| Abstract: | In this paper,mollusk and micropaleontological fossils(radiolaria,planktonicforaminifera,benthic foraminifera,Ostracoda)in four profiles respectively fromHeishigou and Beizhuang in Miaodao Islands and Daweijia and Yujaweizi in Jinzhou,Liaodong Peninsula have been primarily analyzed and their characteristics of combina-tions as well as the surrounding factors have been studied on the basis of analytic re-sults.1.The mollusk fossils and the distribution characteristics of the combination in thecoastal loess are mentioned.2.The combination characteristics and the law of distribution in the micropaleon-tological fossils in the coastal loess are expounded.3.The material sources of the coastal loess accumulations have been analyzed bymeans of organism fossil shells.4.By observing micropaleontological fossils,we have discussed distribution charac-teristics of coastal loess in different morphologic units. 5.We have studied paleoclimate change and sea level change through changes inquantitative distribution of the micropaleontological fossils in the coastal loess. |
