FOSSIL BEACH GRAVEL AS A RECORD OF SEA LEVEL CHANGE
Abstract:
The fossil gravels discovered in coastal zones of Qisha, Guangxi Province and Huangdaao and Feishaao, Zhejiang province are determined by their roundness, distribuion, relationship with around sediments, correlation of boring cores and 14C dating as records of high sea levels. Ages of these gravels as dated by wood contained in the gravels are Late Pleistocene and Holocene (36 200±200, 2588±129), so the gravels located approximately at the same altitude (2-4m) are different in age.
