Taoudenni 002 22.9833, -3.4333 Gao, Mali Find: 2021 Classification: Martian meteorite (Shergottite) History: Found by a team of meteorite hunters just northeast of Taoudenni, Mali. A deal was brokered between the finders and Darryl Pitt with a Mauritanian meteorite and desert truffle hunter as the intermediary. Physical characteristics: This single boulder-like, smooth-contoured mass features a sweeping parabolic face truncated by a strikingly flat perpendicular surface. Fusion crust is absent on this abstract ventifact form; a gently-rippled surface texture is rendered in variegated earth tones under a pale green hue with ochre accents. A desert varnish covers the smooth stippling which has been determined to be the grains of pyroxene, olivine and maskelynite of which this mass is primarily comprised. A clear demarcation indicates the portions of the mass which rested above and below ground. Saw cut and broken surface reveal a medium-grained mixture of light gray, light green, and orange grains. Petrography: (C. Agee, UNM) This meteorite has the approximate modal abundances: 50% pyroxene, 25% olivine, 20% maskelynite, with accessory ilmenite, chromite, titanomagnetite, and troilite. Pyroxenes are igneously zoned with pigeonitic cores and augitic rims. Phenocrystic pyroxene grains often form cumulate masses up to several mm. Phenocrystic olivines are typically less than 1mm and have mild zoning profiles. Maskelynite is found primarily as acicular laths with typical dimensions of 0.1 × 1 mm. Geochemistry: (C. Agee, UNM) Olivine Fa45.9±9.3, Fe/Mn=54±2, CaO=0.17±0.06, NiO=0.05±0.01 (wt%), n=5; pyroxene Fs30.5±7.4Wo15.6±10.9, Fe/Mn=30±2, n=20; maskelynite An51.2±1.7Ab46.3±0.9Or2.5±0.8, n=6. Classification: Martian shergottite (olivine-pyroxene phyric basalt) Specimens: 22.26 g on deposit at UNM, Darryl Pitt holds the main mass. | ||||||||||||||||||||||||||||||||||||
