Lucerne Valley 028           34°29′25′′N, 116°57′34′′W

San Bernardino County, California, USA

Find: 11 October 2003

Carbonaceous chondrite (CK4)

History: Two small dark gray stones weighing 3.0 g (LV 028) and 10.1 g (LV 029) were found within 100 meters of each other by R. Matson while searching for meteorites on Lucerne Dry Lake. Six additional fragments (LV 030, 031, 032, 035, 036, and 037) were found during detailed searches in March 2004, scattered over a linear kilometer. Total mass is 36.61 g.

Petrography: (A. E. Rubin, UCLA) The meteorites contain ~15 vol% chondrules with a mean apparent diameter of ~500 µm. Chondrule types include BO, PO, and POP. The principal opaque phases are magnetite and pyrrhotite. The magnetite occurs both as small grains and as clumps as large as 250 µm. The pyrrhotite is moderately abundant. Olivine (Fa33.2±0.4), groundmass of 25–50 µm.

Classification: The stones are carbonaceous (CK4); moderate shock.

Specimens: A 7.33 g type specimen is on deposit at UCLA. RMatson holds the main mass.
