时变重力测量确定青藏高原地壳隆升与增厚速率
|
Abstract:
联合绝对重力和重力反演与气候实验卫星（gravity recovery and climate experiment， GRACE）重力多年观测数据，获得了青藏高原多个基准站区域的地壳垂直形变速率。研究结果表明，绝对重力呈明显的负变化，绝对重力和卫星重力的时变系统差也呈较一致的负值，鼎新（DXIN）、德令哈（DLHA）、西宁（XNIN）、拉萨（LHAS）和仲巴（XZZB）5个基准站的区域地壳垂直形变呈明显的隆升状态，即拉萨块体、祁连块体和阿拉善块体处于地壳隆升状态，隆升速率分别约为2.01±0.15 mm/a、1.88±0.19mm/a、1.91±0.10 mm/a。在印度板块和欧亚板块的双向挤压下，青藏高原的地壳在不断的隆升与增厚，平均隆升速率约为1.94±0.17 mm/a，平均增厚速率约为2.35±3.30 mm/a
