在地球历史发展到距今2、3百万年以来的第四纪时期,全球气候起了重大变化,全世界曾有过广泛的冰川流行。古气候的变化也给庐山留下各种各样复杂的地质地貌现象,要认识几十万年前的庐山地质地貌现象该从何处下手呢?这正如我们要认识地球历史一样,应该从地层研究开始。对第四纪地质来说,应从第四纪沉积物的研究开始。李四光在研究第四纪冰川的过程中,曾不止一次地强调:“我所能引证的地貌证据在很大程度上是由沉积的证据所促使的。高山的毁坏程度是相当大的,若非更多地依靠和信赖沉积物
The global climate has undergone major changes in the history of the Earth to Quaternary times 2,3 million years ago, and the world has had extensive glaciers. Changes in paleoclimate also leave a variety of complex geology and geomorphology to Mount Lushan. Where should we start to understand the geological and geomorphological phenomena of Mount Lushan hundreds of thousands of years ago? Just as we should understand the history of the earth, The research started. For Quaternary geology, the study of Quaternary sediments should start. In his study of Quaternary glaciers, Li Siguang emphasized more than once: ”The evidence that I can cite is largely due to evidence of sedimentation, which is quite devastating, if not Rely more and trust more on sediments
