Writeup from MB 104:

Dhofar 1769 (Dho 1769)        18°20.4’N , 54°12.8’E

Zufar, Oman

Find: 2012 Oct. 28

Classification: Lunar meteorite

History: A single stone was found by an anonymous finder Oct. 28, 2012

Petrography: The anorthositic highland breccia contains clasts up to 1 cm, which are mainly anorthositic lithologies and crystalline impact melt breccias. It also contains glassy fragments, some of which are highly vesicular, veins, and impact spherules (mostly devitrified) embedded in a fine-grained, clastic matrix. The spherules indicate an origin at the lunar surface. Accessory minerals: ilmenite (abundant), troilite, FeNi metal (rare), and zircon (very rare).

Geochemistry: SEM-EDS-analyses revealed that plagioclase in the bulk rock is anorthitic with a mean of An93.4±5.1 (total range: An70-97; n = 32). Olivine is highly variable in composition Fo20-60 (mean: Fo40±9; n = 16; Fe/Mn = approx. 110 (EDS)). Low-Ca pyroxene also shows variable composition with Fs20-58En29-77Wo2.5-15 (mean: Fs37.5±10En54.6±10Wo7.8±3.3; n = 28; Fe/Mn = approx. 60 (EDS)). Some analyzed Ca-pyroxenes have Fs18-34En28-45Wo33-41. The meteorite is moderately weathered.

Classification: Lunar meteorite (anorthositic breccia)
