摘要: 提要:本文概要总结了羌塘地体内部的双湖—冈玛错—龙木错构造带地质与地球物理特征。从地表出露的蓝闪片岩、混杂堆积和生物古地理特征的差异,以及重力异常带分布、Pn波异常特征及地震层析成像等可以看出,双湖—冈玛错—龙木错构造带很可能是冈瓦那大陆和欧亚大陆之间的缝合带。Abstract: Abstract:This paper has summarized the geological and geophysical characteristics of the Shuanghu-Gangmacuo-Longmucuo structural belt in Qiangtang. The blue schist, mélange, gravity anomaly,Pn wave anomaly and seismic tomography image show that the Shuanghu-Gangmacuo-Longmucuo structural belt may be a suture between Gondwana plate and Asia-India plate
