High latitude meteoric δ 18 O compositions from the Cenomanian Bastion Ridge Formation, Axel Heiberg Island, Canadian Arctic Archipelago: A palaeoclimate proxy from the Sverdrup Basin
Stable isotope analyses of a siderite-cemented siltstone from the Cenomanian Bastion Ridge Formation, Axel Heiberg Island, Canada, produce a range of δ 18 O values of -21.9 to -17 18.4‰ VPDB, and δ 13 C values ranging from 2.0 to 4.4‰ VPDB. A meteoric siderite line of -18.95 ± 0.33‰ VPDB is calculat...
