摘要:
本文用14C样品年代测定资料讨论了辽东半岛全新世以来的海平面变化,并用数理统计法对5000年以来的地壳运动作了研究,发现与现代形变场的资料是一致的。说明现代地壳运动具有继承性。

SEA LEVEL CHANGES IN THE HOLOCENE ANDCRUSTAL MOVEMENT IN THE PAST 5000 YEARSIN THE LIAODONG PENINSULA
Abstract:
This paper discusses the sea level changes by the use of 14C dating in the Liaodong peninsula since holocene. Transgression took place in early holocene and the level was at the highest point in the past 5000-6000 years. A decrease in sea level was followed by the lifting of the Liaodong Peninsula. The crust movement of the land since 5000 years corresponds with the crustal deformation data in recent times.
