摘要
///Whether there was a glacier on the Huangshan Mountains is a topic long in debate and the opponents take an advantageous position. One of the interpretations from the opponents is that the previous elevation of the Huangshan Mountains can not satisfy the condition of the hill being covered with snow all the year round. Such view point is from the interpretation of geographers for the mountain-building process of the Huangshan Hill without considering the information from the Huangshan massif and regional geology. Comparing the magma-originated depth and the recent crust thickness, it is reasonable to interpret that the crust of the Huangshan district has been thinned about 14~29 km since the late Cretaceous. Its geomorphic response is about 1.94~4.18 km . Accordingly, the elevation of the Huangshan at the late Cretaceous may have reached up to 2693~4776 m . Therefore, the Huangshan Hill is formed by differential erosion during the surface subsidence instead of by episodic rising.
