Hover over images to reveal the KPg boundary

This website contains a documentation of subjects I am professionally interested in.
A major goal of this site is to provide a complete documentation (in progress!) of all KPg boundary (here) localities in the world.

The only complete documentation of KPg boundary interval of the ICDP-CSDP drill core Yaxcopoil-1 in the Chicxulub crater, with all the images of the core boxes; the sampling and sample division of the transition suevitic ejecta-backwash-seiche-lowest Paleocene.

The site will provide a data dump of all the data I have generated in my professional past. Everyone is free to (per) use these data (published and unpublished) as they see fit (with acknowledgements ofcourse!).

Controversies and debates that have raged over the years, and most are still going on. Science in action!
