NWA 032, Rare Early Lunar Meteorite, Micromount

$15.00

NWA 032 was recovered out of the Saharan Desert of Morocco in October of 1999. It was purchased by a group of European collectors and analyzed by Dr. Ted Bunch at Northern Arizona University. It was classified as a basaltic lunar breccia. The meteorite was a single stone that weighed a modest 300 grams prior to cutting and classification. The remainder was quickly absorbed into collections and it is rarely seen on the collector market now.

The specimen being offered here is a "Bessey Speck" micromount - it is a single solid fragment that weighs approx 1-2mg. 

Refer to the photo. The black centimeter cube is shown for scale and is not included. You are purchasing the specimen shown. Your purchase will include a labeled gemjar for safe storage.

Found 1999 October

Lunar meteorite (olivine-pyroxene basalt)

A stone of ~ 300 g was found in the desert (see Table 9). Classification and mineralogy (T. Fagan, UHaw; T. Bunch and J. Wittke, NAU): olivine, pyroxene, and chromite phenocrysts occur in a groundmass of elongate, zoned pyroxene (En1–25Wo15–25) and feldspar ( ~ An85) crystals radiating from common nucleation sites; opaque phases include elongate, skeletal ilmenite, troilite, and trace metal; olivine phenocrysts ( ~ 12 vol%) up to 300 μm are zoned from Fo65 (cores) to Fo60 (rims) and commonly have chromite inclusions; pyroxene phenocrysts ( ~ 5 vol%) are complexly zoned, with En4 0–50 Wo20–40 and En15–25Wo10–20 domains; both olivine and pyroxene phenocrysts surrounded by Fe-rich quenched margins (olivines, ~ Fo30; pyroxenes, En5–25Wo15–30); glass with ~ 45.7 wt% SiO2 occurs in semicontinuous shock veins up to 50 μm wide; some terrestrial weathering products are present in fractures, but primary assemblage is essentially unaltered.  Oxygen-isotopic compositions (R. Clayton, UChi): δ18O = +5.63‰, δ17O = +2.92‰.  Bulk composition (in wt%, E. Jarosewich, SI):  SiO2 = 44.7; TiO2 = 3.08; Al2O3 = 8.74; FeO = 23.0; MnO = 0.33; MgO = 8.45; CaO = 10.9; Na2O = 0.37; K2O = 0.11; H2O = 0.06.  Specimens:  type specimen, about 5–6 g, contact T. Bunch, NAU; 1.1 g plus thin section, UHaw; main mass, 260 g, Radomsky.
