| 摘 要： | 根据荣成后港泻湖和镆铘岛周围地区的勘察及S02孔岩芯样品的粒度1、4C、有孔虫等分析资料阐明了该泻湖的形成和演化过程,其形成于冰后期最大海侵之后(约7KaB.P.),泻湖的沉积速率约为0.8mm/a。对比得出,山东半岛的泻湖一般形成于最大海侵之后的两个时期,7KaB.P.左右和5~4KaB.P.;其沉积速率大多在1mm/a左右,最大可达1.56mm/a,最小的为0.55mm/a。泻湖的沉积速率大小主要与入湖物源有关,也与相对海平面升降,沉积物的压缩性相关联。

| Abstract: | On the basis of the field investigation in Hougang lagnoon and nearby Meye island area,this paper discusses the formation and evolution of Hougang lagoon which formed after the post-glacial maximum transgression,according to the data of core SO2 such as size of grain,~(14)C data,forminifera etc.Meanwhile,it follows by comparion that the lagoons in the Shandong peninsula commonly were formed in two time periods after the maximum transgression,namely about 7KaB.P.and 5~4KaB.P.and their sedimentation rates were about 1mm/a,the maximum being 1.56mm/a,and the minimum 0.55mm/a.The lagoons' sedimentation rate is mostly related to the matter sources entering the lagoons.Other factors,such as the relative sea level rise and the compressibility of sedimentation,also affected the sedimentation rate. |
