揭西、丰顺“冰臼群”成因商榷

A DISCUSSION ON THE CAUSE OF FORMATION OF THE POT-HOLE LANDFORM IN JIEXI AND FENGSHUN COUNITES,GUANGDONG

根据所谓冰臼群所处的地理位置及地貌部位， 提出由于广东不在高纬度和高海拔区， 第四纪时不具备冰川发育条件， 事实上也没有人发现有确切的冰川遗迹， 孑遗植物和热带、亚热带的生物群化石也佐证没有冰川出现过。据此， 我们认为所谓冰臼群， 实是河床壶穴地貌。

Guangdong Province is located at low latitudes where the mountains are low and far below the snow lines.There were no conditions for the development of paleo-glaciers and no remains of Quaternary glaciation have been discovered in Guangdong. This view point is also strongly supported by the survial plants from Quaternary glacial periods and the fossils of tropical and subtropical biota which also demonstrate the absence of Quaternary glacier in Guangdong. The so called “glacial mortars” are in fact the fluvial pot-holes developed on the river bed rock.
