| 摘 要： | 中国东部中、新生代伸展构造系包括由松辽盆地、华北盆地和江汉盆地等构成的裂陷盆地 ,以及由大兴安岭、太行山及雪峰山等构成的伸展山岭。从大陆裂解和伸展构造动力学来看 ,主要存在底侵作用、对流作用和拆层作用 3种机制。因此裂陷盆地与伸展山岭耦合关系主要是深部壳幔作用在浅层的响应。

| 关 键 词： | 裂陷盆地 伸展山岭 底侵作用 对流作用 拆层作用 |

| Abstract: | The Mesozoic-Cenozoic extensional tectonic system in eastern China is composed of rift basins and extensional mountain system. There are three typical couples: Songliao rift basin and Great Xing'an mountains in the northern part, the North China rift basin and the Taihang mountains in the middle, and the Jianghan rift basin and the Xuefeng Mountains in the southern area. The underplating, convecting, and delamination are the three major mechanisms in the continental rifting and extensional geodynamic system. The coupling of rift basin and extensional mountain system is the effect of evolution of the interaction of crust mantle boundary. |
