摘要
柴达木盆地南北地区,可以划分出两个巨型推覆构造带,分别称为柴北缘推覆构造带和东昆仑推覆构造带。其间的柴达木盆地形成一个相对的应变减弱区(低应变带)。两大推覆构造带在相同力源作用下统一构成了青海省北部的基本构造格局,成为华北板块的南部边缘带,是华北板块与南华板块碰撞拼合形成的浅部构造变形的产物,也是南北板块拼合的证据。
The northern and southern regions of Caidamu Basin can be divided into two huge nappe tectonic belts, namely northern Caidamu edge nappe tectonic belt and Eastern Kunlun nappe tectonic belt. The Caidamu Basin situated in between is a relativly lower strain area. These two huge nappe tectonic belts formed the basic tectonic pattern of northern region of Qinghai Province due to the action of the same force and became the southern edge parts of north China plate. They are shallow deformational products of plate collision and combination of north China plate and South China plate. Conseqently they are also the evidence of combination of north and south plates.
