摘要

The stratigraphic correlation of North and Equatorial Atlantic Ocean records with Mediterranean astronomically tuned sections reveals the diachrony of several planktonic foraminiferal bioevents, but shows the possibility to adopt the Mediterranean biostratigraphy in North Atlantic records. These data provide new tools for biostratigraphic correlation, mainly between the Mediterranean and the North Atlantic areas. Quantitative analyses carried out on planktonic foraminifera reveal the occurrence at Site 982-HoleB (ODP Leg 162) of some bioevents in the same order as those recorded in Mediterranean sequences. In addition, Neogloboquadrina atlantica praeatlantica first occurrence (FO) [within the short range of Paragloborotalia mayeri, sensuRiv. Ital. Paleontol. Stratigr.108 (2002) 257] occurs in levels older than its FO in the Mediterranean area where it first appears at the same level as N. acostaensis s.s. coinciding with the last occurrence of P. partimlabiata. In agreement with the findings of Poore [Init. Rep. Deep Sea Drilling Proj. 49 (1979) 447] and the hypothesis of Zachariasse and Aubry [Paleobios16 (1994) 68], the first representative of the neogloboquadrinids originated north of Iceland and migrated towards the southern latitudes at different times, first in the Mediterranean and mid-latitude Atlantic Ocean, then in low-latitudes (Site 397).
