胶东金银矿石英主微量元素化学成分特征及意义

The Main and Trace Element Chemical Composition Characteristics of Quartz in Jiaodong Gold and Silver Deposits

摘要:

石英是自然界分布很广的矿物，是金矿中重要的载金矿物之一，在金矿的各个成矿阶段均有出现。目前对胶东各类型金银矿中石英的化学成分标型研究还较薄弱。该文对胶东各类型金银矿中成矿期石英的化学成分进行了详细研究，结果表明，各金银矿中石英中K/Na，Al，NaKAl和(Na+K）Al参数均有显著区别，可用于区分胶东各类型金银矿，以上区别和各金银矿不同的成矿环境密切相关。以上结论对胶东各金银矿的成因和找矿具有借鉴意义。

Abstract:

Quartz is a widely distributed mineral in nature, and also is an important gold-bearing mineral in gold deposit. Now, the study on composition characteristics of quartz is in a low level. In this paper, the chemical composition of quartz has been studied in detail in Jiaodong various types of gold and silver deposits. The results show that the parameters of K/Na, Al, Na - K - Al and (K+Na) - Al in quartz of all the gold and silver deposits have the significant difference, which is used to distinguish various types of gold and silver deposits in Jiaodong. And the above differences are closely related to the metallogenic environment of each gold and silver deposit. Moreover, above result is helpful for the further study of gold deposits in Jiaodong.
