Elevation and subsidence rates of southeast coast crust obtain ed by littoral facies sediment samples
Abstract:The 490 littoral facies samples in carbon-14 in co ast areas of Fujian,Guangdong,Guangxi and Hainan since 45000 aB.P.are collec ted,and the rates of elevation or subsidence of coastal crust since Epipleistoce ne and Holocene has been determined based on the sea level change curve of type of progress step by step since 45000 aB.P.in Shiqi,Zhongshan city,Guangdong provin ce in this paper.The results show that besides some regions of the east and west of Gangdong aud Hainan,the partial area of southeast China coast al crust mainly appears to be subsidence in the early and late of Epipleistocene and Holocene,and it appears to be elevation in the middle and late of Holocene .The results of the deformation survey of recent crust are si milar to above-entioned conclusions.It is discovered that the 15 regions such as the east 60 km to Huilai country,Guangdong and Denglongsha in Pear River Delta are the high rate regions of the recent crust elevation or subsidence.
