Samenvatting

Introduction: The ~66.0 Myr old, ~200 km diameter Chicxulub impact structure marks the K/Pg boundary and is the only terrestrial crater with an unequivocal peak-ring. In 2016, the International Ocean Discovery Program (IODP) and the International Continental Scientific Drilling Program (ICDP) jointly drilled the 1335 m deep Site M0077A into the Chicxulub peak ring offshore the Yucatán Peninsula and successfully recovered a continuous core from 505.7 to 1334.7 mbsf (meters below sea floor). The core is mainly composed of three lithological units: ~110 m of Paleogene sedimentary rocks (post-impact interval), ~130 m of suevite and impact melt rock (upper peak-ring interval), and ~610 m of granitoid basement, intruded by pre-impact dikes and intercalated with suevites and impact melt rocks [1].
This abstract focuses on Core 40R-Section 1 (616.24‒617.68 mbsf), which samples the ~75 cm “transitional unit” between the upper impactites and early Paleogene sediment. This unique interval of the core, marked by siderophile element enrichments and pyrite-rich intervals, is studied here in detail to better constrain the final phases of impact crater formation and determine the fate of the Chicxulub impactor.
