The maximum of the anomaly between 10.89 and 11.00 m below seafloor correlates with the maximum abundance of microtektites. Iridium abundances, which show the most significant anomaly, reach 0.16 ppb, which is evidence for an extraterrestrial component.Supplement to: Koeberl, Christian (1993): Extraterrestrial component associated with Australasian microtektites in a core from ODP Site 758B.
