The River Terraces in Eastern Guangdong Province
详细信息   
摘要

    

55 terraces along 32 rivers in eastern Guangdong and 14C and TL ages from 25 samples are studied in this paper. There are at most 6 stages of river terraces in the region, of which the highest one is 70 m in height, and is distributed near present-day main riverbed. The first stage terraces include normality terraces, semi-buried terraces, and buried terraces, with decreasing ages. This indicates that the tectonic lift occurred earlier or the lift rate was faster in the areas of river head and the tectonic activity was gradually stabilized or sunk in the areas of mid-downstream. There are at least 12 sites where typical denude-plantation surface gravel layers were found.
