El Hassan Ould Hamed 002 (EHOH 002) 25°54’48.0″N, 7°30’43.4″W
Tiris Zemmour, Mauritania
Find, possible fall: 2021 Nov
Classification: Ordinary chondrite (L4)
History: On November 6, 2021, at around 1 pm Saharawi people residing in the refugee camp of Dakhla (about 200 km south of Tindouf, Algeria) heard a strong sonic boom confirmed by many people in the neighboring countries of Mauritania and Western Sahara. A few days later, many meteorite fragments with fresh fusion crust have been recovered by meteorite hunters in northern Mauritania close to the Algerian border (Tindouf province). Mr. Salamu Ali purchased a 446 g fragment and submitted it for classification. Ziyao Wang owns an additional 5 kg.
Physical characteristics: Almost completely covered with fresh fusion crust. Cut surfaces reveal a fresh light grayish interior with minor orange halos around shiny metal grains.
Petrography: The meteorite shows a chondritic texture with well-defined, mostly rounded, packed porphyritic and barred chondrules (apparent mean diameter about 0.7 µm) in a fine-grained matrix that contains unaltered sulfides and FeNi metal.
Geochemistry: olivine: Fa24.2±0.1 (Fa23.9-24.4, n=11); low-Ca pyroxene: Fs20.2±0.2Wo2.1±0.1 (Fs19.9-20.6Wo1.9-2.2, n=11); Ca-pyroxene: Fs8.4±0.1Wo43.8±0.2 (Fs8.2-8.6Wo43.5-44.2, n=5); feldspar: An10.6±0.1Ab83.7±0.6Or5.7±0.6, n=4
