Writeup from MB 108:

Star Flat        N39°21.8717’, W118°37.1482’

Nevada, United States

Find: 2013 Oct 18

Classification: Ordinary chondrite (H5)

History: Main mass holder is Robert Verish, who witnessed its recovery by the finder, Monika Waiblinger, in the middle of a dry lake on March 31, 2011.

Physical characteristics: A roughly egg-shaped, dark-brownish black stone with a very weathered exterior that has sparse patches of relict fusion-crust. The interior is uniformly brown. Cut surfaces are sparsely flecked with very small metal-grains, but much troilite and many visible chondrules.

Petrography: (Daniel Sheikh, FSU) Chondrule boundaries blurred (500±100 µm, N=7). Recrystallized coarse-grained matrix with plagioclase (20-50 μm). Interconnected iron-oxide veins.

Geochemistry: Olivine, Fa19.7±0.2 (N=22); orthopyroxene Fs19.4±0.2Wo2.4±0.1 (N=22).

Classification: Ordinary Chondrite (H5)

Specimens: 25.8 g at UCLA; main mass with Verish.
