| 摘 要： | 在西昆仑盖山北坡恰尔隆-库尔浪-塔木铜多金属-金成矿带内,对产于下石炭统基性火山岩中的块状硫化物铜矿床和产于上石炭统酸性火山岩中的块状硫化物铜矿床的成矿条件,通过代表性矿床进行了对比分析.认为两者形成的地质构造环境相同,形成时间相近,空间上毗邻,矿化特征又极其相似,具有密切的内在成因联系数.结合成矿地质环境,铜金矿化蚀变信息提取图像上显示的色晕异常带与已知铜、金矿床和矿点的叠合程度,以及水系沉积物地球化学异常条件,进行铜矿成矿预测,认为该成矿带内的阿属河-木孜塔格-带是铜矿找矿的有望地区. |

| Abstract: | Massive sulphide copper deposits in the Qiaerdong -Kuerlang -Tamu copper polymetallic -gold mineralizing belt are distributed in lower Carboniferous basic volcanic rocks and upper Carboniferous acidic volcanic rocks, By comparison of typical deposits, it is concluded that these two adjacent deposits in different strata have the same ore - forming background and genetic relations with similar ore - forming time and mineralizing characters. Combined with ore - forming background, superposition of colour halo anomaly belt in the mineralization - alteration information images with known Cu - Au deposits and spots, and geochemical anomaly of stream sediment survey, prospecting for copper is predicted. It is proposed that the Eweihe - Muzitage belt in the mineralizing belt has potential for copper prospecting. |
| Keywords: | western Kunkun back -arc rift ore character mineralizing prospecting volcanic type massive sulphide copper deposit |
