通过对贝勒库都克一带花岗岩类的岩相学、岩石化学特征的详细研究,结合最新的大地构造学和地球化学研究资料,贝勒库都克序列中主要岩性有细中粒不等粒正长花岗岩,似斑状中粒含黑云正长花岗岩,似斑状中粒含黑云二长花岗岩,细粒正长花岗岩,似斑状细粒二长花岗岩。岩石化学总体上具有高硅、高铝、贫钙镁.贝勒库都克岩体明显富集Rb,Th,Ce,亏损Ba,Ta,Zr,Eu等元素。稀土元素含量较高,稀土元素配分模式呈较平坦的“V”字型体,地球化学以铕强亏损为特征;贝勒库都克花岗岩形成在碰撞,造山之后,相对稳定的环境。
Based on the detailed study of petrography and petrochemistry of the granitic rocks in Belleukurco area and the latest tectonic and geochemical data, the main lithologies in the Belleukurk sequence are fine-grained and irregular-grained The long granite, macular like plagioclase black granite is granite, like plagioclase granodiorite monzonitic granite, fine-grained granite, like porphyritic feldspar granite. Rock chemistry generally has high silicon, high aluminum, and poor calcium and magnesium. The Bayeruodundu pluton obviously enriches Rb, Th, Ce and depletes Ba, Ta, Zr, Eu and other elements. The REE content is high and the REE pattern is flatter than that of the “V” shape. The geochemistry is characterized by the strong depletion of europium. The Beilekuduke granite is formed in a relatively stable environment after collision and orogeny.
