Writeup from MB 109:

Black Butte 002 (BB 002)        41°24.207’N, 118°13.478’W

Nevada, United States

Find: 2015 Aug 9

Classification: Ordinary chondrite (H3-4)

History: While searching for meteorites, Robert Verish recovered this stone along the apron of a hummock which formed a west-facing stranding-surface.

Physical characteristics: This 9.9 g well-rounded, orangish-brown whole-stone has a rough, fusion-crusted exterior, and a cut surface reveals visible chondrules, metal-grains and troilite in a light-brown groundmass.

Petrography: (D. Sheikh, FSU) Sample contains well-defined chondrules (Av. 600 μm) along with metal and troilite. Both unequilibrated and equilibrated clasts present.

Geochemistry: Olivine in type 3 clasts (Fa17.4-26.1, n=10), Low-Ca Pyroxene in type 3 clasts (Fs15.4-25.6Wo1.0-1.8, n=8), Olivine in type 4 clasts (Fa19.1±0.9, n=12), Low-Ca Pyroxene in type 4 clasts (Fs16.8±0.8Wo1.4±0.3, n=10).

Classification: Ordinary Chondrite (H3-4). The sample contains both unequilibrated (type 3) and equilibrated (type 4) clasts.

Specimens: 2.2 grams at UCLA; main mass with Verish.
