Descripción del vendedor

Northwest Africa 17904 (NWA 17904)
Mauritania

Classification: Primitive achondrite (Lodranite)

History: The meteorite was purchased by Mohamed Ali Loud in July 2025 from a dealer in Nouadhibou, Mauritania .

Physical characteristics: Many dark brownish rocks with some fusion crust.

Petrography: The meteorite is an annealed breccia predominantly composed of large of to 7 mm sized olivine and low Ca-pyroxene grains separated by fine-grained regions consisting of 30 to 500 µm sized olivine, low-Ca pyroxene, and diopside crystals often meeting in 120 degree triple junctions. Minor phases include whitlockite, Ti-free chromite, FeS, and partly altered FeNi-metal. No feldspar detected.

Geochemistry: olivine: Fa12.0±0.5 (Fa11.3-12.7, FeO/MnO=51±6, n=10); low-Ca pyroxene: Fs11.8±0.2Wo1.2±0.1 (Fs11.5-12.0Wo1.1-1.3, FeO/MnO=31±2, n=10); Ca-pyroxene: Fs4.1±0.2Wo47.6±0.4 (Fs3.8-4.6Wo47.1-48.2, FeO/MnO=27±6, n=10)

Shock stage: low
Weathering grade: moderate
Classifier: A. Greshake, MNB
