Detailed stratigraphic and sedimentologic analysis of the main oil-producing stratigraphic interval at the Cantarell Oil Field suggests a general graded stratigraphic architecture for the Cretaceous-Tertiary (K/T) boundary carbonate sedimentary succession. Extensive well log data, core description and petrographic analysis, as well as comparison with contemporaneous outcrop analogs, indicate that this interval is dominated by a thick carbonate breccia genetically related to the Chicxulub meteorite-impact event occurred in northern Yucatan. The carbonate breccia deposit is consisting with a base-of-slope apron.
