Refining the biostratigraphy and biochronology of the Belverde borehole (Setúbal Peninsula, Portugal): calcareous nannofossil data.

Research output: Chapter in Book/Report/Conference proceedingConference contributionpeer-review


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