Deep drilling of the Chalco Basin, Valley of Mexico
~800,000 year record of North American climate
Scientific drilling project to recover the ~500 m sedimentary sequence contained in the Lake Chalco basin in the Valley of Mexico. These sediment sequences have the potential to provide an ~800,000 year record of North American climate. This would be a unique climate archive that could develop into the "type sequence" for paleoclimate studies in the Americas. These sediments also contain imprints of the tectonic and volcanic history of the Valley of Mexico.
