Peak rings are a feature of large impact craters on the terrestrial planets and are generally believed to be formed from deeply buried rocks that are uplifted during crater formation. The precise lithology and kinematics of peak ring formation, however, remains unclear. Previous work has revealed a suite of bright inward dipping reflectors beneath the peak ring at the Chicxulub impact crater and that the peak ring was formed from rocks with a relatively low seismic velocity. New two-dimensional… 

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


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).

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.

Geophysical characterization of the Chicxulub impact structure

[1] 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

Imaging the Chicxulub Central Crater Zone from Large-Scale Seismic Acoustic Wave Propagation and Gravity Modeling

Large impact structures are characterized by peak ring and central uplifts with lateral/vertical mass transport during late formation stages. Here we investigate the Chicxulub crater, which has been

Tracing shock-wave propagation in the Chicxulub crater: Implications for the formation of peak rings

The Chicxulub crater (Yucatán Peninsula, Mexico) is considered exceptional in many scientific aspects; morphologically it is the only known impact structure on Earth with a well-preserved peak

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.

Vertical Seismic Profiling of the Chicxulub Impact Basin Peak Ring

Here we detail the vertical seismic profile (VSP) collected during Expedition # 364 of the International Ocean Discovery Project / International Continental Scientific Drilling Program (IODP/ICDP).



Seismic images of Chicxulub impact melt sheet and comparison with the Sudbury structure

Chicxulub is the only known impact structure on Earth with a fully preserved peak ring, and it forms an important natural laboratory for the study of large impact structures and understanding of

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

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

Upper crustal structure of the Chicxulub impact crater from wide-angle ocean bottom seismograph data

We used travel times recorded by 23 ocean bottom seismograph (OBS) receivers to model crustal structure of the Chicxulub impact crater. The OBSs were located along Chicx-A/A1, a deep reflection

Chicxulub central crater structure: Initial results from physical property measurements and combined velocity and gravity modeling

Abstract The Chicxulub crater in Mexico is a nearly pristine example of a large impact crater. Its slow burial has left the central impact basin intact, within which there is an apparently uneroded

Gravity and magnetic field modeling and structure of the Chicxulub Crater, Mexico

The Chicxulub crater is an ∼180-km-diameter peak-ring crater based on drill hole logs and samples, potential fields, seismic reflection profiles, and surface fracture patterns. A structural cross

Hydrocode simulations of Chicxulub crater collapse and peak-ring formation

We use hydrocode modeling to investigate dynamic models for the collapse of the Chicxulub impact crater. Our aim is to integrate the results from numerical simulations with kinematic models derived

Is Ries crater typical for its size? An analysis based upon old and new geophysical data and numerical modeling

Considering the Ries crater as an example for middle-sized complex impact structures on Earth, we use geophysical data to examine the structure underneath the crater and simulate the formation
