Writeup from MB 110:

Northwest Africa 13896 (NWA 13896)

(Northwest Africa)

Purchased: 2019

Classification: Lunar meteorite (feldspathic breccia)

History: In May 2019 at the mineral show in Chenzhou Ziyao Wang discovered on the bottom of a box with ordinary chondrites from northwest Africa some small strange stones and donated some material to Rainer Bartoschewitz. Some of these stones are of meteoritic and others of terrestrial origin.

Physical characteristics: Dark gray-brown stone of 8 g

Petrography: (R. Bartoschewitz, Bart) Breccia of lithic clasts (anorthositic, melt rock) and mineral fragments (pyroxene and minor olivine) up to 1.5 mm in fine grained matrix. Opaque minerals are ilmenite and chromite.

Geochemistry: (R. Bartoschewitz, Bart, P. Appel and B. Mader, Kiel) Olivine Fa25.5-35.5 (Fe/Mn 79-123; n=3); poor Ca pyroxene Fs25.3-25.6Wo3.8-4.0 (Fe/Mn 55-56; n=2); pigeonite En55Fs37Wo8 Fe/Mn 67; n=1); augite En31-49Fs15-40Wo19-44 (Fe/Mn 43-66; n=6); anorthite An95.0-97.4Or<0.2 (n=23). Ilmenite Mg=6 wt% (n=9). Magnetic susceptibility (R. Bartoschewitz, Bart) log χ (× 10-9 m3/kg) = 2.72

Classification: lunar meteorite (feldspathic breccia)

Specimens: 1.65 g on deposit at Kiel, 2 g and polished thin section with Bart
