西秦岭北缘断裂带晚更新世晚期以来断裂运动的基本特征及运动机理

A Study on Movement Characteristics and Mechanism of the Fault Zone Along the North Edge of West Qinling Mountains Since Late Epipleistocene Epoch

本文根据大量野外地震地质调查资料和C^(14)年代数据,并结合青藏高原东北部震源深度、震源机制和地壳厚度资料,讨论了西秦岭北缘断裂带晚更新世晚期以来断裂的运动方式、运动强度、运动期次以及其运动机理等问题。

On the basis of abundant information from field seismogeological investigation, C14dating, combining the focal depth, focal mechanism of earthquakes and crust thickness in the northeast of Qing-hai-Xizang Plateau, this paper discussed the movement model, the movement intensity, the movement orders and the movement mechanism of the fault zone along the north edge of West Qinling mountains since Lata Epipleistocene Epoch.
