We investigated the phosphorus (P) and iron (Fe) fractionation in four cores with anoxic sediments, deposited during the mid-Cretaceous oceanic anoxic event 2 (~94 Ma) and the Paleocene-Eocene thermal maximum (?55 Ma), that were exposed to oxygen after core recovery. Surprisingly, P associated with...
