NWA 15169 est une météorite lunaire découverte en 2021 au Maroc près de Dakhla dans la zone de Wad Oum Sfia par Omar Ben Chaoud and Mouloud Oudinat.
NWA 15169 est une rare météorite lunaire (anorthosite).
C’est une très belle météorite lunaire très colorée proposée à un très bon prix.
Il y a une quinzaine d’années les météorites lunaires se vendaient presque 1000 euros le gramme !

Northwest Africa 15169 (NWA 15169)
Morocco
Purchased: 2021
Classification: Lunar meteorite (anorth)
History: Found by Omar Ben Chaoud and Mouloud Oudinat in the Dakhla, Wad Oum Sfia area. Later bought by Jean Redelsperger from Mohamed Elguirah in 2021.
Physical characteristics: Several stones: a complete 50 g crusted stone, and several gray fragments without fusion crust, the largest one being 52 g.
Petrography: (J. Gattacceca, B. Devouard, CEREGE) Brecciated igneous rock composed primarily of anorthitic plagioclase, and mm-sized poikilitic microgabbroic clasts with plagioclase chadacrysts set in olivine and pyroxene. Accessory minerals: metal, ulvöspinel, chromite. Barite, from terrestrial weathering, is present as veins.
Classification: Lunar (anorthosite). Contains microgabbroic clasts. Olivine, pigeonite and plagioclase are within the ferroan anorthositic suite (FAS) field defined by Warren (1993). Olivine has been altered on Earth, as indicated by the low analytical totals.
Specimens: Type specimen at CEREGE. Main mass with Jean Redelsperger.

NWA 15171 est une météorite rare de type mésosidérite.
Les mésosidérites sont des roches bréchiques contenant des composants silicatés et métalliques, les silicates sont principalement des fragments de roches ignées.

Adrar, Algeria
Purchased: 2022
Classification: Mesosiderite
History: Bought by Jean Redelsperger from Mohamed Elguirah in 2022.
Physical characteristics: Many brown ireggular stones without fusion crust.
Petrography: (J. Gattacceca, CEREGE) The rock contains similar abundances of silicate minerals (pyroxene, and plagioclase), and metal and its weathering products. Silicate grain size is about 200 µm. Plagioclase and low-Ca pyroene dominate over Ca-pyroxene. Fe,Ni metal and troilite have been mostly replaced by terrestrial weathering products.
