NWA 10402 (Genomict Eucrite Breccia) SOLD OUT

NWA10402_1A small 48.66g stone was purchased out of Morocco in June of 2015. It was sent to Dr. Anthony Irving for classification and determined to be a Genomict Eucrite Breccia.  Slices were prepared my Montana Meteorite Laboratory and come polished on one side. Slices feature a busy matrix containing eucritic clasts. Each slice will come in a quality labeled meteorite display box.

Petrography as follows:

Fragmental breccia composed mostly of crystal debris plus some intact eucrite clasts (with intersertal and fine-grained, quench textures). Exsolved pigeonite in all components has the same optical properties. Other minerals are calcic plagioclase, silica polymorph, fayalite (Fa77.2; Fa89.0; FeO/MnO = 43-44), ilmenite and troilite, plus rare orthopyroxene (Fs39.0Wo3.1; FeO/MnO = 31), ferropigeonite (Fs77.1Wo15.8; FeO/MnO = 30) and Ni-free metal. Exsolved pigeonite consists of exsolution lamellae of clinopyroxene (Fs30.5Wo39.5; FeO/MnO = 31) within low-Ca pyroxene host (Fs57.8Wo6.7; FeO/MnO = 30).
