After reading the newly published article, entitled Comments on the Moulin Argument provided by Mr. HAN Tonglin, a Misunderstanding of Granite Negative Spheroidal Weathering (by Academician SHI Yafeng), the author of this paper collected a lot of materials and references to discuss the origin of potholes with Academician SHI Yafeng. The author disagree with Academician SHI Yafeng on the origin of potholes. Potholes are formed without being controlled by the joints in granites and without the participation of weathering, and thus, can not be interpreted with the socalled “negative spheroidal weathering”. Potholes can only be formed under the erosion of fast whirling water, and so the ones found on the granite ridges in the east of China can be treated as the meltwater erosion indicators of Quaternary glaciation. Recent observation on the abrupt draining of meltwater from the supraglacial lakes in Greenland provides important evidence for the meltwater origin of potholes. The arguments on the origin of potholes in China reveal the discordance of researchers on the development of Quaternary glaciation in the east of China. Apart from potholes, the Chinese researchers should pay more attention to other landform records related to Quaternary glaciation in the east of China. The socalled “Moulin Argument”, proposed by Professor HAN Tonglin, has improved the research on the landforms of Quaternary glaciation in the east of China.
