Abstract
IODINE–XENON dating has established that iron sulphide in the Orgueil carbonaceous meteorite is one of the oldest known meteoritic mineral phases, and probably dates from the condensation stage of the early Solar System1. This sulphide, although generally assumed to be troilite, FeS, is in fact the Fe-deficient monosulphide, pyrrhotite, (Fe,Ni)9S10, containing ∼ 1 weight % Ni (ref. 2). The purpose of this note is to suggest that such mineral chemistry is inconsistent with equilibrium condensation, and that the course of condensation may have been modified by kinetic effects.
