Martian Nakhlite - Mineral fluorite mineral sphere with some areas showing aMined from: Northwest Africa Description: NWA 15200 is a Martian nakhlite meteorite, an augite rich igneous rock formed from volcanic processes on Mars. With a total known weight (TKW) of 196 grams, this specimen represents a relatively rare class of Martian meteorites that crystallized from slowly cooling lava flows or shallow intrusions. Nakhlites are characterized by their coarse grained augite crystals, which formed in a stable magmatic
