Advanced aqueous alteration in primitive meteorites: Micro‐ to nanoscale studies of CR1 iron sulfides

Meteoritics &Planetary Science, Volume 61, Issue 8, Page 1806-1825, August 2026.
Abstract This study documents micro‐ to nanoscale observations of primary nebular and secondary parent body iron sulfides in the CR1 GRO 95577. Despite the extensive alteration of the bulk sample, some primary sulfides managed to avoid alteration, having originally formed in the solar nebula during chondrule formation by either fission‐sulfidization or
