阿孜巴勒迪尔岩体位于新疆西昆仑北坡库斯拉甫地区,对其进行了岩石地球化学特征研究,构造环境分析。研究结果显示,里特曼指数(σ)为1.37~2.17,属于亚碱系列;各岩类的主要岩石化学指数并未随着w(SiO2)的变化而有规律地变化,这表明各岩类属于不同源岩浆序列。岩石地球化学特征及各类图解表明,阿孜巴勒迪尔岩体为壳熔型岩浆,是晚华力西—早印支期造山带碰撞抬升到造山晚期的岩浆活动的产物。
The Azizar-Ledal rock mass is located in the Kuslaf area on the northern slope of Western Kunlun, Xinjiang, and is characterized by its geochemical characteristics and tectonic environment. The results show that the Rittman index (σ) is 1.37-2.17, belonging to the sub-alkali series. The major petrochemical indices of various rock types do not change regularly with the changes of w (SiO 2), indicating that the rock types Belong to different source magmatic sequence. Geochemical characteristics of rocks and various kinds of diagrams show that the Azizar-Daleir rock body is a shell-melting magma and is the product of magmatic activity from late collision or uplift of Late Verizoni- Early Indosinian orogenic belt to late orogeny.
