From: Allabogdanite, the high-pressure polymorph of (Fe,Ni)2P, a stishovite-grade indicator of impact processes in the Fe–Ni–P system

Figure 2

The crystal of allabogdanite residing in the center of the envelope-like kamacite crystal. Kamacite, in due course, is hosted by the taenite single crystal. The thin tetrataenite rim and so-called ≪cloudy zone≫ are visible at the interface between taenite and kamacite. The Barbianello meteorite. (a) Photo in reflected light. (b) Image of backscattered electrons (BSE). The bottom row shows elemental maps for nickel, iron, phosphorus and oxygen, respectively. Legend (Fig. 2) (b): Abg, allabogdanite; α, kamacite [body-centered cubic α-(Fe,Ni)]; γ, taenite [face-centered cubic γ-(Fe,Ni)]; L10, tetrataenite (ordered FeNi); Ox, supergene Fe-Ni oxides.
