| 摘 要： | 施雅风院士最近撰文指出笔者等近年来在中国东部发现的若干"冰臼"并非冰川遗迹,而是花岗岩经"负球状风化"而成。然而,他所谓的"负球状风化说"与当地的气候环境条件和客观存在的事实完全相悖。冰臼是地表负地形之一,现今是"堆积区"而不是"侵蚀区",以现代常见的侵蚀作用产生冰臼的所谓"风说"、"壶说"、"风雨说"、"差异风化说"、"负球状风化"等,都是不可能的。这些假说是对过去业己形成冰臼群进行不同成因推断,是对冰臼群成因的最大误解。冰臼只能由大量冰川融水沿冰川裂隙自上向下,以滴水穿石的方式形成滚流水钻,强烈冲击下伏基岩产生。从河流流水动力学特点上看,急流旋涡主要产生水平力为主,而冰臼的形成主要是垂直力才有可能产生,因此河流流水也是无法产生冰臼的。

| Abstract: | Academician SHI Yafeng recently published a paper titled Comments on the moulin argument provided by Mr.Han Tonglin,a misunderstanding of granite negative spheroidal weathering on the journal of Geological Review,related the origin of the glacial potholes,which found in eastern China by writer and others,to the so-called negative spheroidal weathering,instead of glacial traces.But the negative spheroidal weathering origin is in direct contrast to the Climatic environmental conditions and the facts.Glacial p... |
