Chicxulub: Drilling the K-Pg Impact Crater
Chicxulub multiring impact basin
(No data returned by database query)
The Chicxulub impact crater, Mexico, is unique. It is: 1) the only known terrestrial impact structure that has been directly linked to a mass extinction event, 2) the only one of the three largest impact structures on Earth that is well-preserved, 3) the only terrestrial crater with a global ejecta layer, and 4) the only known terrestrial impact structure with an unequivocal topographic “peak ring”. Chicxulub’s role in the K-Pg mass extinction and its exceptional state of preservation make it an important natural laboratory for the study of both large impact crater formation on Earth and other planets, and the effects of large impacts on the Earth’s environment and ecology.
