Geophysical data indicate that the 65.5 million years ago Chicxulub impact structure is a multi‐ring basin, with three sets of semicontinuous, arcuate ring faults and a topographic peak ring (PR). Slump blocks define a terrace zone, which steps down from the inner rim into the annular trough. Fault blocks underlie the PR, which exhibits variable relief, due to target asymmetries. The central structural uplift is >10 km, and the Moho is displaced by 1–2 km. The working hypothesis for the… 

Seismic attribute analysis of Chicxulub impact crater

Chicxulub crater formed ~ 66 Ma ago by an asteroid impact on the Yucatan platform in the southern Gulf of Mexico. The crater has a ~ 200 km rim diameter and has been covered by carbonate sediments up

The formation of peak rings in large impact craters

Rock samples from IODP/ICDP Expedition 364 support the dynamic collapse model for the formation of the Chicxulub crater and have implications for far-ranging subjects, from how giant impacts alter the climate on Earth to the morphology of crater-dominated planetary surfaces.

The first day of the Cenozoic

High-resolution section from the Chicxulub peak ring provides insight into the impact environmental effects, including charcoal as evidence for impact-induced wildfires and a paucity of sulfur-rich evaporites from the target supporting rapid global cooling and darkness as extinction mechanisms.

Geophysical signature of the Tunnunik impact structure, Northwest Territories, Canada

In 2011, the discovery of shatter cones confirmed the 28 km diameter Tunnunik complex impact structure, Northwest Territories, Canada. This study presents the first results of ground‐based

Mapping the Chicxulub Impact Stratigraphy and Peak Ring Using Drilling and Seismic Data

We integrate high‐resolution full‐waveform velocity models with seismic reflection images to map the peak ring and impactite stratigraphy at the Chicxulub structure. International Ocean Discovery

Probing the hydrothermal system of the Chicxulub impact crater

The recovered core shows the Chicxulub crater hosted a spatially extensive hydrothermal system that chemically and mineralogically modified ~1.4 × 105 km3 of Earth’s crust, a volume more than nine times that of the Yellowstone Caldera system.

Chicxulub Crater Joint Gravity and Magnetic Anomaly Analysis: Structure, Asymmetries, Impact Trajectory and Target Structures

Modeling gravity and magnetic anomalies over the Chicxulub crater are used to constrain the structure, stratigraphy, and asymmetries. Chicxulub is a multiring ~ 200 km rim diameter structure with a

Seismic imaging and attribute analysis of Chicxulub Crater central sector, Yucatán Platform, Gulf of Mexico

Chicxulub Crater, formed ~66Ma ago by an asteroid impact on the southern Gulf of Mexico, is the best preserved of the three large multi-ring basins in the terrestrial record. The crater structure is



Ringed structural zones with deep roots formed by the Chicxulub impact

The Chicxulub meteorite/comet impact of 65 Ma occurred on the present northeast coast of the Yucatan peninsula of Mexico and is considered by many to have caused a mass extinction at the end of the

Chicxulub: The third dimension of a multi-ring impact basin

The buried 65 Ma Chicxulub impact structure in Mexico is the largest well-preserved impact crater known on Earth. Seismic reflection data have revealed Chicxulub to be a multi-ring basin—it has the

Structural uplift beneath the Chicxulub impact structure

Models of the central structure of large impact craters are poorly constrained, partly because of the lack of well-preserved terrestrial examples, and partly because of the extreme nature of impact

Yucatán karst features and the size of Chicxulub crater

SUMMARY The buried Chicxulub impact structure is marked by a dramatic ring of sinkholes (called cenotes if containing water), and adjacent less prominent partial rings, which have been shown to

Deep crustal structure of the Chicxulub impact crater

We present the results of a wide-angle seismic survey conducted over the Chicxulub impact crater. Profile Chicx-A/A1 is a chord across the offshore portion of the crater, and Chicx-B/F is an

Surface expression of the Chicxulub crater

Analyses of geomorphic, soil, and topographic data from the northern Yucatan Peninsula, Mexico, confirm that the buried Chicxulub impact crater has a distinct surface expression and that carbonate

Mapping Chicxulub crater structure with gravity and seismic reflection data

Abstract Aside from its significance in establishing the impact-mass extinction paradigm, the Chicxulub crater will probably come to exemplify the structure of large complex craters. Much of
