在利用１∶５０ ０００ 高精度重力资料研究下辽河盆地南部地区的基底构造时，针对该裂谷型断陷盆地基底呈断距较大的破碎断块状格局和盆地下存在上地幔及下地壳隆起的地质构造特点，在分析了布格重力异常成因的基础上， 应用地震测深获得的地壳速度结构和１∶１ ０００ ０００ 的重力资料，成功地划分出深部地质因素产生的背景异常，并合理地进行了异常分离，从而获得了盆地基底和主要密度界面引起的区域异常。然后采用先二维再三维的重力模拟解释思路，确定了盆地基底的深度。
When using 1:50 000 high-precision gravity data to study the basement structure of the southern Liaohe River Basin, the basement of the rift-type fault basin shows a fractured block-like pattern with a large gap between the upper mantle and the lower crust Based on the analysis of the origin of the Bouguer gravity anomaly, the background anomaly produced by the deep geological factors is successfully divided by the crustal velocity structure obtained by seismic sounding and the gravity data of 1: 1 000 000 The anomalous separation was reasonably carried out and the regional anomalies caused by the basal and main density interfaces of the basin were obtained. Then using two-dimensional and then three-dimensional gravity simulation to explain ideas to determine the depth of the basins.
