步统计,全区共有各类金矿床矿点及矿化点二百多处在全国占有重要地位。该区古老变质岩地层出露广泛,某些地层含金丰度偏高,构造复杂,秦岭纬向褶断带具有长期继承活动特征,各类岩浆岩分布广泛,变质作用及混合岩化作用十分强烈,对金矿成矿条件十分有利,金矿床具有显著的层控性质。 （一） 按照我国著名大地构造学家陈国达教授所创立的“地洼”学说,该区在大地构
Abstract:
The Eastern Qinling Mountains are located in the eastern part of the long-active and structurally complex Qinling latitudinal fold-fault belt.There, gold deposits（or mineralizations）occur in groups and zones,deposit types are many,orebodies are strictly controlled by strata and lithology, and source beds are numerous and widespread.The metallogenic epochs are mainly Caledonian and,subordinately, Yanshanian.The ore-forming processes are intimately related to structural and magmatic activity.Mineralization exhibits distinct inheritance and rejuvenation.Most of the deposits obviously show the stratabound character as well as some of the their own peculiar features.
