Abstract: In a book tilted “Moulin Discovered” (English version), Mr. Tonglin Han classified all small granite potholes, hollows and depressions developed along the joints as moulins. He recognises all these moulins are the relict landforms of paleoicesheet and deducted that all moulins were formed by global panicesheets occurred 2~3 million years ago. The present paper, based on the abundant photos and descriptions of these moulins from Han's book, together with comparison with literatures, argues that moulins, commonly occurred at deadice region as potholes, are rare in glacial regions. This type of potholelike landforms in the scales between centimeter and meter should be the results of negative spheroidal weathering in granite rocks, and related to the geological structure of joints and cowork of winds and water dynamics. Thermoluminescence dating on some materials from the bottom of the moulins indicates that these deposits are younger than 10 ka of the postglacial age. Han has forcefully spreads his wrong “moulin” theory, which has misled readers to blindly believe larger distribution of Quaternary glaciers in China, influenced some tourism administrations setting up numerous sites as Quaternary glacier sceneries, and has wrong affected our social cultures today.
