新疆北部克拉麦里—哈尔里克造山带是代表塔里木和西北利亚两个古大陆碰撞拼合部位的上古生代造山带。此带的侵入岩主要有钙碱性花岗岩类、辉绿岩岩墙、钾长花岗岩和碱性花岗岩等。它们侵入在泥盆纪—石炭纪岛弧火山沉积岩系中。 钙碱性花岗岩呈不同规模的岩基和岩株产出,岩石类型主要有含或不含角闪石的黑云母二长花岗岩和黑云母花岗岩,其次是石英闪长岩、花岗闪长岩和石英二长岩。研究表明,这些花岗岩是碰撞前在岩浆弧环境下形成的同熔型花岗岩,其年龄主要分布在368.4~312.1Ma之间。岩体中锆石的平均结晶温度为820℃。
The Kalamaili-Haerlike orogenic belt in the northern part of Xinjiang is a Paleozoic orogenic belt that represents the collision and assemblage of two ancient continents in Tarim and Northwest Asia. Intruded rocks of this belt are mainly calc-alkaline granites, diabase dikes, potash-bearing granites and alkaline granites. They invaded the Devonian-Carboniferous arc volcanic sedimentary rock series. Calcareous alkaline granite shows rock mass and rock production with different scales. The rock types are mainly biotite monzogranite and biotite granite with or without amphibole, followed by quartz diorite and granodiorite And quartz monzonite. The study shows that these granites were the same-melting granites formed in the magma arc environment before the collision, and their ages are mainly distributed between 368.4 ~ 312.1Ma. The average crystallization temperature of zircon in rock mass is 820 ℃.
