NWA 11375 Polymict Diogenite Meteorites for Sale
Location: Northwest Africa, exact location unknown.
Found: Purchased in May of 2017
Classification: Diogenite (polymict breccia)
Description: Breccia composed of angular mineral grains and rare pyroxene-chromite symplectite clasts in a sparse matrix. The predominant mineral is low-Ca pyroxene (exhibiting undulose extinction) with subordinate olivine (of several different compositions), chromite, metal, fayalite, and minor (<2 vol.%) exsolved pigeonite. Olivine (Fa9.7; Fa17.7; FeO/MnO = 36-40; N = 2), low-Ca pyroxene (Fs30.6Wo6.2, FeO/MnO = 28), orthopyroxene host (Fs45.8Wo1.6, FeO/MnO = 28), clinopyroxene exsolution lamella (Fs16.8Wo44.3, FeO/MnO = 21), orthopyroxene in symplectite with chromite (Fs14.1Wo0.8, FeO/MnO = 23), clinopyroxene in symplectite with chromite (Fs8.1Wo41.6, FeO/MnO = 21), fayalite (Fa85.2, FeO/MnO = 38), plagioclase associated with fayalite (An56.1Or2.0). Petrography and analysis by A. Irving.
