中国陆内造山带造山过程地球动力学分析

GEODYNAMIC ANALYSIS ON THE OROGENIC PROCESS OF INTRACONTINENTAL OROGENIC BELTS OF CHINA

本文论证了我国陆内造山带岩石圈结构、造山过程岩石圈浅层变形构造样式、盆山变形构造时空耦合关系、造山过程与沉积盆地变形动力学模式等。提出中国西部造山带造山过程岩石圈变形总体是：上部以伸展变形为主，中部以挤压变形为主，下部以伸展变形为主。通过中国造山带造山过程与沉积盆地变形作用时空耦合关系对比研究，首次建立起造山过程与沉积盆地形成时空耦合关系的三类四型动力学模式：单向楔入造山推覆成盆、双向楔入造山推覆成盆、剪切造山反转成盆和伸展造山断陷成盆模式。

The emphasis of this paper is placed on the lithospheric texture,structural styles,spatial and temporal coupling relationship between orogenic belts and basins,and dynamic models of orogenic process and sedimentary basins in the intracontinental orogenic belts of China.Three type and four pattern dynamic models for the spatial and temporal coupling of orogenic belts and sedimentary basins have been established.These models include unidirectional wedge in orogenesis and thrust induced basin,bidirectional orogenesis and thrust induced basin,shear orogenesis and reversed basin,and detachment orogenesis and rifted basin.
