Hydrothermal Alteration of the Impactites at the Icdp Drill Site Yax-1
نویسندگان
چکیده
Introduction. About 100 m of impactites (suevitetype breccias) have been drilled at the ICDP drill site Yax-1 within the Chicxulub impact structure (see [1] for more information). Post-impact hydrothermal alteration including alkali metasomatism and devitrification of impact melt glass has significantly modified the mineralogy and chemistry of the impact breccia lithologies. Hydrothermal alteration has also affected the breccia dikes [2] in the cretaceous megablock and locally the host sediments.

Deformation 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...

Introduction: The nature of the Chicxulub impactor is still not fully understood. Attempts to identify the traces of the impactor from chemical analyses of impactites within the crater are extremely controversial. Ir analyses of samples from the Chicxulub-1 and Yucatan-6 drill cores lead to different results. Nuggets of platinum group elements (PGE) and Ir concentration of more than 1000pg/g we...
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 کاملStable 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 کاملClastic Polymict Dikes in the “megablock” Sequence of the Icdp-chicxulub Drill Core Yax-1
Introduction: The Yaxcopoil borehole (Yax-1) penetrates below the suevitic units through 600 m of sediments (894.9 m – 1510.9 m). These rocks are most likely of Cretaceous age and are regarded as a displaced “megablock”. The stratified sequence was intruded by suevitic dikes (910 m, 916 m), one impact melt dike (1347 m) and several clastic, polymict dikes. The latter are the focus of this study...
