on which series of regional climate and tectonic events can be established. In this paper
the deposit ages of lower terrace sediments along the major rivers were determined by TL dating along Xiaojiang fault zone. Comparing with the deposit age of the same level terrace sediment in the vicinity
the formed ages of the lower terraces surface were estimated
thus providing a chronological evidence for establishing the series of the recent clanate and tectonic events in the region concerned.
