K-T Boundary, Sr-87/Sr-86, Antarctica, Denmark

Scientific paper

Strontium isotope profiles, derived from minimally altered samples, across marine K/T boundary sequences exposed at Kjølby Gaard and Nye Kløv, Denmark, and on Seymour Island, Antarctica, show neither the boundary excursions, nor the boundary spikes, in 87 Sr/ 86 Sr that have been reported for K/T boundary sequences from elsewhere. Nor do our data conform to modelled predictions of the Sr isotopic response of the oceans to a positive spike in 87 Sr/ 86 Sr at the terminal Cretaceous. Boundary values for 87 Sr/ 86 Sr (with 95% confidence intervals) are in Denmark and in Antarctica. Our data suggest that 87 Sr/ 86 Sr stopped increasing and started decreasing at least 90 ka before the K/T boundary.
