摘　　要：华北克拉通破坏或岩石圈变薄使得华北成为了研究大陆形成和演化的最理想区域,在该地区可以直接研究不同时代由深部岩浆捕获的地幔物质(捕虏岩或捕获晶)。特别是将它们与周围造山带的橄榄岩地块对比,可获得次大陆岩石圈地幔特性和地质历史过程中各段相互作用的重要信息。在华北克拉通之下的岩石圈地幔被破坏,使它成为了研究大陆形成和演化的理想区域。然而,破坏的机制、时间、范围和动力原因仍旧充满争议。在对比了与橄榄岩直接相关的岩石圈地幔特点的基础上,重点分析了克拉通复杂的破坏机理和岩石圈变薄的情况。North China Craton through destruction or lithospheric thinning of the North China become the formation and evolution of the research, the most ideal region, in the region can direct study of different times captured by the deep magma mantle material （ xenolith or capture crystal ） . Especially the subcontinental mantle lithosphere characteristics and geological history process segments are the role of important information to them and surrounding orogenic belt of the peridotite massif contrast. Under the North China Craton lithospheric mantle was destroyed, making it become the research, formation and evolution of the ideal region. However, the failure mechanism, time, scope and reasons of power are still full of dispute. Compared with peridotite directly related to the lithospheric mantle characteristics based, focusing on analysis of the carat through complex failure mechanism and lithosphere become thin.
