摘要
根据重力异常图等有关资料,研究了青藏高原均衡重力异常的分布特征与地质构造、地壳新构造运动间的关系,结果表明:(1)高原内各块体的均衡状态并不均一,而且异常幅值大小与地壳的相对隆起或沉降程度相关;
Based on the maps of isostatic gravity anomaly and relative data, the relations between isostatic gravity anomaly, geologic structures and strong earthquakes in Qinghai-Xizang plateau are discussed. The results show as follows:(1)The local diffrence of isostatic state is inhomogeneous, and the anomaly amplitute is relevant to the relative uplift or down of the crust.(2)The isostatic anomaly is closely related to the neotectonic movement and the strong earthquake distribution.
