祁连造山带研究概况——历史,现状及展望

回顾了祁连造山带的研究历史，对研究现状作了简要总结。认为在祁连造山带已初步建立起岩石圈结构及动力学模型，划分了板块构造单元，祁连山自震理纪以来先后出现大陆裂谷和板块构造两种构造体制及三种不同类型的造山作用（俯冲造山，碰撞造山和陆内造山）而构造体制变更，盆地类型转换以及造山作用类型变化的地球动力学机制是地幔柱构造。提出了造山带研究现存在的关键问题，对未来的研究进行了展望，作者认为祁连山造山理论的研究

INVESTIGATORY SUMMARY OF THE QILIAN OROGENIC BELT,CHINA:HISTORY, PRESENCE AND PROSPECT

This paper outlines the study history of the Qilian orogenic belt and summerizes its present study situation.The author believes that the lithospheric texture and dynamic model of the Qilian orogeric belt have been basically established.The Qilian Mountain has been found to be composed of different tectonic units and subtectonic units which have undergone two different tectonic systems since Sinian,called continental rifting and plate tectonics.The orogenesis is characterized by subduction,collision and intracontinental convergence,which were all dominated by mantle plume tectonics.The paper also points out some of the key problems of the present study on the orogenic belts and the study prospects in future.
