The Chicxulub crater drilling program

Continuous core recovery, core scanning and physical property logging for characterization and petrophysics analyses in the Chicxulub drilling projects are reviewed. We focus on the Yaxcopoil-1 borehole, one of the Chicxulub boreholes drilled in the terrace zone that sampled the post-impact carbonat...

We focus on the Yaxcopoil-1 borehole, one of the Chicxulub boreholes drilled in the terrace zone that sampled the post-impact carbonates, impact breccias and target Cretaceous carbonates. Yaxcopoil-1 was continuously cored from 404 m to 1511 m, with core recovery of 98.5 %. The laboratory studies on drill cores include digital core scan images of cores and slabs, physical properties, mineralogy and geochemistry. The crater formed by an asteroid impact on the Yucatan platform at ~66 Ma ago, marking the Cretaceous/Paleogene boundary. It has a 200 km rim diameter and is not exposed at the surface, covered by ~1 km of carbonate sediments; thus its studies require geophysical surveys and drilling. Core analyses and 3-D and 2-D scans provide data on the stratigraphy, composition, textures, deformation and hydrothermal alteration. Impact breccias are heterogeneous materials, with clasts of melt, carbonates and basement in carbonate-rich and melt-rich matrix. The lower breccias were emplaced by high-temperature basal surges, which were followed by collapse of the impact plume and lateral curtains. The upper breccias are reworked air-fall deposits of the post-collapse stage. The crater formed a depositional basin, filled by sediments that preserve records of sea level and sediment transport across the platform. The Paleogene sequence is formed by limestones, dolomites, calcarenites and limestone conglomerates. The target sequence is formed by limestones, calcarenites, dolomite breccias and anhydrites. The studies show the usefulness of continuous coring and core analyses to constraint the crater formation, impact deformation, ejecta and impact dynamics. 22025-01-0120252025-01-01Articlehttp://purl.org/coar/resource_type/c_6501VoRhttp://purl.org/coar/version/c_970fb48d4fbd8a85info:eu-repo/semantics/articleapplication/pdfhttps://ddd.uab.cat/record/308389https://dx.doi.org/urn:doi:10.1344/GeologicaActa2025.23.3reponame:Dipòsit Digital de Documents de la UABinstname:Universitat Autònoma de BarcelonaInglésengopen accesshttp://purl.org/coar/access_right/c_abf2Aquest document està subjecte a una llicència d'ús Creative Commons.

description Continuous core recovery, core scanning and physical property logging for characterization and petrophysics analyses in the Chicxulub drilling projects are reviewed. We focus on the Yaxcopoil-1 borehole, one of the Chicxulub boreholes drilled in the terrace zone that sampled the post-impact carbonates, impact breccias and target Cretaceous carbonates. Yaxcopoil-1 was continuously cored from 404 m to 1511 m, with core recovery of 98.5 %. The laboratory studies on drill cores include digital core scan images of cores and slabs, physical properties, mineralogy and geochemistry. The crater formed by an asteroid impact on the Yucatan platform at ~66 Ma ago, marking the Cretaceous/Paleogene boundary. It has a 200 km rim diameter and is not exposed at the surface, covered by ~1 km of carbonate sediments; thus its studies require geophysical surveys and drilling. Core analyses and 3-D and 2-D scans provide data on the stratigraphy, composition, textures, deformation and hydrothermal alteration. Impact breccias are heterogeneous materials, with clasts of melt, carbonates and basement in carbonate-rich and melt-rich matrix. The lower breccias were emplaced by high-temperature basal surges, which were followed by collapse of the impact plume and lateral curtains. The upper breccias are reworked air-fall deposits of the post-collapse stage.

The Paleogene sequence is formed by limestones, dolomites, calcarenites and limestone conglomerates. The target sequence is formed by limestones, calcarenites, dolomite breccias and anhydrites. The studies show the usefulness of continuous coring and core analyses to constraint the crater formation, impact deformation, ejecta and impact dynamics.
