摘要
对义敦银锡多金属矿资源集中区成矿地质背景、主要成矿作用进行了分析,认为该区成矿与昌多阔-哈嘎拉构造岩浆岩带形成有着必然的内在联系,不同矿床组合显示了一个较完整岩浆热液成矿亚系列;该区找矿主攻矿床类型是矽卡岩型和构造破碎热液型两大类,主攻矿种为银、锡、铅、锌、铜。根据夏塞、措莫隆等典型矿床的矿化特征、控矿条件及找矿标志,通过对区内成矿地质条件分析,提出了找矿靶区优选建议,以期实现该区地质找矿的重大突破。
Skarn type and structural hydrothermal type are two major deposit type in the Yidun dense area of Ag-Sn-polymetallic mineral deposits with predomination of Ag, Sn, Pb, Zn, Cu deposits. This paper has a discussion on geological setting and major ore-formation which should be related to the Changduokuo-Hagala tectonomagmatic belt and puts forward some suggestions on prospecting targets based mineralization, ore control conditions and ore criteria of typical deposits such as Xiasai and Cuomolong deposits.
