QUATERNARY GEOLOGY & GEOMORPHOLOGY

摘要：Enshi Bijiashan high altitude quaternary gravel layer shows multiple deposition cycles. Based on the study of the geographical location, sedimentology characteristics and sequence characteristics of the gravel layer, it is considered that the gravel layer is the cause of the proluvial. which belongs to the diluvial fan root subfacies and develops the characteristic support gravel. The relationship between the formation of the high — angle gravel layer and the uplift motion in the Quaternary system is discussed by comparing the gravel deposition cycle to the lift movement of the area since the Quaternary.
