As at least a partial validation of modeling of long-destroyed crust in that study, new data from the Chicxulub crater indicate that widespread hydrothermal circulation throughout the shattered rock persisted for at least 8 million years after the Cretaceous-ending impact.

Radioisotopic age constraints and numerical simulations on the duration of hydrothermal activity associated with the Chicxulub impact structure indicate the system was active for 8 million years, four...
