【摘要】：正中生代是地球演化史上的一个重要时期,特别是晚中生代以来,全球发生了众多重大的地质事件,如Pangea古陆的裂解、大西洋的打开、华北克拉通破坏、印度与欧亚板块碰撞及青藏高原隆升等,这些都已成为当前国际地学界研究的热点。近些年来,华北克拉通破坏的研究获得了广泛的关注。克拉通的破坏不仅表现在巨厚岩石圈的丢失和岩石圈地幔物理化学性质的改变,而且还对地壳表层古地理、古环境和古生态产生了重要影响。目前,虽然大量
[Abstract]:The Mesozoic is an important period in the history of the Earth's evolution. Especially since the late Mesozoic, there have been many major geological events in the world, such as the disintegration of the Pangea ancient land, the opening of the Atlantic Ocean, and the destruction of the North China Craton. The collision between India and the Eurasian plate and the uplift of the Qinghai-Xizang Plateau have become hot spots in the current international geosciences. In recent years, Extensive attention has been paid to the study of the North China Craton failure, which is not only reflected in the loss of the extremely thick lithosphere and the change of the physical and chemical properties of the lithospheric mantle, but also in the paleogeography of the crust surface. Paleoenvironment and paleoecology have had important effects. At present, although a large number of
