摘　　要：本文利用深部地球物理资料研究了扬子板块内部四川、江汉、苏北三个中新生代盆地的深部地质构造,指出这三个盆地深部壳幔岩石圈结构和构造特征与“东西锋线”作用有关,且决定了现今的盆地构造展布状况。Based on the deep geophysical data acquired,a review is made with regard to the deep geological structures of three Meso-Cenozoic Sichuan,Jianghan and Subei Basins,which are developed in Mid-Plate setting. It is suggested that the deep crust-mantle's lithospheric architecture and structural features of the three basins are related to the action by 'two fronts'(Z. X. 1979[14]). Also,the distribution of existing basins'structures is controlled by it.
