South, Morocco
Find: 2023 Jun 20
Classification: Carbonaceous chondrite (CM2)
History: Found in Morocco near Chwichiya by Lahcen Ousaleh on June 06, 2023. Bought by Jean Redelsperger from Zaid Oualguirah in 2023 in Morocco.
Physical characteristics: Black stone with remanents of fusion crust. Cut surface reveals a dark fine-grained interior, with small chondrules.
Petrography: (J. Gattacceca, CEREGE) Chondrules with average apparent diameter ~200µm and chondrule fragments set in an abundant fine-grained iron-rich matrix. Opaque minerals are troilite, pyrrhotite, magnetite. Metal is found almost exclusively as inclusions in anhydrous silicates. X-ray diffraction analyses over a ~2 cm2 area on a polished section (D. Borschnek, CEREGE) reveal the presence of phyllosicilates and calcium carbonates, as typically observed in type 2 chondrites using the same experimental setup.
Geochemistry: Olivine Fa15.1±17.0, range Fa0.40-48.1 (n=7). Cr2O3 in ferroan olivine 0.40±0.18 wt% (n=6). Defocused analyses of matrix FeO 24.0±6.7 wt%, analytical total 76.1±5.0 (n=3).
Classification: Carbonaceous chondrite (CM2).
Specimens: Type specimen at CEREGE.Main mass with Jean Redelsperger.
NWA 15169 is a lunar meteorite discovered in 2021 in Morocco near Dakhla in the Wad Oum Sfia area by Omar Ben Chaoud and Mouloud Oudinat.
NWA 15169 is a rare lunar meteorite (anorthosite).
This is a very nice and colorful lunar meteorite offered at a very good price.
About fifteen years ago, lunar meteorites were sold for almost 1000 euros per gram !

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.
Jdiriya 003 is a meteorite of eucrite type of only 21.4 grams, it was discovered by Zaid Oualguirah in 2019 in the Western Sahara.
Howardite meteorites come from the asteroid Vesta, an asteroid between Mars and Jupiter.
I am selling the main mass of 15.7 grams, a unique piece !

Masse principale de Al Haggounia 008, chondrite ordinaire de 6,270 kg composée de 31 fragments.
Cette pièce a la particularité très originale d’avoir du lichen sur sa surface.
This meteorite was found in December 2013, 120 km northeast of Laayoune in the Western Sahara, in a place called Chwichiya (little fez) in reference to the mountain seen in this area in the shape of a fez.
Chwichiya is an area rich in meteorites. The pieces on sale have not been cleaned by choice, they are sold as they were found. These are the last pieces on sale!
Tanezrouft 081 is an ordinary chondrite of type H5. It was found by two Frenchmen A. Goueslain and J. L. Parodi in Algeria in 2003 in the Tanezrouff in Algeria.
At that time prospecting in Algeria was still possible.
Ksar Ghilane 021 is a meteorite of type H5 that I found with my travel friend Claude Roy during an expedition in Tunisia near the Oasis of Ksar Ghilane on February 13, 2020, just before the Covid 19 pandemic.
To date only 80 meteorites have been discovered in Tunisia.
