The Chicxulub crater is the only wellpreserved peak-ring crater on Earth and linked, famously, to the KT or K-Pg mass extinction event. For the first time, geologists have drilled into the peak ring of that crater in 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 paleobiological consequences are among the most captivating topics being discussed in the geologic community. Here we focus attention on the geological processes that shaped the~ 200-km-wide impact crater responsible for that discussion and the expedition’s first year results.
