摘要: 本文从青藏—蒙古高原东缘构造过渡带的布格重力场特征、地壳厚度和上地幔密度分布状态入手,就该带具有较统一的地球动力学背景的地球物理标志,壳-幔系统动力学模式及重力均衡调整等问题进行了讨论。

Abstract: On the basis of the features of Bouguer gravity field, distribution of crustal thickness and density of upper mantle in the transition zone on the eastern border of Qing-hai-Xizhang-Mongolian Plateau, the authors have discussed the geophysical signatures stemming from the same geodynamic background, the dynamic model of the crust-upper mantle system and the gravity isostatic adjustment in this transision zone.

Key words: Qinghai-Xizhang-Mongolian Plateau, Bouguer gravity -field, Crustal thickness, Density of the upper mantle
