Abstract

A section recently exposed at Xilingang in the hinterland of the Pearl River Delta reveals that the fault-block movement is likely periodic or paroxysmal and not a continuous subsidence. Quaternary system of the section can be divided into 3 parts named as layer A, B and C from the bottom upwards. Both layer A and B are alluvial while layer C is aeolian and are OSL dated. The unconformable contact with a dip angle larger than 30° between layer A and B suggests a paroxysmal tilting and subsidence of basement fault-blocks after the formation of layer A. A relatively rapid uplifting of the Xilingang hill after formation of layer B is highlighted. The 3 layers are all cut off by a NNE trending normal fault with a fault-throw of 53cm, suggesting that the third paroxysmal movement of fault-blocks in the Pearl River Delta were occurred in recent epoch
