The article offers information on a study that explores globally distributed iridium layer preserved within the Chicxulub impact structure. It mentions the concentration of ultrafine meteoritic matter occurs in the post-impact sediments that cover the crater peak ring. It discusses that iridium layer provides a key temporal horizon precisely linking Chicxulub to K-Pg boundary sections worldwide.
