Stable Isotope Record of Post-impact Fluid Activity in the Chicxulub Crater as Exposed by the Yaxcopoil-1 Borehole
Introduction: Cavities of secondary calcite and veins of secondary anhydrite and quartz in the Yuca-tan-6 borehole drilled into the Chicxulub structure suggested the impact generated a hydrothermal system [1, 2]. Based on work at other craters, mostly Siljan and Puchezh-Katunki [3, 4], we estimate this system could be several kilometers deep in the center of the crater and may extend to the rim...
متن کاملPreliminary Results on the Post-impact Hydrothermal Alteration in the Yaxcopoil-1 Hole, Chicxulub Impact Structure, Mexico
Introduction: The results presented here are part of an investigation into the evolution of hydrothermal events associated with the Chicxulub impactites in Yu-catan, Mexico. The study focuses on alteration products in core samples recovered from the Yaxcopoil-1 drill hole, which is located some 60 kilometers from the center of the impact structure. This research contributes to the growing knowl...
متن کاملInitial Assessment of the Excavation and Deposition of Impact Lithologies Exposed by the Chicxulub Scientific Drilling Project, Yaxcopoil, Mexico
Introduction: The Chicxulub Scientific Drilling Project (www.icdp-online.de) recovered a continuous core from a depth of 404 m (in Tertiary cover) to 1511 m (in a megablock of Cretaceous target sediments), penetrating ~100 m of melt-bearing impactites between 794 and 895 m. The Yaxcopoil-1 (YAX-1) borehole is ~60-65 km from the center of the Chicxulub structure, which is ~15 km beyond the limit...
متن کاملDeformation Features of the Cretaceous Units of the Icdp-chicxulub Drill
Introduction: The Yaxcopoil-1 (Yax-1) borehole, 60 km SSW of the center of the Chicxulub crater, penetrated through 600 m of sediments below the impactites (from about 894.9 m to the lowermost drilling depth of 1510.9 m). These rocks which are most likely of Cretaceous age are deformed to various degree and consist of distinct lithologies, predominantly carbonates and sulfates (dolomite, limest...
متن کاملOsmium Isotope Constraints on the Proportion of Bolide Component in Chicxulub
Introduction: There have been numerous previous attempts to identify the projectile that produced the Chicxulub impact crater. Kyte [1] reported a fragment of rock in K/T boundary sediments that had been deposited in the Pacific Ocean. The textures and chemistry of the fragment suggested it was an altered fragment of carbonaceous chondrite material. Kyte interpreted it to be from the Chicxulub ...
