冰臼与壶穴之争述评OA
A REVIEW OF THE CONTROVERSY OVER THE QUESTION OF MOULIN AND POTHOLE
一些地质学家在粤东揭西和丰顺所发现的U形谷、冰碛物和石海等第四纪冰川遗迹的证据不足,该区成群出现的“冰臼”,实际上是河床基岩为河流侵蚀所形成的壶穴。控制壶穴形成的构造、岩性、地貌和河流作用等条件,文中作了较为充分的论述。粤西北封开—怀集地区已发现一系列第四纪冰川遗迹,因此广东的第四纪冰川问题,今后仍值得进一步研究。
Some geologists reported that U-shaped valleys,moulins,rock blockfield and other Quaternary remnants of glaciation had been discovered in Jiexi and Fengshun in Eastern Guangdong. But that has lack of evidence,and the so-called moulins occurring in groups in that area have been proved to be potholes in reality formed by fluvial erosion of the bedrock at river floor.This paper has dealt in some detail with the structures,lithology,geomorphology,fluvial process…查看全部>>
