Description
Mined 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 environment before being altered by fluids on Mars.
What makes nakhlites particularly important is the evidence they preserve of water-related alteration on Mars. Secondary minerals and textures within the rock suggest interaction with liquid water after formation, offering valuable insight into the planet’s past environmental conditions. Like other Martian meteorites, NWA 15200 was ejected from Mars by a large impact event and eventually landed in the Sahara, where arid conditions helped preserve it.
Chemical Composition: Dominantly augite (Ca(Mg,Fe)Si₂O₆) with minor olivine ((Mg,Fe)₂SiO₄), feldspathic glass (maskelynite), and accessory minerals; rich in Fe, Mg, Ca, Si with trace elements.
