An Analysis of the Sediment Formation of the Quaternary Mudstone in the Mount Huangshan

Zhou Binggen, Li Gang, Wang Jiegui and Pan Lingling (Department of Geography, Anhui Normal University)  
There are a lot of the Quaternary mudstones in the Mount Huangshan. The characterestics of debris fabric at the typical sections show: AB plane and A axis trend to wards their headwaters; inclinations are bigger,——inclination of AB plane is about 36.0- 51.0 ° , and that of A axis is about 30-33.0° . The analysis of the deposit size shows that, the frequency curve of the deposit size takes in the form of double peaks; the accumulative curve is smooth; δ1 lies between 1.4-2.0; Sk1 nearly above 0, trending to be positive; and Kg lies between 0.678-0.788. The characterestics of the debris fabric and size of sediment show that the mudstone sediment of the Quaternary in the Mount Huangshan was neither the deposit of flowing water nor the glacial one. The sediment of mud-rock flow was formed by the common faction of the periglacial and interperiglacial environments of the monsoon-type.
