“…Cohenite in iron meteorites is depleted in 13 C by 11.5-12.5‰ relative to coexisting graphite (33)(34)(35). Carbon dissolved in taenite (Fe−Ni alloy) from several types of meteorites is also depleted in 13 C relative to graphite (34,36).…”

“…This is consistent with an earlier report (Bashir et al, 1996). Deines and Wickman (1975) reported C concentrations of 0.5 wt% in taenite in iron meteorites. But according to the phase diagram of Romig and Goldstein (1 978), this is too high for C in solid-solution in taenite at low temperatures.…”

“…It is an issue of kinetics whether cohenite or graphite appears as a C-bearing condensed solid phase. Cohenite is often observed among iron meteorites enriched in C (Deines andWickman, 1973, 1975) and sometime among unequilibrated ordinary chondrites, although often nonstoichiometric (e.g. Hutchison et al, 1987).…”
