中国大陆东南缘晚中生代隆起山脉东界的确定

The Position of the Eastern Boundary of the Uplift Mountain Range in Late Mesozoic at the Southeastern Margin of Chinese Continent

木文利用东海和南海的勘探资料讨论了海域中生代沉积盆地的发育和分布特征,以及陆域和海域中生代中、酸性岩浆岩的发育特征,并以此为证据解决了中国大陆东南边缘晚中生代古隆起山脉的东界究竟位于何处这一悬而未决的问题,提出该隆起山脉的东界人致为东海海域和南海北部海域晚中生代沉积盆地发育区与剥蚀区之间走向NE的分界线。此外还根据花岗岩的成因环境和研究区的地壳厚度特征估算出此古山脉的隆起高度曾经达到大于4km,同时分析认为此山脉的构造属性并非安第斯山型。

Based on the expounding about the development and distribution of Mesozoic depositional basins with the investigative data acquired in the East China Sea and the northern South China Sea and studying the developing feature of intermediate and acid rocks in this continent and marine,the position of the eastern boundary of the late Mesozoic uplift mountain range situated at the southeastern margin of the Chinese continent has been resolved in this paper,which was a big problem that confused us for a long time.This eastern boundary of the uplift zone is roughly located at a strip area with NE trend between Mesozoic sedimentary basins and eroded regions in the East China Sea and the northern South China Sea.The height of this ancient mountain zone attained ever to greater than 4km by analyzing the origin environment of granite and the thickness of the crust around the research area.And the cognition that the tectonic character of this mountain range does not belong to Andean Mountains has been acquired.
