Chwichiya 002 is an ordinary carbonaceous chondrite of type C3.00 ungrouped, it is the most primitive type that has ever been found in this date, it has not undergone any hydrated phase and no heating before its expulsion from the parent body.
This meteorite is perhaps one of the most important meteorites of all times, no doubt that the knowledge of our solar system will advance thanks to it.
It was discovered in the Western Sahara. A must for a collection!
Nwa 13512 is an Aubrite meteorite discovered in Morocco near Boudnib in 2019.
I this date only 72 meteorites of this type have been classified.
It is a rare type of meteorite, difficult to find on the market.
The name Aubrites is linked to the fall of a meteorite in Aubres, France in 1836. They are composed mainly of orthopyroxene to enstatite.
History : Three visually-similar specimens (total weight 105 g)
found together near Boudnib, Morocco were purchased by Mohammed Hmani in December 2019.
Petrography: (A. Irving, UWS and P. Carpenter, WUSL) The specimen has a mean grainsize of ~400 µm and is composed predominantly of equant grains of enstatite with subordinate sodic plagioclase and accessory altered Si-bearing kamacite, altered Cr-troilite and schreibersite.
Geochemistry: Enstatite (Fs0.2±0.0Wo0.6-0.7, N = 3), plagioclase (Ab91.4An2.6Or6.0; Ab76.4An21.4Or2.3; N = 2), kamacite (Si = 1.5 wt.%, Ni = 7.9 wt.%).
Classification: Aubrite.
Specimens: 20.5 g including one polished thin section at UWB; remainder with Mr. M. Hmani.

In April 2013, I prospect for meteorites in Morocco with a group of friends.
After an unsuccessful search for the Martian meteorite NWA 7397, we met a group of meteorite hunters who took us to the site of a new meteorite discovery on April 18.
The day before, a meteorite of 219 grams was found, the meteorite hunters thought at first that this meteorite was a lunar meteorite.
It finally turns out that this meteorite is not a lunar meteorite but an eucrite.
Other fragments will be discovered later including the supposed main mass (332.85 grams) on April 24, 2013 by Lahcen Oukhouya meteorite hunter and native of Smara.
I was able to acquire the main mass of this fall, as well as 8 other fragments through Ali Oulmaleh (meteorite dealer in Erfoud) and Mohamed Elguirah (meteorite hunter in Tan Tan).
This meteorite was found 120 km northeast of Laayoune in the Western Sahara, in a place called Chwichiya (little fez) in reference to the mountain seen in this region in the shape of a fez.
Chwichiya is an area rich in meteorites, and in particular achondrites, 4 different achondrites have been discovered within a radius of 6 kilometers!
This meteorite is a brecciated eucrite, composed of 11 pieces for a total of 1038 grams. This meteorite has the particularity to have two different textures.
Petrography: Breccia with coarse basaltic clasts in a fine-grained matrix. The matrix has a doleritic texture with plagioclase grain size of several mm. Dominant minerals are exsolved pyroxene and mm-sized calcic plagioclase laths. Minor phases include chromite, silica, Ca-Phosphate, troilite and metal.
