东南亚中南半岛与中国西南邻区地层分区及沉积演化历史

本文通过对东南亚中南半岛的缅甸、泰国、柬埔寨、老挝、越南五国及毗邻的中国西南地区地层的对比研究,依据研究区构造演化、沉积岩石组合和古生物群特征将整个区域划分为5个地层分区:冈瓦纳型的印度地层区、过渡型亲冈瓦纳的滇缅马地层区、过渡型亲华南的印支地层区、属劳亚大陆的扬子地层区和华夏地层区。论述了地层区的基本特征,并进一步对各地层区间做了沉积演化对比,进而阐明了区域的重要构造事件与洋盆沉积演化历史。

Stratigraphic zoning and tectonic events in Indochina and adjacent areas of southwest China
