关于东天山花岗岩与陆壳垂向增生的若干认识
Some problems on granites and vertical growth of the continental crust in the eastern Tianshan Mountains, NW China
-
摘要: 东天山海西期主碰撞以后形成的花岗岩可分为三个阶段:挤压.伸展转折阶段(310~285Ma)、碰撞后伸展阶段(285-250Ma)和板内阶段(250-208Ma)。这三个阶段在岩石圈厚度、等温线形态和动力学状态等方面的差异,造成了不同阶段花岗岩岩体形态、岩石组合、岩相学和地球化学等方面的差异。除了底侵以外,幔源岩浆的内侵可以造成地壳不同层次岩石的部分熔融,也是花岗质岩浆生成的重要机制和地壳垂向增生的重要方式。东天山的片麻状花岗岩有一部分是变质交代成因的,这类花岗岩的形成与碰撞后幔源岩浆的底侵和内侵有关。变质峰期后韧性剪切带中构造细粒化的岩石是形成片麻状花岗岩的最有利部位。虽然这类花岗岩多数定位于地壳较深层次,但在内侵热量的影响下也可以定位于较浅层次。康古尔韧性剪切带的形成除了构造动力作用以外,还与地壳垂向增生,尤其是内侵有着密切联系,是构造动力、岩浆活动、变质作用和流体运移等复杂反馈的结果。博格达造山带碰撞前和碰撞后岩浆岩均具有正的εNd(t)值,表明该造山带地幔早在碰撞前就已亏损,而碰撞后的地幔则继承了碰撞前地幔的亏损特征。东天山在印支期有一次重要的地壳垂向增生事件,其岩浆活动和成矿作用与古特提期洋的俯冲和随后的碰撞密切有关,因此是东天山从中亚构造体制向特提斯体制转换的产物。
