浅谈粤西地区金矿床成因类型及主要成矿作用

Genetic types and main mineralization of gold deposits in western Guangdong

粤西地区是广东省金矿床(点)的主要集中区,已知金矿床(点)主要分布在遂溪断裂以北、吴川-四会断裂以西、贵东断裂以南一带。按成因类型可划分为六个类型和两个亚类,其中,混合岩化热液型金矿床是粤西金矿最重要的金矿类型。成矿作用方面,其主要成矿作用类型有变质-混合岩化成矿作用、韧性剪切成矿作用和热液充填交代成矿作用。

Western Guangdong is the main concentration area of gold deposits (points) in Guangdong Province.Known gold deposits (points) are mainly distributed in the north of Suixi fault,the west of Wuchuan Sihui fault and the south of Guidong fault.According to the genetic type,it can be divided into six types and two subclasses.Among them,the migmatized hydrothermal gold deposit is the most important gold deposit in western Guangdong.In terms of mineralization,the main types of mineralization include metamorphic migmatization mineralization,ductile shear mineralization and hydrothermal filling metasomatism.
