摘要: 新疆金山沟金矿床赋存在下石炭统巴塔玛依内山组火山岩中，受火山机构的环状、放射状断裂及叠加的NE向断裂裂隙控制.蚀变发育，分为线型和面型两类蚀变带，进一步划分出成矿期前、成矿期和成矿期后3期蚀变.流体包裹体及氢、氧、碳、硫、铅同位素特征表明，参与成矿的碳为岩浆源和地层的混合碳，硫、铅来源于地幔，金等成矿元素来自火山岩，成矿溶液为大气降水与岩浆水的混合溶液.矿床成因应属浅成中低温火山岩型金矿

Abstract: Located in the Laojunmiao area of Qitai County,Xinjiang,the Jinshangou gold deposit occurs in continental volcanic rocks of the Batamayineishan Formation.The ore zone and orebodies are controlled by circular and radial fractures of volcanic edifices and the late-superimposed NE-trending fracture-fissure system.So far totally 13 orebodies have been found.These orebodies are from 200 to 480 meters in length and 2.5 to 5.8 meters in width.The grades of various orebodies vary from 0.92×10-6 to 17.80×10-6.The mineralizing types include gold bearing welded tuff type,gold-bearing altered rock type and gold-bearing quartz vein type.
