Stratigraphic Transect of Northwestern Colombia: a Key to Understanding the Origin of the Panamanian Isthmus

Abstract:

We present new data on the stratigraphy of the Miocene in northwestern Colombia, in the Pacific Basin. The sedimentological and biostratigraphic study, based on an analysis of calcareous nannofossils, foraminifera, palynomorphs, and diatoms, has enabled a new framework to be constructed that allows the closing process of the Isthmus of Panama to be monitored and palaeoceanographic implications to be made.
