Cretaceous radiolarians of the southern South Atlantic

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...
