Description from the seller
Et Tamat 001 17°59'06.0''N, 0°01'12.0''W
Gao, Mali
Found: January 2021
Classification: Achondrite Mesosiderite
Mass: 145 g
History:
The meteorite was found in January 2021 in the Arkach region in eastern Mali, and was subsequently purchased by the major holders of the mass from a local meteorite dealer.
Physical characteristics: Numerous dark-brown fragments without fusion crust.
Petrography: The meteorite presents a dark brownish-red interior and is composed of silicate (about 50% by volume) and strongly altered metallic portions (about 50% by volume). The silicate fraction is mainly low-Ca pyroxene and calcic plagioclase, mostly compositionally zoned, up to 3 mm in size. The Ca-poor pyroxene is present as vesicular and lamellar exsolutions in the Ca-poor pyroxene. Minor phases are silica, Ti-chromite, FeS and Mg-merrillite. The metallic lithology is composed mainly of iron oxides and hydroxides; only a few taenite grains have been preserved. No olivine was detected in the studied section.
Geochemistry: low-Ca zoned pyroxene: Fs 29.7±2.5 Wo 3.8±0.5 (Fs 24.4-32.4 Wo 2.8-4.5, FeO/MnO=19-28, n=17); augite exsolutions: Fs 15.0±0.4 Wo 40.7±0.8 (Fs 16.0-16.8 Wo 39.2-41.4, FeO/MnO=16-18, n=5); calcic plagioclase: An 94.3±0.3 (An 93.8-94.6, n=8)
The shipment will be accompanied by a certificate of authenticity!
