中文摘要:
      曼莱苏木铜金矿区是蒙古国南部曼莱-曼达赫成矿带上一个新发现的铜金矿区。该区地表广泛发育孔雀石化、褐铁矿化和黄铁矿化;孔雀石多交代石英产出,黄铁矿呈立方体嵌布于石英脉和凝灰岩中,局部黄铁矿呈薄膜状充填在裂隙中,褐铁矿化常成带状展布。通过对比分析,曼莱苏木铜金矿区与该成矿带上欧玉陶勒盖铜金矿床、查干苏布尔加铜(钼)矿床等两个大型矿床具有相同或相似的地层及其岩石组成,构造均主要由北东向和北西向断裂或线性构造构成,侵入岩的形成时代和岩石组成基本相似,由此可以看出,曼莱苏木铜金矿区成矿地质条件十分有利,并在野外调查分析的基础上圈定了乌兰敖包和奥尤特两个成矿远景区。
英文摘要:
      Manly Cu-Au mineralization zone is a new copper-gold zone discovered in Manly-Mandah metallogenic belt in southern Mongolia. Malachite, limonite and pyrite are widely found at the surface in this area. Malachite occur in quartz more. Cubic pyrites are disseminated in quartz veins and tuff. Pyrite is filled in fracture film-like. Limonite often has zonal distribution. Through comparative analysis, Manly copper-gold mineralization zone and two large deposits such as the Oyu Tolgoi copper-gold deposit and Tsagaan Suvarga copper (molybdenum) deposits have the same or similar formation and composition of rock. The tectonic is mainly composed of north-east and north-west faults or linear structures, and the era and the composition of intrusive rock are similar. It can be inferred that the ore-forming geological conditions of Manly Cu-Au mineralization zone is very beneficial, and two prospects, Ulan Obo and Aououte are delineated after field investigation and analysis.
