Description

    The Chicxulub Crater, Yucatan Peninsula in Mexico, is one of the largest impact structures on the Earth. However,  The details of impact processes of the Chicxulub crater is largely unknown.<br>    In this study, we measured and analyzed planar deformation features (PDFs) on shocked quartz grains derived from asteroid impact at the K-Pg boundary deposits both within the Chicxulub crater (Yaxcopoil-1 site) in order to estimate peak shock pressure of ejecta deposited within the Chicxulub crater. We revealed that within and around the crater, from moderately to highly shocked quatrz grains and have been deposited for several days.
