Lunar Meteorite - Interactive 3D Model
NWA 15368 - Lunar Fragmental Breccia
Petrography: This meteorite is a clast-rich polymict breccia with subhedral lithic fragments embedded in a fine-grained groundmass. Fragmental clasts sizes range from <0.1 mm to >6 mm and are primarily comprised of plagioclase, low-Ca pyroxene, pigeonite, augite, and olivine. Minor phases include kamacite and ilmenite. This meteorite is shocked with impact melt textures present.
