Pleistocene radiolarians from the Leg 119 Site 745, sections (1H to 4H) in the southern ocean region

  • Published:
Journal of the Geological Society of India

Abstract

This paper presents a detailed record of radiolarian species from the Leg 119 Site 745 (sections 1H to 4H) in the southern ocean region. Forty five species were identified and illustrated from forty six samples. The taxonomy, two radiolarian zones namely NR1 and NR2, morphological variations and distribution of taxa have been made from these sections. Twelve new species are identified but they are not formally named. The study provides the detailed Antarctic Pleistocene radiolarian data, proposed the placement of NR1 and NR2 zonal boundary at a shallow depth of 6.63 mbsf and data is used for comparative studies with other parts of the Antarctic region.
