摘要:

中国中部四川盆地和鄂尔多斯盆地与秦岭造山带构成盆山格局,特提斯洋的演化是该区盆山耦合的动力。印支—燕山期,强烈的逆冲推覆作用致使鄂尔多斯西缘贺兰山褶皱带和扬子古板块西缘龙门山造山带形成,并且形成了鄂尔多斯西缘和川西前陆盆地,构成了中国中部盆山耦合的格局。中部前陆盆地的形成经历了早期前陆拗陷盆地、陆内前陆盆地和再生前陆盆地变形三个阶段复合而成,从盆山耦合类型分析属于陆缘碰撞造山带与周缘前陆盆地。造山作用和前陆盆地之间具有统一的运动学过程和动力机制,造山带控制了前陆盆地形成演化过程。

Abstract:

Sichuan Basin and Ordos Basin are classic depositional basins in Central China,and constitute the orogeny-basin pattern with Qinling orogenic zone.The evolution of Tethys Ocean is the main drive of the mechanism.During Indosinian and Yanshan movement age,the obduction zone of Helan mountain in western Ordos margin basin and organic zone of Longmen Mountain formed,the thrusting and uplifting zone was formed by Qinqi orogenic zone,which caused the formation of foreland basins,and the frame of orogeny-basin was composed.The formation of the foreland basin is consisted of three stages:foreland depression basin formation stage,intracontinental foreland basin formation stage and regeneration foreland basin formation stage.The central foreland basin was continental collision orogenic belts and peripheral foreland basins.The orogeny and basin formation had same kinematics process and dynamic mechanism,and the orogenic belts controlled the formation process of the foreland basin.

Key words: basin-mountain coupling, foreland basin, Western Sichuan Longmen mountain, western Ordos margin
