摘　　要：阜新盆地及邻区主要存在纬向系、北西系和新华夏系构造形迹,盆地经历了纬向系→早新华夏系→北西系→中、晚新华夏系的构造演化;纬向系奠定了盆地形成的基础,早新华夏系构成了盆地雏型,北西系是主要成盆构造,中、晚新华夏系是成盆后的主要形变构造。By means of the theory and methods of geomechanics,this paper analyzes the geological structure, structural systems and structural evolution of the Fuxin basin and explains the origin of the basin. There mainly exist features of the latitudinal structural system, Northwest structural system and Neocathaysian structural system in the Fuxin basin and its adjacent areas. Among them, the Northwest structural system may be divided into the early and late structural systems, and the Neocathaysian structural system includes the early, middle and late structural systems. They occurred in succession or alternation, overlapping each other to form the present structural framework of the basin. The latitudinal structural system originated earliest, and laid a foundation for the formation of the basin. It belongs to the pre-basin structure. The early Neocathaysian structural system gave rise to the embryonic form of the Fuxin basin. The Northwest structural system, the main basin-forming structural system, played a decisive part in the formation and development of the basin. The middle and late Neocathaysian systems essentially belong to post-basin structures.
