摘要
华北岩石圈减薄是近十年来国内外研究的热门课题,但关于岩石圈减薄的具体时间、减薄幅度、空间分布范围、机制及其构造控制因素,多有争论。本文对上述问题进行了全面的回顾与讨论,内容包括:(1)是克拉通破坏还是岩石圈减薄;(2)古生代以来华北克拉通岩石圈地幔时代与壳幔解耦;(3)岩石圈减薄与克拉通破坏发生的时间;(4)岩石圈减薄的垂向幅度;(5)克拉通破坏在中国东部的空间分布;(6)克拉通破坏机制;(7)克拉通破坏的地球动力学原因;(8)华北克拉通破坏在世界上的特殊性等。文后,汇编了近10余年来华北岩石圈减薄与克拉通破坏研究的重要文献。
Lithospheric thinning and destruction of the North China Craton are intensively discussed in recent literature. It is unclear, however, about its time, thinning degree, spatial variation, mechanism and tectonic controlling factors for this kind of geodynamic phenomena. A comprehensive review and discussion is given in this paper, including: ( 1 ) Difference between lithospheric thinning and eratonic destruction; (2) Lithosphefic mantle ages beneath the North China Craton since Paleozoic and crust-mantle decoupling; (3) Time of the lithospheric thinning and destruction; (4) Vertical thining variations in the lithosphere; (5) Spatial variations in whole eastern China ; ( 6 ) Mechanism ; ( 7 ) Geodynamic controlling factors ; ( 8 ) Uniqueness of the destruction of the North China Craton on the Earth. Finally, a compilation of references on the lithospherie thinning and destruction of the North China Craton is given in the appendix.
