Abstract:

Twenty marine sediment samples have been collected in the Quaternary sediments in the southwest deep-depression East Sea region to study the foraminifera’s characterization. By analyzing foraminifer components under a microscope and taking photos under SEM, the authors determined that foraminifera fossils in the research area belonged to 01 sub-ordo as per the classification system proposed by Loeblich A.R. and Tappan H., which is Globigerinina Delage and Hérouard, 1896 sub-ordo, including four families, ten genera and 24 species. 04 families are Globigerinidae (06 genera and 13 species), Globorotaliidae (with two genera and nine species), Pulleniatidae (one genus and one species), and Catapsydracidae (one genus and one species). They all belong to the planktonic foraminifer group, living in the deep sea. Their indicator ages range from Miocene to Recent.
