摘    要：讨论了鸡笼山金铜矿主要载金矿物的标型特征及与金矿化的关系,金矿物的种类、特征及其在矿石矿物中的赋存状态.确定了4种主要载金矿物和6种金的矿物.金的赋存状态包括显微可见金、次显微金和晶格金,分别以粒间嵌连、裂隙嵌连、包裹嵌连和类质同像形式赋存载金硫化物中.本文还用选择性溶矿方法定量地确定了黄铜矿、闪锌矿中上述3类金的含量分布.

Abstract: Jilongshan Au-Cu Deposit is a large-size gold deposit found recently in the Fe-Cu-Aumetallogenic belt of the middle-lower reaches of the Yangtse River. This paper discusses thetypomorphic characteristics of the main gold-carrying sulfides and their relationship with thegold metallization as well as the varieties, features and occurrence patterns of gold minerals.There are four main gold-carrying sulfides and six gold minerals. The gold occurs as micro-gold,submicrogold and latticegold.Additionally,the selective dissolution method is used todetermine the content distribution of the three types of gold in chalcopyrite and sphalerite.
