Abstract

The determination of a nearby supernova (SN) explosion confirmed by the detection of radioisotopes on Earth, was investigated. A well resolved time profile of the ⁶⁰Fe concentration in a deep-sea ferromanganese crust was measured and a highly significant increase was also found. It was observed that the amount of ⁶⁰Fe was compatible with the deposition of ejecta from a SN at a distance of a few 10 pc. The results show that a well defined time of the SN explosion makes it possible to search for plausible correlations with other events in Earth's history.
