Revised stratigraphy of the Upper Cretaceous and Cenozoic series of Lebanon based on nannofossils

Abstract

The aim of these investigations was to revise the geological map of Lebanon. Calcareous nannofossils were studied from a predominantly marly Senonian–Maastrichtian and Cenozoic series. About 900 spot samples were collected from exposed strata. This lithologically homogenous stratigraphic interval is poorly subdivided on the existing geological maps. The present study allows the precise determination of hiatuses and tectonic events. Palaeocene, Upper Eocene, Upper Oligocene, and Lower Miocene units were identified for the first time in Lebanon.
