Writeup from MB 110:

Northwest Africa 13602 (NWA 13602)

Algeria, (Northwest Africa)

Find: 2018

Classification: Ordinary chondrite (H3)

History: A single stone weighing 66 g was found by an anonymous finder in Western Sahara and purchased in 2018 at the Verona Mineral Fair by Lucian Cojocaru.

Physical characteristics: The main mass displays clear traces of stained fusion crust.

Petrography: (V. Moggi Cecchi, L. Fabrizi, G. Pratesi, UniFi): The thin section displays a marked chondritic texture, with various chondrule types (PP, PO and BO), sometimes rimmed with metal, set in a fine grained matrix. Olivine is rather inhomogeneous, while orthopyroxene is more homogeneous. Iron oxides, Fe-Ni alloys and troilite are the main opaque phases and can be found as individual grains scattered in the matrix or rimming chondrules.

Geochemistry: EMP (V. Moggi Cecchi, G. Pratesi, UniFi); Olivine in both chondrules and matrix (Fa16.1±4.0; n=31; Fe/Mn = 41.6); low-Ca pyroxene in both chondrules and matrix (Fs14.1±1.7En85.0±1.6Wo0.9±0.2; n=24; Fe/Mn = 19.5).

Classification: Ordinary Chondrite (H3); S1; W4

Specimens: Lucian Cojocaru owns the main mass, weighing 66 g; the type specimen, weighing 16.7 g, and one thin section are on deposit at MSN-FI (Inventory # I-3618)
