Writeup from MB 113:

Northwest Africa 16395 (NWA 16395)

(Northwest Africa)

Purchased: 2023

Classification: Mesosiderite

Physical characteristics: Dark brown stone

Petrography: (J. Gattacceca, CEREGE) Recrystallized igneous rock with triple junctions. Main minerals are pyroxene (to 200 µm), and plagioclase 60 µm in size. Opaque minerals are FeNi metal and troilite, and their weathering products. Silica polymorph and merrillite are observed. Despite pervasive weathering, the magnetic suscpetibility (log χ (× 10-9 m3/kg)=5.16) indicate an original high metal content on the order of a few tens of vol%.

Geochemistry: Pyroxene Fs32.0±1.0Wo3.8±0.5, FeO/MnO 23.9±3.3 (n=6). Plagioclase An93.5±2.4Ab6.3±2.4Or0.2±0.1 (n=3).

Classification: Achondrite (mesosiderite)

Specimens: Type specimen at CEREGE. Main mass with Kuntz.
