Chicxulub Target Stratigraphy and Ejecta: Insights from Northern Belize

David T. King, Jr., Lucille W. Petruny

Abstract

Laterally equivalent strata of the Cretaceous Yucatan Group, the target stratigraphic section of the end-Cretaceous Chicxulub impact event, occur in areas adjacent to Mexico, including northern Belize. In the absence of readily available subsurface data on lithologies within the Yucatan Group, it is a good strategy to use the relatively well known Cretaceous stratigraphic units, particularly the Yalbac and Barton Creek formations of northern Belize, as proxies for the analysis of provenance of carbonate clasts found within Chicxulub ejecta and crater-filling deposits.
