Qued Mya 004 30.16758, 3.60573 Ghardaia, Algeria Find: January 2021 Classification: Lunar meteorite (melt breccia) History: Found approximately 80 km southeast of El Menia, Algeria in January 2021. Purchased by Jay Piatek from a meteorite dealer in 2021. Physical characteristics: Single stone with two visually distinct lithologies: 1) light tan-green colored fragmental breccia and 2) black vesicular melt-rock which forms sharp boundaries with and also intrudes the lighter lithology. Petrography: (C. Agee, UNM) Electron microprobe analysis and reflected microscopy of a polished mount show this meteorite to be a polymict melt breccia with an anorthositic norite host rock consisting of fine-grained orthopyroxene, augite, and olivine poikilitically enclosed in plagioclase. Domains of vesicular melt rock and very fine-grained minerals and rock clasts bound and intrude the host rock. Minor phases chromite and silica were detected. Geochemistry: (A. Ross, UNM) Olivine Fa16.3±10.8, Fe/Mn=86±13, n=10; low-Ca pyroxene Fs22.6±6.9Wo3.5±1.0, Fe/Mn=57±5, n=9; augite Fs8.5±8.6Wo44.7±1.8, Fe/Mn=44±6, n=3; plagioclase An94.0±1.9Ab5.5±1.7, n=6. Classification: Lunar (polymict anorthositic norite melt breccia), nomenclature based on Stoeffler et al. (1980). The Mg# of olivine and An-content of plagioclase of this meteorite are consistent with that of the Apollo Lunar Mg-suite (Warren, 1993). Specimens: 20 g on deposit at UNM, Jay Piatek holds the main mass. | ||||||||||||||||||||||||||||||||||||
