Crescent Valley 002 (CV 002)        40°25.754’N, 116°30.729’W

Nevada, United States

Find: 2013 Oct 22

History: This nearly whole individual was recovered 315 m SSE of Crescent Valley 001 by Robert Verish while he was searching for meteorites at the south end of a small drylake.

Physical characteristics: This 6.4 g orangish-brown, rectangular, nearly whole stone has a rough exterior, which has had its fusion cust weathered-away. A cut surface reveals visible chondrules, metal-grains and many fractures filled-in with weathering-products.

Petrography: (D. Sheikh, FSU) Sample contains well-defined chondrules (Av. 500 μm). Sample is heavily weathered and contains numerous interconnected Fe-oxide veins; metal and troilite absent.

Geochemistry: Olivine (Fa18.6±0.5, n=12), Low-Ca Pyroxene (Fs16.9±0.8Wo1.1±0.2, n=13).
