摘要
青海省都兰县金矿主要分布于蚀变花岗岩、碳化片麻岩及构造角砾岩中,矿石强蚀变。通过地球化学、物理及矿石特征,确定矿化带内发育褐铁矿化、臭葱石、黄钾铁矾等是重要找矿标志。
The gold deposit in Dulan County,Qinghai Province is mainly distributed in altered granite,carbonized gneisses and structural breccia,and the ore is strongly altered.According to the geochemical,physical and ore characteristics,it is determined that the development of limonite,osmolyte and jarosite in the mineralization zone are important prospecting indicators.
