本文主要研究内容
作者王国灿,张攀(2019)在《蛇绿混杂岩就位机制及其大地构造意义新解:基于残余洋盆型蛇绿混杂岩构造解析的启示》一文中研究指出:蛇绿岩代表了古洋壳的残余,通常被作为识别古汇聚板块边界的重要标志之一.但是,通过对西准噶尔造山带和松潘-甘孜造山带内出露的蛇绿混杂岩的大比例尺填图和构造解析,揭示出并非所有的蛇绿混杂岩带都具有缝合带的大地构造意义.综合前人研究结果,将蛇绿混杂岩划分为缝合带型和非缝合带型2种类型.非缝合带型蛇绿混杂岩带的分布与残余洋盆在闭合过程中的构造过程密切相关.在残余洋盆被巨厚层的碎屑岩填充之后,作为残余盆地基底的大洋岩石圈物质在区域挤压应力作用下,可通过多种形式构造就位于上覆碎屑沉积地层之中,形成具有弥散性分布特点的残余洋盆型蛇绿混杂岩系统.而缝合带型蛇绿混杂岩的就位过程可划分为3种方式,分别是俯冲就位、仰冲就位和碰撞就位.这些不同类型的蛇绿混杂岩带在板块汇聚后的再造山过程中,早期的构造变形会被叠加改造甚至导致蛇绿混杂岩的重新就位,使其分布形式复杂化.因此,正确识别和厘定不同构造过程形成的蛇绿混杂岩带及其对应的大地构造背景,对研究洋陆转换过程和造山带的演化至关重要.
