The main quantitative indicators include uplift amplitude of the Moho, Quaternary and Late Holocene coasts. The paper also gives a brief account of the research method on quantitative indicators of surface uplifted zones. Taiwan is a famous neotectonic zone and an area of large earthquakes in the world. There is only one large-earthquake area in each of Fujian, Guangdong and Hainan Provinces. Along the coast large earthquake areas there are certainly many remains of crustal activity. Among these remains, coast activity, taking the sea level as the accurate marker horizon, can determine not only the amplitude of coastal elevation and subsidence in a certain period, but also the cycle and rate of positive or negative movements.展开更多

They were found in the late Holocene high beachrock of 25--m ele-vation on Longhu Hill of Houshijing, Pinghai Village, Putian County, Fujian Province. Theseanimal remains are found mostly between intertidal and subtidal zones in the tropical areafrom the Miocene to the recent. The research results have confirmed that the coastal sedi-ments belong to the beachrock, which is formed in the tropical coastal areas. This paperproposes that the study of large animal remains in the beachrock can provide a scientificbase for the understanding of the sedimentographic environment of the beachrock, andvaluable information for the study on paleoclimate and paleo-shoreline evolution.展开更多
