Abstract

In this paper, we present a combined study of planktonic foraminifera and calcareous nannofossils that refines the previously established stratigraphic framework of the Belverde Borehole (Portugal). For the first time, some of the classic Miocene lithostratigraphic units of the Lower Tagus Basin are correlated with calcareous nannoplankton standard biozones: the top of unit IVa-NN3; units IVb, Va1, Va2, Va3, Vb, and Vc-NN4; unit VIa-NN5; unit VIb-NN6; units VIc and VIIa, b-NN7 or later.
