摘要
分析了焦家金矿床中深部矿石中主要载金矿物———金属硫化物的物质组成及成分特征 ,查明了金银矿物的物质组成 ,对主要载金矿物黄铁矿、方铅矿、闪锌矿和黄铜矿的成分进行了重点分析 ,明确了各矿物的化学组成及分布状态 ,并与浅部矿石成分作了对比。同时 ,对矿石中微量元素特征进行了研究 ,分析了不同矿物中微量元素的相关性 ,指明了微量元素特征与成矿温度、压力等矿床成因方面的联系。
The mineral components and characteristics of main gold bearing mineral-metallic sulphide in the deep of Jiaojia gold deposit are analysed. The components of gold silver mineral are pointed out. The most important gold bearing mineral such as pyrite, galena, sphalerite and chalcopyrite are analysed emphatically, their chemical components and distributing features are identified, and compared them with the top level ore. At the same time the features of trace element and its relations in different minerals are studied. It is indicated that the trace element features are related to the ore formating temperature and pressure.
