摘要
为了有效保护地质遗迹,并开展地质科普教育,避免以讹传讹,本文针对大别山南麓湖北省罗田县河铺镇与九资河镇交界处所发现的"冰臼群"进行了调查和研究。通过对"冰臼群"分布和形态特征分析,认为大别山地区河谷中的"冰臼群"系由水流侵蚀作用形成,其分布受构造(节理)控制,其改造和破坏受河流下切作用的强烈影响。因此,该"冰臼群"是流水侵蚀成因的壶穴而非冰川成因的冰臼。从目前的证据看,大别山地区并不存在第四纪冰川。
In order to protect the geological relics effectively and carry out geological science education, avoid baseless assertion, this paper investigated and studied the newly found "ice moulins group" at the southern Dabieshan area, which is the boundary area of Hepu Town and Jiuzihe Town of Luotian County, Hubei Province. Based on the analysis of the distribution and features of the "ice moulins group", the authors considered that the "ice moulins group" in the valley of Dabieshan area is formed by the erosion of the stream. The distribution of the "ice moulins group" is controlled by the joint system and its rebuilding and destroying are strongly effected by the stream downcut. Consequently, the so-called "ice moulin" is actually the pothole formed by the stream erosion rather than the quaternary glaciation in Dabieshan area.
