Dmitrenko, O. B. (1998): Distribution of calcareous nannoplankton of the Rio Grande Rise during the Neogene (the South Atlantic Ocean, Site 516). MAIK Nauka/Interperiodica, Birmingham, AL, United States, Oceanology, 38 (3), 381-393, georefid:1999-029234
Abstract:
Calcareous nannoplankton from 44 samples of a thick (169.5 m) Neogene section of site 516 drilled by the D/V Glommar Challenger in the South Atlantic was studied. More than 60 species were determined. Distribution of these species along the section allowed us to establish the availability of eight biostratigraphic subdivisions of schemes of E. Martini (NN) and D. Bukry (CN): NN2 (CN 1c)-NN18 (CN12a). In the middle of the Middle Miocene and in the end of the Late Cretaceous-beginning of the Pliocene, two periods of stratigraphical gaps were noted in the section. They have a local nature and are only partly determined in adjacent drilling sites at the Rio Grande Rise.
