【摘要】：正中生代是地球演化史上的一個重要時期,特別是晚中生代以來,全球發(fā)生了眾多重大的地質(zhì)事件,如Pangea古陸的裂解、大西洋的打開、華北克拉通破壞、印度與歐亞板塊碰撞及青藏高原隆升等,這些都已成為當(dāng)前國際地學(xué)界研究的熱點(diǎn)。近些年來,華北克拉通破壞的研究獲得了廣泛的關(guān)注�？死ǖ钠茐牟粌H表現(xiàn)在巨厚巖石圈的丟失和巖石圈地幔物理化學(xué)性質(zhì)的改變,而且還對地殼表層古地理、古環(huán)境和古生態(tài)產(chǎn)生了重要影響。目前,雖然大量
[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
