The geological significance of fossils in the coastal loess in the Bohai Straits and Liaodong Peninsula

摘要

Based on the analysis of the characteristics of the fossils (mollusks, Radiolaria, planktonic and benthic Foraminifera and Ostracoda) found in the four loess profiles located respectively at Heishigou and Beizhuang Villages on Daheishan Island in the Miaodao Islands in the Bohai Straits, and Daweijia and.Yujiawaizi Villages in Jinzhou County, Liaodong Peninsula, the distribution and abundance variation of the fossils in vertical profiles are studied, the source of coastal loess is probed and the relationship between loess deposition and paleoclimatic environment as well as sea-level changes is discussed.
