POLLEN RECORDS AND CLIMATOSTRATIGRAPHY: A POWERFULTOOL FOR SHORT-TO LONG-DISTANCE CORRELATIONS OFCENOZOIC DEPOSITS
International audience Palynology contributes for long to stratigraphy, based on presence-absence of plant taxa (i.e., families,genera or species), a method severely thwarted by longitudinal and mainly latitudinal-altitudinal distributionof plants.Following pollen analysis applied to late Quaternary...

International audience Palynology contributes for long to stratigraphy, based on presence-absence of plant taxa (i.e., families,genera or species), a method severely thwarted by longitudinal and mainly latitudinal-altitudinal distributionof plants.Following pollen analysis applied to late Quaternary deposits, so successful not only for climatereconstructions but also for short-to long-distance stratigraphic correlations, we developed a similar approachfor the whole Cenozoic thanks to actual botanical identification of pollen grains based on their complete andrigorous morphological examination. Usually, identifications are provided at the genus level considering thatmost of the modern genera existed since the early Paleocene.The age of each studied exposed or drilled section is first determined using worldwide biostratigraphicmarkers (planktonic foraminifers, calcareous nannofossils, dinoflagellate cysts for marine sediments;micromammals for lacustrine deposits) and paleomagnetism.
