The Cretaceous-Tertiary Boundary (K-T) Interval in Badlands National Park, South Dakota

Philip W. Stoffer and USGS colleagues wrote this report (.pdf format) on the marine K-T boundary interval that occurs throughout the Badlands National Park region of South Dakota. Data from marine sediments (supported by paleontological correlation, sequence stratigraphy, magnetostratigraphy, and strontium isotope geochronology) suggest that several asteroid impacts may be preserved in the Badlands. The deposits are thought to represent late Maestrichtian events or possibly the terminal K-T event.
