海平面变化研究中地壳均衡沉降量的估算

Estimates of isostatic subsidence in sea level variation studies

本文从力学和地球流变学的角度,分析海平面变化所引起的沿海沉积盆地水力-沉积均衡作用的机制,提出一种估算被埋藏的古海平面标志物的地壳均衡沉降量的新方法。

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 ^(14)C samples collected from a core in Jngjiang Estuary basin are calculated for their subidence caused by isostasy after burial.
