Palaeogeographic analysis of the southern Anhui in the early Yanguan time of the early Carboniferous epoch
摘要
Abstract
The paleogeography has always been in doubt since the stratum of the early Yanguan time was determined in southern Anhui,where this paper asserts the existence of the Zhangbaling hills and the Jiangnan mountains and makes divisions of lake delta,lake marsh,shallow lake and deep lake,which reconstruct the paleogeographic environment features of that time.The sedimentary environment shows that the coal measures of the Leigutai Formation only develop in the lake marsh subfacies and lake delta subfacies,which are favorable to coal mining in the local areas.Clay deposits are concentrated in lake marsh subfacies and deep lake subfacies,and the quality of clay declines from north to south.关键词
