摘要: 庐山位于江西省北部,北邻长江,南抵星子,东濒鄱阳湖,西达八里湖(图1),系一由其东侧的赣江断裂与其西侧的沙河断裂挟持而起的平均海拔为1,200—1,400米的断块山,主峰汉阳峰海拔1,474米。

Abstract: The red boulder clay, which was defined as the termini of Dagu Glaciation by the late geologist Li Siguang, is widely distributed in the shape of fan over the northwestern piedmont of Lushan near yangjiaoling. For half a century, there has been a different viewpoint that the boulder clay was not formed by glaciers.Through our field investigation and laboratory analysis of the boulder clay in it’s geomorphy,structure,fabric rock and mineral features,and spore-pollen components,it has been found that the boulder clay is extremely similar to the deposit of viscous debris flow, but utterly different from moraine, and that the climate was warm and wet during its deposition.It is concluded that the debris flow developed considerabely near Yangjiaoling of Lushan in a certain period of Quaternary, and the boulder clay was just a production of ancient debris flow.
