摘要: 当糜棱岩中金元素的含量足以满足工业利用，即在糜棱岩中可圈出独立的金矿体时，这种金矿床便可称为糜棱岩型金矿床.糜棱岩型金矿床是"中国金矿床工业类型"中的重要类型之一.此类金矿床多分布在古老地块周边长期活动的构造带之中.介绍了糜棱岩型金矿床的赋矿岩系、控矿构造、矿床、矿体、矿石以及含金矿物等地质特征.同时，对金成矿地质环境及矿床成因等作了探讨

Abstract: Mylonite-type of gold deposits means the ones that occur in mylonite independantly The ore bodies are gold-bearing mylonite series The mobilization,migration,enrichment and deposition of Au element during the metallizing process are closely correlated to the formation and evolution stages of mylonite Gold ore bodies are strictly controlled by mylonite belts As the wall rock and ore body are both mylonite,there is no obviously boundary between them The occurrences of ore bodies are stratiform,lentiform and vein,of which the stratified ore bodies are economically significant,although the amount is relatively less Most of ore bodies occur in lens or veins,characterized by swither,composite,swell and parallel.
