摘要
Abstract
The author found the moulins swarms while surveying on regional geological minerals at the middle part of Inner Mongolia, the moulins of which are distributed at the flat top mountain with the altitude of from 2005 meters to 2033 meters and above the Mesozoic middle Triassic buff medium-to fine-grained monzonitic granite which is hard but no cleavage. Some circular moulins and irregular moulins are centralized distributed with the width of from 0.1meters to 1.2 meters and the depth of from 0.1meters to 0.3 meters. The wind direction can not effect that of the osculum and water flow erosion groove which had developed by the moulins. To compare with the surrounding moulins groups, we found that the moulin swarms over here have the higher altitude and small scale but complete shape with the obvious trace caused by water erode and flow, all of which show that they have the general characters of moulins. In general, the moulins were formed by the glacier erode and abrasive action at a long time of ice cover ablation. All above show that there are Quaternary glacier of a large scale which have the same characters with continental glacier, but we have to make the further research on the exact period and standing time as well as the distribution scale and the contrast with the world ice age.关键词
