玉勒肯哈腊苏斑岩铜矿床位于新疆卡拉先格尔斑岩铜矿带.矿床主要赋存于花岗闪长斑岩、二长花岗斑岩及中泥盆统北塔山组辉斑玄武岩等火山岩中.矿区韧性剪切变形强烈,岩体和矿体糜棱岩化发育.矿区发育多种蚀变,由矿化岩体向外总体具钾长石化-黑云母化-硅化、绢云母化-青磐岩化蚀变分带特征.矿化主要分布于钾长石化-黑云母化-硅化蚀变带中.矿体呈脉状、透镜状、不规则状.矿化呈浸染状、团块状、团斑状、细脉浸染状和细脉状.成矿元素以铜为主,伴生金、钼、银.化探、磁法、激电测量及频谱激电测深等对矿区勘查工作具较好指示作用.矿区处于1∶5万物探激电异常和Au,Cu,Ag,Mo,Cr,Ni,Co等元素组成的化探异常中.从矿体不同勘探线剖面及水平标高的矿体形态及变化趋势分析,矿区南东深部有见矿可能,推断矿区北部频谱激电测深异常及1∶5万激电异常部位有矿体、矿化体存在. The Yulkeng Halasu porphyry copper deposit is located in the Karahangel porphyry copper belt in Xinjiang, with the deposits mainly occurring in the granodiorite porphyry, the monzonitic granite porphyry and the North Devonian group Plagioclase and volcanic rocks, etc. The ductile shear deformation of the mining area is strong, and the mylonitization of the rock mass and the ore body is developed. Various alterations occur in the mines, with the total feldspar-biotitization-silicification outward from the mineralized rock mass, Sericitization-epidote-petrochemical alteration zoning.The mineralization is mainly distributed in the K-feldsynaphylo-biotitization-silicification alteration zone.The ore bodies are veins, lenticular and irregular.The mineralization is dip dyeing Like, lumps, patchy, disseminated veinlets and veinlets. The metallogenic elements are mainly copper, associated gold, molybdenum, silver. Geochemical, magnetic methods, Mining exploration work with a good indication of the role of mining area in the 1: 500 000 geophysical and geochemical anomalies and Au, Cu, Ag, Mo, Cr, Ni, Co and other elements of the geochemical anomalies from the exploration of different ore exploration profiles and Horizontal elevation of the ore body morphology and trend analysis, the mine may see the depths of the south east, excavated the northern part of the mine spectral anomalies and 1: 500000 abnormal anomalies There ore mineralization exist.
