Writeup from MB 104:

Superior Valley 032 (SuV 032)        35°14’13.4"N, 117°6’0.4"W

California, USA

Find: 2014 Dec 19

Classification: Ordinary chondrite (H5)

Physical characteristics: The sample consists of two pieces which fit together. The bigger piece is 1.9 × 1.4 cm and weighs 6.89 g. The second piece is 0.7 × 1.5 cm and weighs 2.24 g. When the two pieces are assembled, it is clear that an additional piece is missing. Both pieces have dark-brown fusion crust with rusty patches.

Petrography: The meteorite has a granular texture consisting mainly of recrystallized chondrules integrated with the matrix. Only a few relict chondrules are visible ranging from 0.4-1 mm. Low-Ca pyroxene grains do not exhibit polysynthetic twinning. Plagioclase grain sizes are ~10-20 μm. Metal grains have a ragged texture; some small shock veins are visible. Some metal grains contain small (5-10 μm) irregular grains of troilite; a few ~5-10 μm copper grains occur with the irregular troilite grains.
