Northwest Africa 14354 (NWA 14354)

Tantan, Morocco

Purchased: 2013

Classification: Ordinary chondrite (LL5)

History: A single stone weighing 6000 g was purchased by Giorgio Tomelleri at Tantan in 2013 and sold to Antonello Petriccione in 2019.

Physical characteristics: The main mass is partly covered by a black fusion crust. Broken surfaces reveal a fresh interior.

Petrography: (V. Moggi Cecchi, L.Fabrizi, G.Pratesi UniFi): The thin section displays an equilibrated chondritic texture, with various chondrule types (PP, PO and BO) set in a fine grained matrix. Both olivine and orthopyroxene are 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, L.Fabrizi, G.Pratesi UniFi); Olivine in both chondrules and matrix (Fa29.7±0.4Fo70.3±0.4; n=14); low-Ca pyroxene in both chondrules and matrix (Fs22.6±0.3En75.8±0.3Wo1.6±0.2; n=8);

Classification: Ordinary Chondrite (LL5); S3; W2;

Specimens: The main mass, weighing 5948 g, is owned by Antonello Petriccione; the type specimen, weighing 52 g , and one thin section are on deposit at MSN-FI (Inventory # I-3649).
