| Abstract: | In this paper 34 terraces along 16 rivers in north Guangdong and at least 30 data of the 14C and TL ages of their alluvium are studied to understand their distribution and characteristics. There are at most 6 stages of river terraces in the region, of which the highest is 60m, 5~18m lower than that in west and east Guangdong; the deformation of the first stage terraces is the most evident: those at upper Lechang Gorge are normality terraces, at lower Lechang Gorge semi-buried terraces, and those at the reac... |
