摘要 从20世纪90年代初期开始,国内外学者开始探讨中国东部岩石圈从200km减薄至80~120km的机制、时限及过程。含金刚石及捕虏体的金伯利岩侵位于华北克拉通东部,提供了自古生代以来板内岩石圈地幔特征及其演化的深源岩石探针。本文综述前人对金伯利岩侵位年龄、同位素、流体包裹体、岩相学的研究,旨在提出金伯利岩在华北克拉通东部演化过程的研究意义,认为华北东部早古生代时含金刚石的金伯利岩侵位,表示当时存在冷、厚的克拉通岩石圈根,大陆克拉通的造陆运动是形成金伯利岩岩浆必要的大地构造背景。 Since the beginning of the 1990 s,domestic and foreign scholars began to explore the China from thinning of lithosphere in Eastern 200 km to 80 ~ 120 km,the mechanism and process of time.With diamond and capture xenoliths from kimberlites emplaced in the North China Craton through Eastern Paleozoic since the plate in the characteristics of the lithospheric mantle and the evolution of deep source rock probe is provided.This paper summarizes the former research of kimberlite emplacement age,isotope,fluid inclusion body,petrography,to the kimberlite in North China Craton through Eastern significance on the research of evolution and that in the eastern part of North China in the early Paleozoic containing diamond kimberlite emplacement,said there was cold and thick cratonic lithosphere root,carat,pass the epeirogenic movement is kimberlite magma necessary geotectonic background of the formation.
