Hi Matteo. Yes, it appears to be stable. Comparing this to nantan is somewhat like comparing apples to oranges. Nantan has a nickel content of only 6.88% and is a member of the IAB main group. This silicated iron has a nickel content of 13.8% and appears to be a member of the IAB LM subgroup which corresponds to the old IIIC group. It is noteworthy that its Cu and Sb concentrations are higher than those in any current member of this IAB subgroup. Also, irons which are found in moist environments tend to be less stable than irons found in dry environments. Somone may correct me, but I believe Nantan is from a relatively moist environment while NWA 2680 is a desert iron.
The elmental composition of NWA 2680 is: : Cr 96 µg/g, Co 5.4 mg/g, Ni 138 mg/g, Cu 560 µg/g, Ga 26 µg/g, As 21 µg/g, Sb 890 ng/g, W 0.33 µg/g, Ir 2.1 µg/g, Au 1.77µg/g.
