Abstract

The discovery of live

⁶⁰Fe in a deep-sea crust with proposed interstellar origin followed by evidence for elevated interplanetary

³He in the same crust raised the question on how to unambiguously identify the true production site of the identified

⁶⁰Fe. Here, we show the implementation of the dyadic radionuclide system

⁶⁰Fe/

⁵³Mn to serve as a tool for the identification of surplus interstellar

⁶⁰Fe over interplanetary production. The recent updates in experimental

⁶⁰Fe and

⁵³Mn data from iron meteorites as well as in production rate models confirm the validity and robustness of this dyadic system for future applications.
