新疆哈密市白干湖西铅锌矿矿床特征及找矿模型建立

Deposit characteristics and prospecting model establishment of the Bai Gang Hu Pb Zn deposit, Hami, Xinjiang

新疆哈密白干湖西铅锌矿位于阿奇山-雅满苏-沙泉子铁锰铅锌金铜矿带,含矿地层为下石炭统雅满苏组海相碎屑岩、碳酸盐岩。雅满苏组(下石炭统)正常碎屑岩夹碳酸盐与以及碱长花岗岩(三叠纪)相互交接的部位是该矿的主要产出区域。灰岩呈中薄状的灰白色以及砂岩(凝灰质)和细粒岩屑砂岩(灰、灰绿色)是区内的主要矽卡岩原岩,该矿成因类型为矽卡岩型特征。文中笔者对白干湖西铅锌矿矿床特征进行总结,并建立较为详细的找矿模型,为该区进一步找矿提供参考。

The Western lead-zinc deposit in the Bai Jigan Lake in Hami, Xinjiang, is located in the azigan - jacousu - shaquan iron, manganese, manganese lead, zinc and gold copper ore belt, and the ore bearing stratum is the lower Carboniferous ijan - Siu formation marine clastic rock and carbonate rock. The main part of the mine is the Jican Su group （Lower Carboniferous）, where the normal clastic rocks contain carbonate and alkali feldspar granite （Triassic）. The gray and white limestone and sandstone （tuff） and fine grayish sandstone （gray and gray green） are the main skarn rocks in the area, and the genesis of the ore is a skarn type. In this paper, the author summarizes the characteristics of the deposit in the Bai Gang Xi Pb Zn deposit, and sets up a detailed prospecting model, so as to provide references for further prospecting in this area.
