【Abstract】 The author presents hete a mathematical method for calculating the isostatic subsidence of buried sea level indicators involved in their present altitudes by analysing the mechanism of isostatic movement caused by sea level rise in the coastal basin on the viewpoints of Mechanics and Earth Rheology. Based on this method,several ¹⁴C samples collected from a core in Jngjiang Estuary basin are calculated for their subidence caused by isostasy after burial.更多还原
