用大地测量资料检验青藏高原隆升的两种构造演化模式

A Check on the Two Tectonic Evolution Models for the Uplift of Qinghai-Tibetan Plateau by Using Geodetic Data

摘要: 对当前地质学和地球物理学方面提出的两种青藏高原构造演化模式进行了分析,着重讨论了用大地测量资料检验构造演化模式的原理和方法,以实测资料初步验证了回流模式的合理性。

Abstract: This paper discusses the differences between bsckflow model and squeeze model,which are two typical tectonic evolution models in the Qinghai-Tibetan Plateau,presented by geophysical and geological communities in recent years.The principle and method for checking these models with geodetic data are given.The check has been conducted by using real data.It turns out that the backflow model is more reasonable than the other one in the sense of dynamic mechanisms of tectonic evolution in the Qinghai-Tibetan Plateau.
