STUDY ON MINERAL CHEMISTRY OF DENGGEZHUANG GOLD ORE DEPOSIT IN JIAODONG

This paper has studied the mineral chemistry of Au-Agseries minerals, pyrite, quartz and 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 and Zn, and of poor Li.The REE data of pyrite and quartz shows that there are two mieralization fluid sources, that of the calcite shows the fluid is hypogenic and magmatic.
