| 摘 要： | 新疆阿克陶县恰尔隆一带1：5万区调工作中曾在库科西力克一带发现数个具有一定工业价值的矿点，这些矿点位于西昆仑铜钼多金属元素富集带，其矿种齐全，涉及Au、Ag、Cu、Pb—Zn、M0、W和Fe等，分布较为集中，资源前景较好，找矿潜力巨大。本文从矿床地质及元素地球化学的角度对一些典型矿点进行了系统调查、采样、分析及研究，发现库尔尕斯金铜矿点主成矿元素中Ag、Cu和Pb具有一致的成矿阶段，而Au受后期构造作用可能滞后富集成矿。同时各矿点间REE含量及分布模式存在较大的差异。除库尔尕斯金铜矿点外，各矿点中矿石和围岩REE总量和分布模式差别也较为明显。认为库科西力克一带各矿点在成矿地质条件上具有一定的联系，成矿物质可能主要来源于深部，主要受区域性断裂（库科西力克断裂）及岩浆活动的影响，但各矿点之间具有各自的成矿特点，这与各矿点不同的矿床类型相关。 |

| Abstract: | Several mineralization spots with high potential of industrial values were found in the Kukexilike region during the 1 ： 50000 regional geological and mineral resource survey of the Qiaerlong region, Aketao County, Xinjiang. These deposits are located within the enrichment zone of Cu-Mo polymetallic elements. These mineral- ization spots cover a variety of ore types, e.g., Au, Ag, Cu, Pb, Zu, Mo, W and Fe, with high density, implying promising potential for future geology and geochemistry. In have consistent mineralization exploration. Here we systemically studied typical mineralization spots in terms of Kuergasi Au-Cu ore spot, we find that main ore-forming elements, Ag, Cu and Pb stages, but main mineralization of Au was controlled by late tectonic evolution. The REE concentrations concentration of ore Kuergasi Au-Cu ore and distribution patterns of different spots are significantly different. The REE patterns and bodies are also dramatically different from the corresponding wall rocks, with the exception of spot. We propose that these mineralization spots may have some genetic relation. The mineralization materials came mainly from depths strongly affected by regional fault （Kukexilike fault） and magmatisms. Each mineralization spots, however, has its own metallogenic features, likely representing diffident mineralization types. |
