Garriott during a systematic search for meteorites conducted by PSF. Classification and mineralogy (P. Sipiera, Harper; G. Jerman, MSFC; A. Patzer, UAz): has a cumulate texture; metal is interstitial to coarse silicates; olivine, Fa9.2 (range Fa4.8–10.6); augite (Fs4Wo41–46); low Ca-pyroxene (Fs9–11En89–91); plagioclase (An15–18Ab78–82), Fe-Ni metal, troilite, chromite, and apatite; with abundant 120° triple point junctions. shock stage, S1; weathering grade, W1. The meteorite is mineralogically similar to Graves Nunataks (GRA) 98028 but larger grain size (300–400 µm) than GRA 98028 (50–100 µm). Specimens: all at PSF. | ||||||||||||||||||||||
