Strontium isotope stratigraphy and age model for CRP-2/2A, Victoria Land basin, Antarctica

first_imgStrontium isotope stratigraphy was used to date 16 discrete horizons within the CRP-2/2A drillhole. Reworked Quaternary (<1.7 Ma) and possible Pliocene (31 Ma) deposits below this boundary were cut by multiple erosion surfaces of uncertain duration. Strontium isotope ages are combined with 40Ar/39Ar dates,diatom and calcareous nannofossil datums and a palaeomagnetic polarity zonation, to produce an age model for the core.last_img
