内蒙古扎鲁特旗哈德营子铜-银多金属矿成矿地质条件及地球化学异常特征分析

分析了哈德营子铜-银多金属矿矿区地质背景、成矿地质条件及地球化学异常特征,认为该区火山活动十分强烈,而且具有脉动性、复合性,特别是在黄岗梁-乌兰浩特大断裂与脑德木-水泉大断裂交汇部位附近,放射状火山构造与EW向断裂系统的多次叠加复合,形成良好的导矿构造及容矿构造;该区1：20万金属量异常、1：10万原生晕异常、1：5万分散流异常与现有地质矿化信息吻合性好,其地质特征与该成矿带其它大中型铜-银多金属矿床极为相似,具有寻找次火山岩型大中型铜-银多金属矿床的潜力.

METALLOGENY AND GEOCHEMICAL CHARACTERISTICS OF THE HADEYINGZI COPPER AND SILVER POLYMETALLIC DEPOSIT IN ZHALUTE QI, INNER MONGOLIA

The paper analyzes geologic background,ore forming geological condition and geochemical anomaly characteristics.It is believed that there were fierce volcanic activities with pulsation and complexity,especially in the vicinity where huangganglian-wulanhaote fault meet naodemu-shuiquan fault and the radiate volcanic structures and EW strike fault were overlapped several times,which resulted in favorable passage and host tectonics for the ores.The anomaly of 1:10 000 scale primary halo and 1:5 000 scale dispersion flow etc are coincided with the information of the geology and mineral resources of the region..Metallogenic background of the area is much similar to middle scale porphyry copper deposit within the region.All of these evidences show that there is a potential for large or middle copper and zinc deposit of subvolcanic hydrothermal vein type within the area..
