摘　　要：喀拉通克岩浆型硫化铜镍矿床产于新疆北准噶尔褶皱带。含矿岩体具有低ＴｉＯ２、高Ｋ２Ｏ、轻稀土富集以及亏损高场强元素的特征，与岛弧钙碱性玄武岩浆的微量元素特征相似。岩浆作用产生在西伯利亚板块和准噶尔板块碰撞后开始拉张环境，继承了岛弧岩浆作用的特征。The Kalatongke magmatic Cu-Ni deposit is situated in the northern Junggar orogenic belt. The host intrusion is characterized by the depletion of TiO2 and high field strength elements and the enrichment of K2O and light REE, similar to island-arc calcalkaline basalts. It was formed in an extensional environment developed after the collision between Siberia and Junggar continental plates, inheriting the features of island-arc magmatism.
