It is a shergottite, the most common type of martian meteorites. Shergottites are mostly composed of basalts. Upon impact that ejected it from the Martian soil, the violence of the shock has changed the structure of some of its minerals, especially feldspars, which changed from a crystallized state to glass. By cutting slices of the meteorite NWA 2986, this new mineral called maskelynite is easily identified by its transparent appearance in the interstices of other minerals.
