格尔木拉陵灶火中游钼多金属矿地质成矿特征及成矿作用分析

摘要

拉陵灶火中游铜钼矿产于古元古代金水口岩群白沙河岩组斜长角闪岩段（Pt1b1）地层及中三叠世中粒石英闪长岩（T2δο）和白沙河岩组片麻岩接触带上，围岩有碳酸盐化、绿泥石化等蚀变，金属矿物为辉钼矿、黄铜矿，多成星点状、细脉侵染状；初步认为矿床成因为印支期构造-岩浆活动后形成的矽卡岩-斑岩型钼多金属矿床。%The Copper-Molybdenum polymetallic deposite of the LaLingZaoHuo occurs in Paleoproterozoic am-phibolite member of the Baisahe formation of JinshuiKou group strara and contact zones between the Triassic amedium-grain mphibole quartz diorite and Baishahe formation gneiss.The alteration distribution of the sur-rounding rock is carbonatization and chloritization. Metal ores are molybdenite and chalcopyrite present-ing as veinlet-disseminated and star-like and products.We preliminarily deem :after the tectonic-magmatic activity in indosinian ,the skarn type-porphyry type molybdenum polymetallic ore is formed.
