DESCRIPTION:The Chicxulub impact crater is widely renowned for its associa
 tion with the extinction of the non-avian dinosaurs at the end of Cretaceo
 us period (66 Ma ago). It is the best-preserved large impact structure on 
 Earth and the only crater with an unequivocal\, topographic peak ring. In 
 2016\, IODP-ICDP expedition 364 drilled into the peak ring of the Chicxulu
 b impact structure\, recovering impactite lithologies of the peak ring and
  a succession of Palaeogene sedimentary rocks. Here\, I will summarise pre
 liminary results from the expedition\, including sedimentalogical\, geoche
 mical\, and structural observations. In particular\, I will discuss new in
 sights into the process of peak ring formation.
