摘要
铜金矿区位于塔里木板块东北缘,窑洞努如—公婆泉志留纪早古生代岩浆弧带上.华力西中晚期,岩浆热液沿构造薄弱区大量侵入,并携带了大量的Cu、Pb、Zn、Ag和Mo等元素,局部富集形成火山热液型铜矿化.通过勘查发现,矿区西矿段构造较复杂,矿石品位不稳定,各类系数变化较大,矿床类型与公婆泉铜矿相似,找矿远景较好;矿区东矿段矿体规模较小,矿体单一,矿区构造简单,矿石以热液(石英脉)型为主,矿石品位极不稳定.通过研究大峪口子铜金矿矿床地质特征及控矿因素分析,总结了找矿标志,为同类型矿床的勘查提供依据.
Abstract
Cu-Au mining area is located in the early Palaeozoic Silurian magmatic arc belt of Yaodong Nuru-Gongpoquan in the northeastern margin of Tarim plate.In the middle and late Hualixi region,the magmatic hydrothermal intrusion along the weak structural areas carried a large amount of Cu,Pb,Zn,Ag and Mo elements,and the local enrichment formed volcanic hydrothermal copper mineralization.Through the exploration,it is found that the structure of the western section of the mine is complicated,the ore grade is unstable,the various co-efficients change greatly,the deposit type is similar to that of Gongpoquan copper deposit,and the prospecting prospect is better.The ore body in the east section of the mining area is small in scale,with single ore body and simple structure.The ore is mainly of hydrothermal(quartz vein)type and the ore grade is extremely unstable.This paper analyzes the geological characteristics and ore-controlling factors of Dayukouzi copper and gold deposit,and it summarizes the prospecting criteria in providing a basis for the exploration of the same type of deposits.
