摘    要:北祁连山是中国研究古板块构造和俯冲带的经典地区,肖序常先生在此进行了开创性的研究工作。该俯冲带记录了490~440Ma的高压变质年龄,是目前世界上最老的大洋冷俯冲带之一。较系统地总结了北祁连造山带的研究历史、近年来在高压变质岩及相关岩石研究领域的最新进展,并根据详细的矿物学、岩石学、地球化学和同位素年代学资料,对本区大洋扩张、俯冲和大陆碰撞造山的构造演化过程进行了新的透视和评述。

关 键 词:高压变质岩  大洋冷俯冲带  早古生代  北祁连山

Abstract:The North Qilian Mountain range is a typical region for paleo-plate tectonics studies in China, and Prof. Xiao Xuchang carried out some innovative works in this field. This orogenic belt is one of the three oldest cold oceanic subduction zone so far recognized in the world with a subduction history from 490 Ma to 440 Ma in rock record. In this paper, we have systematically summarized the research history in North Qilian orogenesis as well as new progresses in terms of high-pressure metamorphic rock and other rock fields during the recent years. By means of detailed mineralogical, petrologic, geochemical and geochronological studies, we've also put forward some new perspectives and review on the tectonic evolution of the North Qilian orogenesis in terms of ocean expansion, subduction and collisional orogeny.
Keywords:high-pressure metamorphic rocks  oceanic cold subduction  Early Paleozoic  North Qilian Mountain
