摘要
对金牙金矿床的主要地质特征作了较为详细的描述．对矿区氧化带进行了划分，并对金牙金矿矿石中金的分布及其赋存状态作了研究．结果表明，金的赋存形式主要有三种：即显微—超显微自然金包体形式、类质同像固溶体形式以及肢体吸附形式．在原生矿石中，载金矿物主要为毒砂，次为黄铁矿；在氧化矿石中，主要为粘土类矿物，碳质及褐铁矿等．
The main geological characteristics of Jinya gold deposits are described in detail. The oxidizedzones are divided,and the distribution and occurrence of gold in the gold ore of Jinya Deposits are studied. Theresults show that there are three kinds of occurring status: microscopic -u1tra - microscopic native go1d inclusions,isomorphous solid solution and absorbing colloid. Arsenopyrite is the ma jor gold carrier, in primary ore,pyrite is the minor. Clay minerals,carbonaceous material and limonite are the ma jor gold carriers in oxidizedore.
