Find: January 2008
Mass: 57.2 g
Achondrite (lunar, feldspathic fragmental
stone of 57.2 g found by Michael Farmer and later sold to Philip Mani.
characteristics: The meteorite lacks an obvious fusion
crust but has the frosted, ablated exterior typical of Omani lunar stones. The
interior is light brown with few fractures, and terrestrial weathering is

The meteorite is a fragmental breccia composed of a variety of lithic
clasts (37 mm) and mineral fragments (0.30.4 mm) of olivine, plagioclase,
augite, and pigeonite set in a fine-grained matrix with some glass veins.
Lithic clasts include feldspathic granulitic breccia (plagioclase matrix
with interstitial grains of granoblastic olivine), spherulitic basalt
consisting of dominantly lath-shaped plagioclase and
pyroxene, fragmental breccia with 0.30.4 mm clasts of plagioclase,
olivine, augite, and pigeonite set in a fine-grained light-brown/gray
matrix, and a granophyre composed of plagioclase, pigeonite, chromite, and
ilmenite. No regolith components (glass spherules) have been identified.
Very minor FeNi metal.
Feldspathic granulitic breccia: olivine (Fa20.937.2, FeO/MnO =
73115), plagioclase (An94.597.7 Or0.00.3); basaltic
clast: 60.0% plagioclase (An94.596.7 Or0.20.5),
34.8% orthopyroxene (Fs41.747.1 Wo2.53.9, FeO/MnO =
55.259.4), 3.9% augite (Fs14.926.6 Wo30.741.9,
FeO/MnO = 46.362.5), 0.3% ilmenite, fragmental-breccia clast: plagioclase
(An96.6 Or0.4), olivine (Fa35.439.3,
FeO/MnO = 8295), augite (Fs16.416.9 Wo38.939.8,
FeO/MnO = 40.641.0); mineral fragments: plagioclase (An93.998.6
Or0.00.6), olivine (Fa17.462.5, FeO/MnO =75101),
augite (Fs10.351.4 Wo21.442.4, FeO/MnO =
