Meteorite**NWA 032; Lunar Mare Basalt**0.111 gram frag. slice, Historic Lunar!!!

Description

Hello up for sale is NWA 032, an Ultra Rare Lunar Mare Basalt, one of the first NWA's and a Historic find!! This beautiful fragment slice weighs 0.111 grams,  has a soft polish to one side. 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 wid. This was one of the first Lunar Mare Basalt ever available to the public and originally was sold for ,000 per gram!!!! This is your opportunity to own a piece of history, only a few fragments are available, and very difficult to find this meteorite. It comes with 2 COA cards Streaming Meteorites and Mark Lyon and display case. Thanks for your interest and take care.

Morocco , near Algerian border
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.
