Carbonate isotopes from the Canadian Arctic (Paleogene)

Ellesmere and Axel Heiberg islands in the Canadian Arctic Archipelago preserve terrestrial palustrine carbonate deposits spanning the late Paleocene to middle Eocene (59 to 45 Ma). Here we expand on existing regional stratigraphic, sedimentological and paleontological explorations through the addition of stable (δ13C, δ18O) and clumped (Δ47) isotope analyses on palustrine carbonates. δ13C isotope values range from -4.6 to +12.3‰ (VPDB), and δ18O isotope values range from -23.1 to -15.2‰ (VPDB).
