The paper presents a first comprehensive account of Pleistocene radiolarians from a Piston core KH94-4- AMR-2PC in the Antarctic continental margin of the Southern Ocean region. Seventy five well preserved radiolarians from the fifty four samples were identified. The study shows that the section lies in the Chi Zone. This zone is further subdivided into lower and upper Chi subzones on the basis of last appearance, consistent appearance and highest common appearance.Twenty five new species were encountered and described but they have not been formally named. Minor reworking is observed in the studied sequence.

Abstract


The paper presents a first comprehensive account of Pleistocene radiolarians from a Piston core KH94-4- AMR-2PC in the Antarctic continental margin of the Southern Ocean region. Seventy five well preserved radiolarians from the fifty four samples were identified. The study shows that the section lies in the Chi Zone. This zone is further subdivided into lower and upper Chi subzones on the basis of last appearance, consistent appearance and highest common appearance.Twenty five new species were encountered and described but they have not been formally named. Minor reworking is observed in the studied sequence.
