Superior Valley 014                          35°14′160′′N, 117°02′527′′W

San Bernardino County, CA, USA

Find: 25 August 2002

Achondrite (acapulcoite)

History: A 1.77 g specimen was found by Jason Utas.

Petrography: (A. Rubin, UCLA) The rock has a granular texture consisting mainly of quasi-equant olivine and low-Ca pyroxene grains from 60 to 500 µm in size and averaging ~160 µm. Accessory plagioclase grains ~200 µm with polysynthetic twinning are also present. In some areas the silicate grains are densely packed and many grain boundaries meet at 120° triple junctions. In other areas the silicate grains are separated and surrounded by limonite. The separated silicate grains range in shape from fragmental to subrounded to subhedral. No relict chondrules were observed. Some silicate grains contain 100–300 µm long curvilinear trails of 2–4 µm chromite blebs. The rock is very weathered and contains abundant limonite and patches of clay phases. Nevertheless, a few patches of troilite and rare grains of metallic Fe,Ni are present.

Geochemistry: Olivine (Fa4.6), pyroxene (Fs6.9±0.1Wo2.9±1.6).

Classification: Achondrite (acapulcoite); moderate shock. Specimens: A 0.49 g type specimen is on deposit at UCLA. The main mass is held by Jason Utas.
