Summary: Cretaceous radiolarians were recovered from subantarctic Atlantic calcareous submarine deposits from two of the seven sites drilled during ODP Leg 114 in 1987. Fairly well-preserved radiolarian assemblages were found in Hole 698A samples from the Northeast Georgia Rise, whereas assemblages with fair to good preservation were observed from Hole 700B in the East Georgia Basin. The assemblage compositions from both sites are rather low in diversity and are characterized by the dominance of Protoamphipyndax, Dictyomitra, and Stichomitra species, but lack zonal markers recognized from the midlatitude to low-latitude region. Assignment of a Maestrichtian age is based on co-occurring calcareous microfossils. This report constitutes the second such occurrence from the Atlantic sector of the Antarctic Ocean subsequent to the analysis of ODP Leg 113 materials from the Weddell Sea. (Auth.)
