The El Kef Section in northwest Tunisia is the Global Boundary Stratotype Section of the Cretaceous-Paleogene boundary. and Point for the base of the Danian Stage. The section has been studied in considerable detail since the 1980's and provides a remarkable record of the mass extinction event in a continental shelf setting. Sedimentation rates are rapid and this provides the opportunity for high-resolution studies of the mass extinction and subsequent recovery. Fossil preservation is known to be excellent. The outcrop section is somewhat weathered and difficult to sample, thus the coring project was designed to provide fresh material that could be sampled in considerable detail.
Our research program is based on four holes were drilled in December 2013 and January 2014. Professor Hedi Negra and Graduate Assistant Marwa Baroumi of the University of Tunis lead the geological characterization of the site and initial curation of the cores. Nejib Sassi of Geoconsil drilled the holes. We recovered core at four holes: Hole T, Hole A, Hole B, and Hole C.
The total of 160 m of cores were processed in the Bremen Core Repository, MARUM - Center of Marine Environmental Sciences, University of Bremen, where the science team convened for 5 days (Nov 17 - 21, 2014) to carry out data collection and sampling protocols similar to International Ocean Drilling Program projects.
