摘　　要：玉依塔斯铜金矿是近年来新疆准噶尔东北缘找矿勘查工作的新突破。在研究矿区地质、地球物理、地球化学异常特征基础上,查明控矿因素。认为中泥盆统北塔山组为赋矿地层,泥盆系石英闪长岩和花岗闪长岩为含矿岩石,矿区NW向、NE向构造为控矿构造。矿区具弱正磁异常特征及低阻中高极化激电特征,及Au,Cu,Mo,Ag,Sb,Ag,As等元素岩石地球化学综合异常特征,对矿床勘查具较好的指示作用。在此基础上,构建矿床地质、地球物理、地球化学综合找矿模式。The Yuyitasi copper-gold deposit is a new breakthrough in prospecting work in the northeastern margin of Junggar,Xinjiang in recent years.Based on research of characteristics of geology,geophysical and geochemical anomalies,the ore-controlling geological factors of this ore district has been found out,it’s considered that the middle of Devonian Beitashan group is the advantaged ore-bearing layer,Devonian quartz diorite and granodiorite are primary ore-bearing rocks,structures in the direction of northwest and northeast is the most important ore-controllingstructures.The indicators and information for prospecting of this ore district has been confirmed,it’s considered that characteristics of weak positive magnetic anomalies,low resistivity and high polarizability,combined geochemical anomalies of Au,Cu,Mo,Ag,Sb,Ag and As,can be used as effective prospecting indicators.On this basis,the integrated information prospecting model of this deposit has been put forward,which may be helpful for prospecting in deeper sections and periphery of this ore district.
