摘　　要：新疆准噶尔东北缘蕴都卡拉矿床是世界上少见的金铜钴组合,位于新疆阿尔曼太金、铜、铁、铬成矿带,主要赋存于泥盆纪中基性火山岩及后期侵位的石炭系闪长岩中。矿区韧脆性剪切变形强烈,矿化蚀变发育,主要为黄铜矿化、黄铁矿化、碳酸盐化、硅化、蛇纹石化、绿泥石化。矿体主要分布于中泥盆统北塔山组玄武岩和闪长岩中的黄铜矿化-黄铁矿化-硅化带中。矿体呈脉状、似层状和不规则状。矿床处于航磁异常和Au、Cu、Ag、Mo、Cr、Ni、Co等元素组成的化探异常中,异常带呈北西-南东向延伸,对矿床勘查具有较好的指示作用。本文研究了矿床的地质特征,总结了找矿方法,构建了综合找矿模型,提出了进一步找矿方向,以期为矿区进一步勘查提供依据。The Yundukala Au-Cu-Co deposit in the northeastern margin of Junggar is located in the Aermantai Au-Cu-Fe-Co metallogenic belt in Xinjiang,mainly occurring in intermediate-basic volcanic rocks and later emplaced diorites.The ductile-brittle shear deformation in the mining area is strong,mineralization and alteration are developed,mainly including chalcopyritization, pyritization, carbonatitation, silicification, serpentine petrification and chloritization. The ore bodies are mainly distributed in the chalcopyritization-pyritization-silicification zone in the basalt of, and the diorite intruding in, the Middle Devonian Beitashan Formation. The ore bodies are vein-like, layer-like and irregular.The deposit is in the aeromagnetic anomalies and the geochemical anomalies composed of elements such as Au,Cu,Ag,Mo,Cr,Ni,Co. The anomalous zone extends in the northwest-southeast direction and is a good indicator for the exploration of the deposit. In this paper, the geological characteristics of the deposit is studied,the prospecting method is summarized,the comprehensive prospecting model is constructed and further prospecting direction is proposed to provide a basis for further exploration work in the mining area.
