青海五龙沟金矿田两期蚀变作用及其找矿意义
Two Alteration Episodes of the Wulonggou Gold Ore Field in Qinghai Province and Its Prospecting Significance
摘要
Abstract
The Wulonggou gold ore field of Qinghai Province is an important gold ore-clustered area in the middle part of the eastern Kunlun orogenic belt.Gold deposits in the area are controlled mainly by three goldbearing structural fracture zones (Yanjingou zone,Yinshigou-Hongqigou zone and Sandaoliang-Kushuiquan zone).This study shows two episodes of alteration and mineralization occurred in the ore field:the early-stage alteration controlled by linear faulting structure and related to gold mineralization,and the late-stage polymetallic mineralization and alteration related to disseminated sulfide-rich granitic complex.The gold deposits formed at the early stage were partly destroyed by the alteration and polymetallic mineralization related to disseminated sulfide rich granitic complex at the late stage.The future prospecting for gold deposit should be carried out along the trend of faulting tectonic zone,where there are no many crosscutting fractures,especially no disseminated sulfide rich granitic complex.关键词
