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...
