NOx production and rainout from Chicxulub impact ejecta reentry
The Chicxulub impact 66.0 Ma ago initiated the second biggest extinction in the Phanerozoic Eon. The cause of the concurrent oceanic nitrogen isotopic anomaly, however, remains elusive. The Chicxulub
Energy, volatile production, and climatic effects of the Chicxulub Cretaceous/Tertiary impact.
A comprehensive analysis of volatiles in the Chicxulub impact strongly supports the hypothesis that impact-generated sulfate aerosols caused over a decade of global cooling, acid rain, and disruption
Quantifying the Release of Climate‐Active Gases by Large Meteorite Impacts With a Case Study of Chicxulub
Potentially hazardous asteroids and comets have hit Earth throughout its history, with catastrophic consequences in the case of the Chicxulub impact. Here we reexamine one of the mechanisms that
The Chicxulub Asteroid Impact and Mass Extinction at the Cretaceous-Paleogene Boundary
Records of the global stratigraphy across this boundary are synthesized to assess the proposed causes of the Cretaceous-Paleogene boundary and conclude that the Chicxulub impact triggered the mass extinction.
Impact production of C02 by the Cretaceous/Tertiary extinction bolide and the resultant heating of the Earth
EVIDENCE at the Cretaceous/Tertiary boundary suggests that the proposed 'extinction' bolide1 struck a continental or shallow marine terrane. This evidence includes: shocked quartz and feld-spar
Yucatán subsurface stratigraphy: Implications and constraints for the Chicxulub impact
Much of the discussion about the effects of an end-of-Cretaceous impact by a large extraterrestrial body in northwestern Yucatan has been done in the context of limited and partly erroneous published
Revisiting wildfires at the K‐Pg boundary
The discovery of large amounts of soot in clays deposited at the Cretaceous‐Paleogene (K‐Pg) boundary and linked to the ~65 Ma Chicxulub impact crater led to the hypothesis that major wildfires were
