Probing the Impact-generated Hydrothermal System in the Chicxulub Crater and Implications for the Early Evolution of Life on Earth

MARUM Seminar
Seminar room 2070
One of the objectives of IODP-ICDP Expedition 364 to the Chicxulub impact crater was to test models of impact-generated hydrothermal systems. Initial results indicate there was a vigorous, long-lived hydrothermal system at the crater. Mineral assemblages track the evolution of the system from sterilizing high temperatures to those suitable for hyperthermophilic and thermophilic organisms. The Chicxulub system is a proxy for impact-generated hydrothermal systems produced during a Hadean epoch of impact bombardment and support an impact-origin of life hypothesis.
