Abstract Live 60 Fe has recently been reported in a deep-ocean ferromanganese crust. Analysis of the isotopic ratios in the sample suggests that the measured 60 Fe abundance exceeds the levels generated by terrestrial and cosmogenic sources, and it has been proposed that the excess of 60 Fe is a signature of a supernova that exploded near the earth several Myr ago. In this paper, we consider the possible background sources, and confirm that the measured 60 Fe is significantly higher than all… CONTINUE READING
