The longitudinal section measures ~7 x 7 mm. One end of the section is rounded and represents the original surface of the meteorite. The opposite end is truncated along a linear edge. The bulk of the meteorite is composed of kamacite with an α2 structure. The section is bounded by a weathered crust that rarely overlies small pockets of fusion crust. Inset from the straight edge of the section and parallel to it at regular spacings of ~2 mm are, first, a taenite lamellae (up to 34 wt.% Ni) ~50 µm in width which contain along its length irregular ~100 µm pockets of taenite and P-rich, Ni-rich melt (28 wt.% Ni, 11 wt.% P) in a eutectic relationship. A further ~2 mm into the meteorite is a fracture, now filled with terrestrial iron hydroxides, that includes larger grains of taenite (up to 23 wt.% Ni). The larger particles, reaching a few hundreds microns, sometimes contain oriented kamacite plates. A representative traverse yields an average composition of 7.2 wt.% Ni, 0.1 wt.% P and 0.6 wt.% Co. The meteorite is an iron and could be related to a number of groups (e.g., IIAB, IIIAB, IAB). The Ni and P concentrations might suggest group IIIAB. It is, however, unlikely that it is representative of the larger mass from which it was derived. |
