Northwest Africa 15016 (NWA 15016)

(Northwest Africa)

Purchased: 2022

Classification: Martian meteorite (Shergottite)

History: The meteorite was purchased from a meteorite dealer in Algeria.

Physical characteristics: Grayish to slighly greenish rock without fusion crust.

Petrography: The meteorite displays a coarse-grained diabasic texture predominantly composed of up to 800 µm sized irregularly zoned pyroxene and interstitial maskelynite. Maskelynite contains myrmekitic intergrowths of silica, Ca-pyroxene, and ilmenite. Minor phases include partly exsolved ilmenite, troilite, and merrillite. The meteorite is highly shocked and contains shock melt veins and pockets.

Geochemistry: complex zoned pyroxene: Fs_37.9±15.7Wo_27.7±9.1(Fs_19.8-65.7Wo_14.2-37.8, FeO/MnO=32±3, n=17); maskelynite: An_50.2±3.8Ab_48.0±3.3Or_1.8±0.5(An_45.2-55.9Ab_42.8-52.5Or_1.0-2.5, n=10)
