摘　　要：科克乃克含铜黄铁矿位于米什西沟-科克乃克沟一带,赋矿基岩主要为志留系阿哈布拉克组石英角斑岩。矿区含矿岩石中的金属矿物主要为黄铁矿、黄铜矿、褐铁矿,次为氧化铜,孔雀石。含矿岩石结构:细晶、变晶结构,构造:主要为致密块状构造、星散浸染状构造、星点状构造、浸染状构造和少数网脉状构造,氧化矿有似层状与土状构造,矿床类型为角斑岩型含铜黄铁矿型多金属矿床。找矿标志为受热液蚀变的石英角斑岩,以及在地表为氧化后的黄铁矿所形成的黄钾铁矾化。Kirk Nec Copper-pyrite deposit belongs to the area of Hamish Si Gou- Kirk Nec. The ore-bearing rock are confined to Silurian System Aghaburak formation of quartz keratophyre. Metallic minerals in the ore rock mining area are mainly pyrite,chalcopyrite,ferrohydrite, follow-ed by copper oxide, malachite. Ore-bearing rock composition： cryptomere,catablastic texture. Structure： mainly dense block structure,diffuse disseminated structure,the star point structure,pepper and salt structure and little net vein structure. Oxide bearing ore has stratoid and earthy structure. The type of deposit are defined to keratophyre pattern containing copper-pyrite, belongs to polymetal ore deposit. Quartz keratophyre suffered hydrothermal alteration as well as jarosite formed on the surface after the oxidation of pyrite is the proslaecting marks.
