AbstractContourite drifts are recognized as able to generate mass-transport deposits along Portuguese margins. It is important to understand the behavior of these depositional bodies and to which external factors they may be related to. Calcareous nannofossil assemblages are here described as an additional proxy to identify and correlate these disturbed sedimentary units. Core CO14-GC-06 contains a combination of extant (e.g. Gephyrocapsa muellerae, Calcidiscus leptoporus s.l. and Coccolithus pelagicus s.l.) and extinct taxa (reticulofenestrids and watznaueriales) which relative proportions are related to the ongoing major oceanographic processes that generate marine paleoproductivity and reworking. A unique nannofacies, a reticulofenestrid-rich chalk, was detected on one of the turbidite layers, leaving the question of determining its provenance
