摘    要:大瑶山地区铜金多金属矿床主要由斑岩型、夕卡岩型、断裂-蚀变岩型3种类型的矿床(点)组成,矿种以金为主,伴有铜、银、铅、锌等矿化,构成了一个较完整的成矿系列组合,可划分2个矿床成矿系列和4个矿床成矿亚系列.成矿作用与浅成-超浅成岩浆岩关系密切.岩浆活动为矿床的形成提供了热源和热液.断裂构造提供了运移通道并控制着矿体分布.震旦系-寒武系是主要矿源层.建立了矿源层、构造、岩浆活动“三位一体”的区域成矿模式.

关 键 词:铜金多金属   矿床成矿系列   成矿模式   大瑶山   广西

Abstract:The copper and gold polymetallic deposits in Dayaoshan area are dominated by porphyry type,skarn type and fault-altered rock type,with mainly gold,associated by copper,silver,lead and zinc mineralization which form a completed metallogenic series.Base on the study on the characteristics of deposits and their tectonic setting,two metallogenic series including four sub-series are defined in the area.The metallogenesis is closely related to shallow-ultrashallow igneous rocks. The magmatic movement provides heat source and hydrothermal fluid for ore-forming.The faults perform as migration path and control the distribution of ore bodies.The Sinian-Cambrian strata are major source beds of ore.A regional metallogenic model of source bed-structure-magmatism is established.
Keywords:copper and gold polymetal  metallogenic series  metallogenic model  Dayaoshan  Guangxi
