Abstract

Presence of 60 Fe in early Solar System was established more than two decades ago, but the Solar System initial ratio of 60 Fe/ 56 Fe is, still, not well constrained.Isotopic studies of bulk meteorites samples from differentiated meteorites, achondrites, and chondrules suggest a low Solar System initial 60 Fe/ 56 Fe value of ~2×10 -8 , while the in-situ studies using secondary ion mass spectrometer suggest a much higher Solar System initial value of ~7×10 -7 .
