Soraya Alfred—Impacts aren’t all bad! Impacts, like Chicxulub, can generate porosity, permeability, heat, and fluid flow that creates self-sustaining subsurface ecosystems. #LPSC2025
A photograph of a sketch of Soraya Alfred’s talk at LPSC 2025. The sketch is in my small conference notebook. and there are pens/pencils below it for scale. The sketch is dominated on the left side of the page with a perspective view of the Chicxulub impact crater. On the left side you see the impact happening, with a big ejecta blanket rocketing into the sky. On the right side you see the crater some time later: a complex crater with a peak ring, partially filled by water. Below that sketch is a little sketch of a T rex, “about to have a bad day.” To the right is a cross section of the “after” case for Chicxulub, showing a cross section of the peak ring structure, colored by temperature (yellow = hot, blue = cold). In the downwarped sediment layers, there are streamlines (in green/blue) showing that fluid is brought from the warm depths up to the surface, and back down. This supports ecosystems at depth below the surface.
