Northwest Africa 14212 (NWA 14212) Algeria Find: 2019 Classification: HED achondrite (Eucrite, melt breccia) History: Found near Adrar Algeria in 2019. Purchased in March 2021 by Roberto Vargas and Norman Lebron Jr. from a meteorite dealer in Morocco. Physical characteristics: Sample contains visible fusion crust. A slice taken of the sample reveals an assortment of light clasts set in a darker matrix. Petrography: (D. Sheikh, Cascadia) This sample is composed of up to 2 cm sized sub-angular to sub-rounded eucritic clasts containing zoned, equant pyroxene and elongate calcic plagioclase (some cores partially maskelynized) set within a melt rock matrix that contains vesicles. Accessory phases include ilmenite, Ti-bearing chromite, and SiO2-rich glass. Geochemistry: Low-Ca pyroxene (Fs63.9±1.1Wo2.4±0.6, range Fs61.8-67.1Wo1.5-3.7, Fe/Mn=30±4, n=31), Pigeonite (Fs60.0±0.1Wo8.3±0.6, range Fs59.9-60.1Wo7.9-8.7, Fe/Mn=31±1, n=2), Augite (Fs29.2±1.3Wo42.1±1.1, range Fs27.6-31.2Wo40.1-43.5, Fe/Mn=29±3, n=10), Calcic plagioclase (An87.8±2.8, range An83.6-92.5, n=16). Classification: HED Achondrite (Eucrite-melt breccia). Specimens: 21 g and a thin section at Cascadia; main mass with Roberto Vargas. | ||||||||||||||||||||||||||
