Abstract:

Ostracoda faunas are analysed in the core NG931 sediments collected from the Great Wall Bay, Antarctica during 1992-1993. Totally 11 genera 21 species have been identified in the sediments, of which the most abundant is Loxoreticulatum fallax , the second abundant are Xestoleberis keguelenensis , Xestoleberis spp, Semicytherura spp, and Australicythere polylyca et al .. Most of them are the species of the ostracod fauna occurred in Antarctica area. Based on the study of ostracoda fauna from core NG931, the Holocene sedimentary environment is shore shallow sea.
