位于山东半岛东端港湾曲折的(石章)壁海岸,有一些大小不等、形状各异的泻湖,其中有些是理想的海洋水产养殖基地;有些是良好的船舶港域;有些还可以为研究古代泻湖沉积提供对比资料。为了探讨这类沉积的环境特征,作者对荣成湾海岸泻湖进行了调查和室内分析。一、区域地质地貌概况荣成湾海岸泻湖位于中朝古陆胶东地盾东南部城厢-俚岛地堑内。北部是一片第四纪海积层和冲积层,现已高出海面;西部和南部是白垩纪的青山组和太古界的胶东群,它们构成
Some of the lagoons of varying sizes and shapes, some of which are ideal marine aquaculture bases; some are good shipping harbor areas; some are also suitable for research purposes Ancient lagoon sediments provide contrast information. In order to investigate the environmental characteristics of these deposits, the authors conducted a survey and laboratory analysis of the Rongcheng Bay coast lagoon. I. Introduction to Geology and Geomorphology The Rongcheng Bay coast lagoon is located in the Chengxiang-Sengjian Graben, southeast of the Jiaodong East Shield of the Sino-North Korea. The north is a Quaternary sea layer and alluvium, is now above the sea; western and southern Cretaceous Qingshan Formation and Archean Jiaodong group, which constitute
