摘要
通过对西昆仑地震展布、新生代火山岩及塔西南转换波测深、晚期第三纪以来沉积等特征的分析研究,表明塔里木大陆岩石圈正往西南即西昆仑之下进行“A”型俯冲作用。最后,作者对“A”型俯冲的形成机理进行了探讨。
Abstract
By studing seismic spread and Cenozoic igneous rocks in West Kunlun, the detection of converted waves and deposit since the Late Quaternary in Southwest Tarim and other characteristics, it is revealed that Tarim continent lithosphere is subducting southwestward beneath West Kunlun in A-type subduction. At last, the forming mechanism of A-type subduction is discussed.
