Writeup from MB 109:

Crescent Valley 001 (CV 001)        40°25.924’N, 116°30.754’W

Nevada, United States

Find: 2013 Oct 16

Classification: Ordinary chondrite (H4)

History: These two fragments (which were less than a meter apart) were recovered by Robert Verish while he was searching for meteorites at the south end of a small drylake.

Physical characteristics: These 1.6 and 0.87 g fragments are physically paired. There are still some small fragments missing. The orange-brown exterior has lost its fusion-crust due to weathering. A cut surface shows a brown interior with visible chondrules and metal-grains.

Petrography: (D. Sheikh, FSU) Sample contains well-defined chondrules (Av. 500 μm) along with metal and troilite. Secondary Fe-oxides present as well.

Geochemistry: Olivine (Fa18.8±0.6, n=14), Low-Ca Pyroxene (Fs16.4±0.7Wo1.1±0.1, n=12).

Classification: Ordinary Chondrite (H4)

Specimens: 0.87 grams at UCLA; main mass with Verish.
