Lunar Meteorite (feldspathic breccia)
History: Purchased from a meteorite dealer by the owner, in Erfoud, April 2017.
Physical characteristics: Two stones (127 and 178 g) with no fusion crust. The fresh interior exhibits white angular clasts in a medium-gray matrix.
Petrography: (J.-A. Barrat, IUEM) Breccia composed of angular mineral fragments and some olivine noritic clasts in a finer grained matrix. Minerals are anorthite, olivine, low-Ca pyroxenes, chromite, troilite and kamacite.
Geochemistry: Anorthite clasts An96.0±0.2 (N=6). The compositions of the phases from a noritic clast are: olivine Fa53±0.3, Fe/Mn=112±13 (N=9), anorthite An95.0-95.8, and pigeonite with augite exsolutions (respectively Fs43.2±0.6Wo4.8±0.8, Fe/Mn=65±5 (N=11), and Fs20.8±0.8Wo39.8±1.8, Fe/Mn=60±16 (N=3.
Classification: Lunar (feldspathic breccia)
Specimens: 21.5 g including a polished thick section.
