NWA 10403 (Polymict Diogenite Breccia) SOLD OUT

NWA 10403_2One stone weighing 96.24g was purchased out of Morocco in June of 2015. A sample of this stone was sent to Dr. Anthony Irving who determined the stone to be a Polymict Diogenite Breccia. Slices were prepared by the Montana Meteorite Laboratory and are polished on one side. They are thinly slices and feature a busy matrix filled with various diogenetic clasts (including green orthopyroxene and some eucritic). This diogenite is BEAUTIFUL! Each slice will come in a quality labeled meteorite display box.

Petrography as follows:

Fragmental breccia composed mostly of diogenitic clasts and debris, plus 22.4Wo2.1; Fs34.2Wo2.2, FeO/MnO = 34), calcic plagioclase, exsolved pigeonite, silica polymorph, chromite and troilite. Some exsolved pigeonite consists of exsolution lamellae of clinopyroxene (Fs29.2Wo41.5; FeO/MnO =30) within relatively ferroan host orthopyroxene (Fs58.3Wo3.85; FeO/MnO = 29). Other examples exhibit different, more magnesian lamellae/host pyroxene compositions: clinopyroxene (Fs21.8Wo39.6; FeO/MnO =19), host orthopyroxene (Fs48.5Wo2.2; FeO/MnO = 20).
