Writeup from MB 111:
Mont Tessalit 001 (MT 001) 20º46.0667N, 5º6.65E Tamanghasset, Algeria Purchased: 2021 Classification: HED achondrite (Eucrite, brecciated) History: Adrián Contreras Gómez (CRATER meteorites) purchased the samples from Ali Hnini in Tindouf, Algeria, on August 8, 2021. Physical characteristics: Many samples ranging in size from 1 to 789 g. The studied sample is ovoid in shape, light gray in color and appears to be brecciated. A cut sample, shows the interior has a cataclastic texture composed of mineral fragments. Petrography: Description and classification (A. Love, App) Sample is a cataclastic breccia composed of polycrystalline lithic clasts surrounded by coarse-grained (519 μm, n=50) fragments of plagioclase and pyroxene. Polycrystalline lithic fragments have abundant sulfide inclusions. Additional minerals are: phosphates, chromite and ilmenite. Geochemistry: (A. Love, App) low Ca pyroxene (Fs63.2±1.1Wo3.9±1.2, Mg#34.3±1.0, Fe/Mn=31.0±0.5, n=11); pigeonite (Fs60.7±2.5Wo6.7±2.2, Fe/Mn=31.2±0.6, n=8); high Ca pyroxene (Fs33.2±5.8Wo39.4±6.4, Fe/Mn=31.0±1.3, n=11); plagioclase (An91.5±2.0Or0.3±0.1, n=5). Classification: HED achondrite (eucrite) Textures and mineral compositions suggest sample is a monomict basaltic eucrite breccia. Specimens: Adrián Contreras Gómez (CRATER meteorites) holds the 789 g main mass. A polished thin section and an individual weighing 24.87 g are on deposit at App. | ||||||||||||||||||||||||||||||||||
