    新疆东昆仑鸭子泉—维宝一带地质成矿规律浅析

    Preliminary Analysis for Geological Characteristics and Metallogenic Regularity of Yaziquan-Weibao Belt in East Kunlun Mountains,Xinjiang

    • 摘要: 东昆仑祁漫塔格地区位于东昆仑Fe-Pb-Zn-Cu-Co-Au-W-Sn-多金属-盐类成矿带中,随着地质勘查进程的不断深入,该区现已成为铁矿、钨锡矿、铜矿、铅锌矿等矿产的矿集区,其地质找矿潜力非常巨大。笔者从成矿地质条件、区域地球物理场、区域地球化学场等角度对鸭子泉—维宝地区的成矿规律进行了剖析,并结合白干湖钨锡矿、维宝铅锌矿等典型矿床的特征对区内的各主要成矿元素的成矿类型、成矿期次进行了较为系统的归纳,认为该区具有寻找岩浆热液型钨锡矿、层控型铅锌矿、矽卡岩型铁铜多金属矿等矿产的有利地质条件,并对以上各类型矿床的产出环境、成矿时代、沉积(变质)建造、岩浆建造、控矿构造等成矿地质条件进行了总结,建立了区域成矿模式。

       

      Abstract: The Qimantage area lied in east Kunlun Fe-Pb-Zn-Cu-Co-Au-W-Sn polymetallic and saltdeposits belt.As limited by higher altitude,lower temperature,lack of oxygen and other poor natural conditions,there ore exploration has little been done in the past.But in Qinghai province,some new ore deposits have been found since 2000.Recently,as the more supports obtainded from government,the more geology research works and ore deposit exploring works have been done.Followed by a series of large or giantore deposits has been explored,such as Baiganhu W-Sn ore deposit,Dimunalike Fe ore deposit and Weibao Pb-Zn ore deposit,now in this area there has been a large cluster of ferrous and in-ferrous (such as Fe,Cu,Pb,Zn,W,Sn) mineral deposits,and a hot spot of ore deposit exploring has come into existence.And it would be an important metal resource reservoir,if more exploring and research works have been done and more funds have been obtained.Here,based on geological,geophysical and geo chemical characteristics of thebelt,the metallogenic regularity of Yaziquan-Weibao beltis preliminarily studied,characteristics of geneses of ore deposits are compared and disting uished,and a regional metallogenetic model is pointedout.
