The Fe-Isotope System and Its Applicability as a BiosignatureHigh precision (0.05) Fe isotope analyses show that igneous rocks and loess are invariant but chemical sediments have variable compositions. The relative roles of abiologic and biologic fractionations that produced this range are discussed. Additional information is contained in the original extended abstract.
