摘要
彩花沟含铜黄铁矿位于南天山萨阿尔明山早古生带非岩浆被动陆缘造山带东段.出露地层主要为具海相火山岩-火山碎屑建造特征的下泥盆统阿尔彼什麦布拉克组,具层控矿床形态特征.该矿床具成矿作用复杂、成矿多期性,成矿物质多来源的特点,其成因类型为火山喷发沉积-火山热液富集叠加-改造型含铜黄铁矿矿床.理论构建出的彩花沟含铜黄铁矿综合找矿模式,是以"中基性钙碱性火山岩+物探激电极化率异常和剩余重力异常+绢云岩化+硅化+孔雀石化+绿泥石化+石膏化"为核心的找矿模式.
Cai Huagou copper pyrite in South Tianshan Sa Aer tomorrow Paleozoic magmatism with non-passive margin of the eastern section of orogeriic belts, the main formation exposed to a marine volcanic rocks - pyroclastic the construction characteristics of the Aerbishi Maibulake group Devonian, with control of the deposit Morphological characteristics. Mineralization of the deposit with complex, multi-phase of mineralization, as sources of minerals and more features, its causes for the type of volcanic eruption deposition - volcanic hydrothermal enrichment stacking - of pyrite-copper deposit. From the theoretical point of view,Caihuagou copper pyrite comprehensive prospecting model： a ＂basic calc-alkaline volcanic rocks and IP geophysical polarization anomaly and residual gravity anomaly and sericite and Peacock and silicified and chlorite and gypsum. ＂
