通过对近年新获得的各种地球物理和地质等资料的综合研究认为,羌塘西部隆起查桑段不是一个简单的、长期隆升的古隆起,而是总体由两三个东西向展布的大型南倾构造块体叠覆而成.此结构和地球物理特征,仅限于双湖-绒马之间,不具区域意义.其形成主要与该区东、西两侧中生代即发育近南北向转换断层、并与后期持续活动密切相关.该段挤压、叠覆和隆升始于早白垩世羌塘盆地反转期,与班公湖-丁青洋关闭相邻地块会聚直接有关;始新世以来,印度板块碰撞继续向北推挤,该区的挤压、叠覆又得到进一步的发展和改造.
Based on the comprehensive study of various newly acquired geophysical and geological data in recent years, it is concluded that the Chahanshan uplift in the western Qiangtang is not a simple, long-standing uplifted paleohigh but rather an overall distribution of two or three east-west Large-scale southern dip tectonic blocks are superimposed, and the structure and geophysical characteristics are limited to Shuanghu-Rongmao, with no regional significance.The formation is mainly related to the Mesozoic and near-North-South trending transitions on both east and west sides of the area Faults and are closely related to the later continuous activities.The extrusion, overlying and uplifting in this period started from the inversion period of the Early Cretaceous Qiangtang Basin and directly related to the convergence of the neighboring blocks of the Banghuhu-Dingqingyang closure. The Eocene Since the clashes in the Indian plate continue to push northward, the squeeze and overburden of the area have been further developed and transformed.
