中文摘要:
      乌兰乌珠尔-十字嵩银多金属矿是东昆仑成矿带西段地区近年来新发现的大型矿床。本文在总结该矿床成矿地质背景、矿床地质特征和成矿规律的基础上,探讨其矿床成因。结果表明,该矿区NW向和近EW向线性构造是控矿构造,矿体形态多呈似层状、脉状、透镜状,矿石类型以银铅锌矿石为主,矿石矿物主要有方铅矿、闪锌矿、含铁辉银矿、含铁铜辉银矿等,矿石矿物多呈稀疏浸染状、星点状、脉状分布;花岗斑岩的成岩过程提供了成矿物质来源,矿床形成于晚三叠世后碰撞伸展环境,属于与浅成-超浅成侵入岩有关的热液脉型银多金属矿。
英文摘要:
      Wulanwuzhuer-Shizisong ore deposit is a large Ag-polymetallic deposit newly discovered in the west part of the east KunlunShan ore belt in resent years.This paper deals with its metallogenic geological background, geological characteristics and metallogenic law and discusses the genesis. NW and nearly EW linear structure in the area is the ore-control structure. ore bodies are generally layeroid, veined, lenticular. Ag, Pb and Zn ore is the main ore type. Galena, sphalerite, Fe- argentite and Fe-Cu argentite are the main ore minerals occurring as sparse dissemination and veins. Ore material is derived from rock-forming process of granitic porphyry. The deposit is formed under Late Triassic post collision extension environment belonging to epigenetic-super epigenetic hydrothermal Ag polymetallic deposit.
