红石金矿地质特征及成因探讨

The geological characteristics and origin of Hongshi gold deposit

红石金矿产于义县组基性火山岩区侵入流纹斑岩岩墙中的一种次火山岩型金矿床。本文介绍了矿床成矿地质特征和成矿期次及矿物生成顺序;利用包体测温及同位素等测试资料探讨了矿床成因。

Hongshi gold deposit is a special type which occurs in intrusive rhyolite -porphyry dike in intermediate-basic volcanic terrain of the Yi Xian formation.In this paper, the minerogenetic geological character is studied and the mineralization epoches and mineral sequence are determined. The origin of the deposit explored by using the microprobe,inclusion thermometry. isotope assay etc.is also discussed.
