Petrophysics of Chicxulub Impact Crater's Peak Ring

A new set of physical property measurements was undertaken on 29 peak‐ring samples from the IODP‐ICDP Expedition 364. Among the studied lithologies, the dominant one recovered in the peak ring…

Life before impact in the Chicxulub area: unique marine ichnological signatures preserved in crater suevite

To fully assess the resilience and recovery of life in response to the Cretaceous–Paleogene (K-Pg) boundary mass extinction ~ 66 million years ago, it is paramount to understand biodiversity prior to…

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…

The Chicxulub impact and its environmental consequences

The extinction of the dinosaurs and around three-quarters of all living species was almost certainly caused by a large asteroid impact 66 million years ago. Seismic data acquired across the impact…

Resolving impact volatilization and condensation from target rock mixing and hydrothermal overprinting within the chicxulub impact structure

Importance of pre-impact crustal structure for the asymmetry of the Chicxulub impact crater

The final geometry of an impact crater can be significantly influenced by the geological and geomorphological structure of the impact site; therefore, it may not on its own provide accurate…

An extraterrestrial event at the Cretaceous–Tertiary boundary

Closely spaced samples from an uninterrupted calcareous pelagic sequence across the Cretaceous–Tertiary boundary reveal that the extinction of planktonic Foraminifera and nannofossils was abrupt…

Geochemical variability of the Yucatàn basement: Constraints from crystalline clasts in Chicxulub impactites

Abstract— The 65 Ma old Chicxulub impact structure with a diameter of about 180 km is again in the focus of the geosciences because of the recently commenced drilling of the scientific well…

CHICXULUB , ANATOMY OF A LARGE IMPACT STRUCTURE : FROM IMPACTITE TO EJECTA DISTRIBUTION

The impactites from the Cretaceous-Tertiary boundary Chicxulub crater in Yucatan are described. Chicxulub is one of the largest and best-preserved terrestrial craters. It is thus one of the only…

An emplacement mechanism for the mega‐block zone within the Chicxulub crater, (Yucatán, Mexico) based on chemostratigraphy

Abstract– To better constrain the emplacement mechanism of the so‐called “mega‐block zone,” a structurally complex unit of target rocks within the Chicxulub impact structure, the stratigraphic…

An expanded sedimentary section provides an opportunity to elucidate conditions in the nascent Chicxulub crater during the hours to millennia after the Cretaceous‐Paleogene (K‐Pg) boundary impact.…

Evidence for ocean water invasion into the Chicxulub crater at the Cretaceous/Tertiary boundary

Abstract— The possibility of ocean water invasion into the Chicxulub crater following the impact at the Cretaceous/Tertiary boundary was investigated based on examination of an impactite between…
