沙漠沙海是现代和古代全球环境的一个重要组成部分。其同期形成的岩层含有重要的油气矿床,同时还是极好的含水层。沙漠的变迁导致了古代文明的衰落与淹没以及成为当今沙漠边缘大草原区(Sahel)的灾难。然而,对沙漠所进行系统的研究仍是寥寥无几,中新世至今的沙漠史仍是一片空白。本文阐述了对炎热低地沙漠尤其是南非的最新研究,侧重于重建古环境和古气候。
Desert Sand Sea is an important part of the modern and ancient global environment. The formation of the same period of rock contains important oil and gas deposits, but also an excellent aquifer. The vicissitudes of the desert led to the decline and overwhelming of ancient civilizations and the disaster of today’s savannah on the edge of the desert. However, there are still few systematic studies on the desert and the history of the desert from the Miocene to the present remains a blank. This article presents the latest research on the hot deserts, especially South Africa, focusing on the reconstruction of paleoenvironment and paleoclimate.
