Title: THE BASIN-MOUNTAIN COUPLING RELATION IN THE FORELAND BASINS IN CENTRAL CHINA
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.
