The origin of this pattern remains debated, limiting how these isotopic signatures can be used to trace the precursors of terrestrial planets. Here we test the hypothesis that interstellar ices carried supernova-produced nuclides by searching for a supernova nucleosynthetic fingerprint in aqueous alteration minerals from carbonaceous and non-carbonaceous chondrite meteorites. We focus on zirconium, a refractory element that includes the neutron-rich isotope 96Zr formed in core-collapse supernovae. Leaching experiments reveal extreme 96Zr enrichments in alteration minerals, showing that they incorporated supernova material hosted in interstellar ices. We show that the Solar System\u2019s zirconium isotope variability reflects mixing between these ices and an ice-free rocky component. Finally, the presence of supernova nuclides in a volatile carrier supports models where the Solar System\u2019s nucleosynthetic variability was imparted by thermal processing of material in the protoplanetary disk and during planetary accretion.&#8221;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Martin Bizzarro, Martin Schiller, Jesper Holst, Laura Bouvier, Miroslav Groen, Fr\u00e9d\u00e9ric Moynier, Elishevah M.
