New biostratigraphic data on the Paleocene-Eocene from the Prebetic

A biostratigraphic study of the Paleocene-Eocene of the stratigraphically continuous with the northern foreland (Iberian Meseta), Prebetic has been studied by using planktonic foraminifera, calcareous nannoplankton, and larger benthic foraminifera. Twelve sections have been studied along the chain: four sections in the Alicante Sector, four in the Murcia Sector, two in the Granada Sector, and two sections in the Jaén Sector.

The Paleocene-Eocene Prebetic succession can be divided into three stratigraphic formations related by lateral and diachronic changes of facies: limestones and calcarenites (rich in larger benthic foraminifera) in middle stratigraphic position, and two marly-clayey formations in lower and upper positions, respectively. The middle unit represents an internal marine platform, while the two marly-clayey represent the external platform (and the upper slope in a few cases). As a whole, above the unconformity, representing the missing interval which includes the Cretaceous-Paleocene boundary.
