متن کاملGeochemistry of carbonaceous impactites from the Gardnos impact structure, Norway
The Gardnos impact structure in southern Norway is one of only two known impact structures (among 175) whose impactites contain significant amounts (typically 0.2–1.0 wt.%) of carbon, or 5 to 10 times the amount present in the target rocks; Sudbury, Canada is the other. This study extends a previous investigation of the geochemistry and petrology of Gardnos impactites (French et al., 1997) with...
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 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...
