Rocks exposed along Darting Minnow Creek

Caption

Closeup of the rocks exposed along Darting Minnow Creek. The round, white ejecta “spherules” condensed out of ejecta plume from the vaporized Chicxulub rocks and rained down on the Earth in the period after the impact. The ejecta materials at Darting Minnow Creek contain the sulfur that was derived from the Chicxulub crater and the sulfur isotope anomalies that confirm the formation of abundant stratospheric sulfur aerosols that caused extended cooling after the impact.
