| 摘 要： | 本文应用了最新取得的“五统一”区域重力成果，并经过对浅表松散槽（如下辽河断陷，大岩体等）的密度亏损进行补偿改正后，求取了全省的区域重力场及其垂向二次导数，计算了莫氏面等深度图。在分析区域重力场及其垂向二次导数异常特征和莫氏面起伏特征的基础上，划分出辽宁深部构造的基本格局。从平面上探讨了深部构造与地形地势、地质构造及矿产分布的关系，从剖面上剖析了辽宁省地壳分层的宏观特征

| Abstract: | On the regional gravity achievement obtained recently and through compensation of density loss in shallow loose trough, the regional gravity field and vertical second derivative over the whole province were calculated, Moho depth contour sketch was drawn. The basic framework of deep tectonics in Liaoning was determined through analyzing the features of regional gravity field, vertical second derivative anomaly and moho rolling features. On plane, relationships of the deep tectonics with topography, geological tectonics and the distribution of mineral deposits were discussed and along sections the layering features of the earth crust in Liaoning province were indicated in the end. |
