Emplacement of cretaceous-tertiary boundary shocked quartz from chicxulub crater.
Observations on shocked quartz in Cretaceous-Tertiary (K-T) boundary sediments compellingly tied to Chicxulub crater raise three problems. First, in North America shocked quartz occurs above the main K-T ejecta layer. Second, shocked quartz is more abundant west than east of Chicxulub. Third, shocked quartz reached distances requiring initial velocities up to 8 kilometers per second, correspond...
متن کاملThree Dimensional Gravity Field Modelling of the Chicxulub Impact Crater. A
Introduction: The structure of the Chicxulub crater has been actively investigated by potential field modeling, seismic reflection and refraction surveys, and drilling during the decade since its recognition as the crater responsible for mass extinction which terminated the Cretaceous Period. Given the data sets that are now available to delineate crater structure a surprisingly diverse number ...
متن کاملInfluence of Target Yield Stress on Crater Dimensions: a Numerical Approach Based on Chicxulub
Introduction: AUTODYN [1] is used to consider the effect of altering the yield stress of geological materials on the resultant crater dimensions. This investigation is part of a series of fundamental inquiries into the sensitivities of AUTODYN, in order to fully validate the code as an appropriate tool to study large planetary impact crater formation. The majority of current AUTODYN application...
متن کاملCaldera rim collapse: A hidden volcanic hazard
Following the emblematic fl ank collapse of Mount St Helens in 1981, numerous models of flank sliding have been proposed. These models have allowed to largely improve the understanding of mechanisms involved in such landslides, which represent a tremendous risk for populations living around volcanoes. In this article, a new mode of landslide formation, related to buried calderas, is described. ...
متن کاملThe hidden teeth of sloths: evolutionary vestiges and the development of a simplified dentition
Xenarthrans are unique among mammals in retaining simplified teeth that are rootless and homodont, which makes it difficult to determine dental homologies. We apply computerized tomography to prenatal developmental series of extant sloths, Bradypus and Choloepus, to further elucidate the patterns of morphological variation in their dentition. We also propose new criteria based on sequences of d...
