Ghardaïa 001        32°43’43.1"N, 04°28’47.9"E

Ghardaia, Algeria

Purchased: November, 2020

Classification: Lunar meteorite (feldspathic breccia)

History: The meteorite was found south of El Guerrara, Algeria and subsequently purchased by the main mass holders.

Physical characteristics: Many grayish fragments some of which almost completely covered by fusion crust.

Petrography: Fragmental breccia composed of mineral fragments, basaltic, gabbroic, and impact melt clasts set in a fine-grained partly shock-melted groundmass often showing flow textures . Most abundant minerals are calcic plagioclase, olivine, and exsolved pyroxene. Minor phases include ilmenite, apatite, and FeS. Cracks are often filled with secondary calcite.

Geochemistry: low-Ca pyroxene: Fs21.3±0.5Wo4.6±0.9 (Fs20.4-21.8Wo3.0-6.1, FeO/MnO=48±4, n=9); Ca-pyroxene: Fs14.2±2.5Wo36.1±5.7 (Fs11.5-17.9Wo38.3-42.2, FeO/MnO=43±4, n=7); olivine: Fa28.4±0.6 (Fa27.5-29.1, FeO/MnO=84±7, n=11); calcic plagioclase: An96.8±0.5 (An96.3-97.7, n=9)
