A longitudinal slice measuring ~5 x 2.5 cm was examined prior to thin section preparation. The slice exhibits a prominent reheated α2 structure around the entire margin, reaching to a depth of up to 3 mm. The section includes inclusions of troilite, silicates, likely graphite and occasional metal that reach up to 1.5 cm in maximum dimension. The meteorite exhibits a Widmanstätten pattern indicative of formation from a single austenite crystal and with kamacite bandwidths of ~1.5-2 mm. Examination of the polished thin section reveals polyminerallic inclusions of olivine (Fa5), low-Ca pyroxene (Fs6), high-Ca pyroxene (Fs3), plagioclase, metal, troilite, graphite, schreibersite and rare chromite. No fusion crust or heat-altered zone was present. The metallic host contains poorly-defined, short kamacite lamellae that exceed 0.5 mm in width. A microprobe traverse revealed an average composition of 7.8 wt.% Ni, 0.06 wt.% P and 0.57 wt.% Co. The low P value likely reflects the exsolution of schreibersite. The meteorite in an iron, probably of group IAB. |
