ABSTRACT: Evidence gathered to date from topographic data, geophysical data, well logs, and drill‐core samples indicates that the buried Chicxulub basin, the source crater for the ∼65 Ma Cretaceous‐Tertiary (K/T) boundary deposits, is ∼300 km in diameter. A prominent topographic ridge and a ring of gravity anomalies mark the position of the basin rim at ∼150 km from the center. Wells in this region recovered thick sequences of impact‐generated breccias at 200–300 m below present sea level…

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…
