Chicxulub Crater: A possible Cretaceous/Tertiary boundary impact crater on the Yucatán Peninsula, Mexico
We suggest that a buried 180-km-diameter circular structure on the Yucatan Peninsula, Mexico, is an impact crater. Its size and shape are revealed by magnetic and gravity-field anomalies, as well as…

Support for the lunar cataclysm hypothesis from lunar meteorite impact melt ages.
TLDR
The lack of impact melt older than 3.92 Ga supports the concept of a short, intense period of bombardment in the Earth-moon system at approximately 3.9 Ga.

Cataclysmic bombardment throughout the inner solar system 3.9–4.0 Ga
[1] Cohen et al. [2000] recently confirmed the hypothesis that the Moon was resurfaced by an intense period of impact cratering ∼3.9 Ga ago and, by inference, that the Earth also sustained…

The Chicxulub Asteroid Impact and Mass Extinction at the Cretaceous-Paleogene Boundary
TLDR
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.

The Origin of Planetary Impactors in the Inner Solar System
TLDR
Old craters from a unique period of heavy bombardment that ended ∼3.8 billion years ago were made by asteroids that were dynamically ejected from the main asteroid belt, possibly due to the orbital migration of the giant planets.

Widespread mixing and burial of Earth’s Hadean crust by asteroid impacts
TLDR
It is found that the surface of the Hadean Earth was widely reprocessed by impacts through mixing and burial by impact-generated melt, which may explain the age distribution of Hadesan zircons and the absence of early terrestrial rocks.

Hydrocode simulation of the Chicxulub impact event and the production of climatically active gases
We constructed a numerical model of the Chicxulub impact event using the Chart-D Squared (CSQ) code coupled with the ANalytic Equation Of State (ANEOS) package. In the simulations we utilized a…
