| 摘 要： | 北京西山的第四纪冰川遗迹考察和研究,始于20世纪50年代。但自80年代以来部分学者对有关冰川现象提出了异议,其中最主要的观点是有关现象可用冰缘气候下的雪蚀作用和寒冻泥石流作用给予解释。本路线介绍了可判识北京西山是否发育第四纪冰川关键的模式口冰溜面、管坨岭冰碛层、太平庄冰碛层、鲁家滩冰水沉积和大富庄冰碛层等五处第四纪冰川遗迹的古冰川宏观和微观特征。

| Abstract: | Quaternary glacial vestiges in the Western Hills,Beijing Municipality,have been investigated and studied from the 1950s on.However,since the 1980s,divergent views on the related palaeoglacial phenomena have been put forward by some geographers and geologists,whose main viewpoint is that the occurrence of the phenomena concerned can be explained by the nivation and solifluction in the periglacial climate.In this trip,the macroscopic and microcosmic features of the Quaternary glacial vestiges that are the key to judging and to understanding wheter the palaeoglaciers were developed in the following five visited localities:glacial pavement at Moshikou,Quintuoling till of the Guantuoing glaciation on the Guantuo Ridge,till of the Zhaojiatai glaciation in the west of Taipingzhuang,the glaciofluvial deposits of the Zhaojiatai glaciation in the north of Lujiatan Township and till of the Guantuoling glaciation in the east of Dafuzhuang. |
