【摘要】 阿吾拉勒山东段是新疆重要富铁矿成矿带,形成于伊犁石炭纪裂谷环境。产于海相火山—沉积岩系中的赤铁矿和块状含铜黄铁矿,发育红碧玉、重晶石喷流岩,S、Pb、H、O同位素反映成矿物质来源于深部地壳或上地幔,成矿流体源自岩浆水,并有海水混入,属于火山喷流沉积矿床。产于基—中性火山岩系中的磁铁矿,形成于火山机构附近,属矿浆喷溢型矿床。两个层位的铁(铜)矿是在同一成矿环境下形成的矿床组合,预示该地区铜矿具有较大找矿前景。更多还原

【Abstract】 The eastern part of Awulale area is an important iron-rich ore forming belt in Xinjiang Province.Ores was formed in Carboniferous period.Hematite and massive copper-bearing pyrite occurred in marine facies sedimentary rock series.Red jade and barite spouting rocks are developed.S,Pb,H, and O isotopes indicated that ore sources were original from the deeper crust or the upper mantle,and ore-forming fluids were magmatic water mixed with sea water.The deposit belongs to volcanic exhalation sedimentation type.Magnetite occurred in intermediate-basic volcanic rocks was formed nearby volcanic apparatus,and belong to magmatic eruption type.Two layers of iron(copper) ores formed in the same mineralizing environment suggested that there are a great prospecting potential for copper ores in the area.更多还原
