Geophysics: Deep down at Chicxulub
@article{Melosh2001GeophysicsDD, title={Geophysics: Deep down at Chicxulub}, author={Jay Melosh}, journal={Nature}, year={2001}, volume={414}, pages={861-862} }
The best-preserved large impact crater on Earth is overlain by a kilometre of sediment. It is possible to look not only through that wrapping but also beyond, at the effects of the impact at the crust–mantle boundary.

Bedout: A Possible End-Permian Impact Crater Offshore of Northwestern Australia
- GeologyScience
- 2004
The Bedout High, located on the northwestern continental margin of Australia, has emerged as a prime candidate for an end-Permian impact structure and the identification of melt rocks and impact breccias from drill cores located on top of Bedout are consistent with the presence of a buried impact crater.
The ejecta blanket of the Chicxulub impact crater, Yucatán, Mexico
- Geology

Vredefort, Sudbury, and Chicxulub are the largest known terrestrial impact structures. All have been cited as multi-ring basins. The available data indicate that all have some form of multiple-ring…
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…
