| 摘 要： | 艾丁克罗赛岩体位于名的喀拉通克-南马克苏特铜镍成矿中基性岩带的中部，产于那林卡拉-吉木乃二叠纪叠加型陆相断陷火山盆地，形成于海西晚期后碰撞造山的陆内裂谷构造环境，区域成矿条件十分有利，通过岩石化学和稀土元素地球化学特征研究表明：它属于与铜镍成矿有关的岩体，并经历了较好的深部岩浆分异作用，其铜镍硫化物矿浆熔离作用强度虽比喀拉通克含矿岩体相对偏弱一些，但是仍具有形成比喀拉通克铜镍矿床相对贫化一些的块状硫化物铜镍矿体的成矿条件，而且不排除在其它地区史晚期的隐伏岩体形成较好的铜镍硫化物矿床可能性。

| Abstract: | The Aidingkeluosai body is just located in the middle part of the Cu-Ni-bearing intermediate-basic rocks belt in the famous Kalatongke-nanmakesute region, and situated in the superposed volcanic depression basin of the continental facies of the Permian Period in the Nalinkala-jimunai area. It was formed in the structural environment of the Late Hercynian land rift after the collision orogeny. So the regional metallogenic conditions are terribly favorable. That is indicated through the study on the characteristics of the petrochemistry and the REE geochemistry: the Aidingkeluosai body was related with the copper-nickel deposit, and it had undergone the better differentiation by the crystallization in the deep magma. Although the liquation of the ore magma of the Cu-Ni-bearing sulfide was weaker than the ore-bedring Kalatongke body, it was provided with the metallogenic conditions forming the Cu-Ni-poor ore body of the mass sulfide, and the Cu-Ni- rich sulfide larger-scale ore deposit may be formed by the later concealed intrusive body in other area. |
