Κορυφαίο "Black Beauty" NWA 11921 MARTIAN METEORITE Polymict Breccia Μετεωρίτης αχονδρίτης - 5×3×2 mm - 0.02 g - (2)
Northwest Africa 11921 (NWA 11921)
(Northwest Africa)
Purchased: 2018
Classification: Martian meteorite (polymict breccia)
History: Reportedly recovered in 2017 at the find site of NWA 7034 and purchased by Said Yousfi in 2018 from a local meteorite dealer in Zagora, Morocco.
Physical characteristics: Six black fragments with shiny crust.
Petrography: The meteorite is a polymict breccia composed of lithic and mineral clasts set into a very fine-grained clastic matrix. Lithic clasts include basaltic and impact melt types; most abundant mineral phases in clasts and matrix are pyroxene and feldspar, both of highly variable composition. Minor phases are ilmenite, magnetite, Ti,Cr-magnetite, and Cl-apatite. The meteorite’s high magnetic susceptibility reflects the high content of Fe-oxides and is in good agreement with data in Gattacceca et al. 2014.
Geochemistry: low-Ca pyroxene: Fs25.1±5.5Wo3.6±1.1 (Fs19.5-33.5Wo2.0-5.0, n=15, FeO/MnO=30-38); pigeonite: Fs39.9±12.0Wo8.0±2.7 (Fs25.6-52.3Wo5.6-12.4, n=10, FeO/MnO=30-40); Ca-pyroxene: Fs25.8±10.2Wo36.7±6.5 (Fs17.4-44.3Wo26.1-43.3, n=15, FeO/MnO=26-41); feldspar: An40.4±9.2Ab56.5±8.2Or3.1±1.9 (An29.0-49.3Ab48.3-66.7Or2.0-4.4, n=13)
Classification: Martian meteorite (polymict breccia). Likely paired with NWA 7034 and respective clan members.
