胶东邓格庄金矿床矿物化学研究

本文研究了胶东邓格庄金矿床金银系列矿物、黄铁矿、石英和方解石的化学成分,金银系列矿物主要为银金矿和金银矿,含Pt等微量元素,与金矿化关系密切的黄铁矿以Fe亏损占优势,富Au、Te、As和Ag为特点;石英具高的Al、K、Cu、Pb和Zn,低的Li含量;黄铁矿、石英和方解石的稀土元素组成指示成矿热液可能有二种来源,方解石的稀土元素组成指示成矿热液为岩浆或深部来源。

STUDY ON MINERAL CHEMISTRY OF DENGGEZHUANG GOLD ORE DEPOSIT IN JIAODONG

This paper has studied the mineral chemistry of Au－Agseries minerals, pyrite，quartzand calcite. The most Au－Ag series minerals are electrum and kustelite，which include Pt，etc.，as trace elements；the pyrite intimately related to gold mineralization is mainly of Fe－absence，rich Au，Te，As and Ag，the quartz is characteristic of rich Al，K， Cu， Pb andZn, and of poor Li．The REE data of pyrite and quartz shows that there are two mieralizationfluid sources，that of the calcite shows the fluid is hypogenic and magmatic.
