Abstract
The data of Fe3+/Fe2+ show that the lowest annual air temperature of the Lushan, Huangshan and Tianmu mountains was not below 0°C, therefore, glacier couldn’t develop in these regions. According to palaeomagnetic test combined with the phenomenon of reticulate pattern ground and lithologic identification, the authors elaborate that the “Poyang moraine” is mainly the fluvial sediments of the early period of the Middle Pleistocene. It was formed by transportation of the ancient Ganjiang River under the humid hot climate. For CM image, the Dajiaochang profile of the Lushan Mountain is very similar to periglacial and the debris flow deposits, but the profile of Jiangpochang and Yaoshaling have many kinds of geneses, i.e., debris flow, water debris flow and alluvial etc. In the south piedmont of the Huangshan Mountain, slope gravity and slope seasonal running water transportation are mainly deposit factors. In the “glacial varve” of the Denglongqiao profile of the Tianmu Mountain, its CaO and Na2O content is lower than the nonglacial varve, the fact shows that it has the features of the violent leaching, weathering and nonglacial action.
