The Chicxulub crater, famously linked to the dinosaur extinction event, is the only well preserved peak-ring crater on Earth. For the first time, geologists have drilled into the peak ring of that crater during the International Ocean Discovery Program and International Continental Scientific Drilling Program (IODP-ICDP) Expedition 364.

The Chicxulub impact event, the environmental calamity it produced, and the biological consequences are among the most captivating topics being discussed in the geologic community.

SSERVI’s David Kring, PI of the LPI-USRA team in Houston, TX, wrote a feature article in the October 2017 issue of GSA Today that compares and contrasts the NEA Chicxulub impact crater (on Earth) with the Schrodinger Basin (on the Moon). The paper was given the cover of GSA Today, and the article will be featured at the October GSA meeting.

Read more about the geological processes that shaped the ~200-km-wide impact crater and the expedition’s first year results.
