为了解山西断陷盆地及其邻区地壳内部物质迁移特征,基于山西地区1999—2008年重力场累积变化,采用考虑深度加权和模型粗糙度的反演方法,获得了地壳物质的密度变化。结果揭示了吕梁山区和临汾盆地中部地区地壳物质的累积,以及太行山与山西带中南部之间物质迁出的基本特征。
In order to find out the characteristics of crustal material migration in Shanxi rift and its adjacent areas, we got the crustal material density changes based on gravity variations from 1999 to 2008 in the area of Shanxi province, the weight with depth and flatness of the model are taken into account in the inversion process. The result showed the basic characteristic that material accumulation locates in the region of Lüliang Mountain and the middle of Linfen Basin, and material loss locates between the Taihang mountain and the centralsouthern Shanxi rift.
