| 摘 要： | 通过分析鲁西隆起和济阳拗陷的地壳结构特征，结合二者的空间分布、时间演化及构造上的相关性，发现同处于伸展构造环境且相邻的鲁西隆起和济阳拗陷在地壳结构特征存在明显不同.济阳拗陷表现为地壳均衡的镜像结构特征，不同于地壳呈向上隆起状的鲁西隆起，说明鲁西隆起和济阳拗陷在成因上存在明显差异.济阳拗陷的伸展过程并非由地幔物质主动上涌造成，应是鲁西隆起在隆升过程对济阳拗陷地壳的拖拽作用，鲁西隆起和济阳拗陷的地壳结构特征反映出它们在成因上具有明显的耦合性.

| Abstract: | By analyzing the crustal structure characteristics of Luxi Uplift and Jiyang Depression, combined with the spatial distribution, temporal evolution and tectonic correlation, it is found that there are obvious differences between the two neighbors in terms of crustal structure characteristics though both are in extensional tectonic environment. The Jiyang Depression is characterized by mirror structure of isostasy, while the crust of Luxi Uplift is upheaved, indicating their distinct differences in genesis. The extension of Jiyang Depression is not caused by active upwelling of mantle materials, but should be dragged by Luxi Uplift during the uplifting process, which reflects the significant coupling in genesis as well. |
