Ouadane 001        20°28’07"N, 10°54’29"W

Adrar, Mauritania

Find: 8 Apr 2019

Classification: Ordinary chondrite (H5)

History: A single stone weighing 174 g was found by Giovanni Miceli in Mauritania during a tourist tour with local guides and sent to MSN-FI for classification

Physical characteristics: The main mass is almost completely covered by brown fusion crust.

Petrography: (V.Moggi Cecchi, L.Fabrizi, G.Pratesi UniFi): The thin section shows an equilibrated chondritic texture. Various chondrule types (PP, PO and BO) are visible, 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 scattered in the matrix as individual grains in the matrix or rimming chondrules

Geochemistry: EMP (V.Moggi Cecchi, L.Fabrizi, G.Pratesi UniFi); Olivine in both chondrules and matrix (Fa18.9±0.4Fo81.1±0.4; Fe/Mn = 33.1, n=9); low-Ca pyroxene in both chondrules and matrix (Fs16.7±0.3En82.2±0.3Wo1.1±0.2; Fe/Mn 21.7, n=17);

Classification: Ordinary Chondrite (H5); S2; W3;

Specimens: The main mass, weighing 153 g, is owned by Giovanni Miceli; the type specimen, weighing 20.2 g , and one thin section are on deposit at MSN-Fi (Inventory # I-3648).
