Comments on the Moulin Argument Provided by Mr. Han Tonglin,a Misunderstanding of Granite Negative Spheroidal Weathering

详细信息   
摘要

This 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. The author believed 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.
