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!

History: Bought from Zaid Oualguirah in April 2019.
Physical characteristics: Stone with fusion crust. Interior is brown, with visible chondrules.
Petrography: (J. Gattacceca, CEREGE) Equilibrated ordinary chondrite with average plagioclase size below 50 µm. Matrix is scarce and inter-chondrule porosity is high, making chondrules well-delineated.
History: Found in september 2018 by Hammo Oulguirah. Bought in Agadir from finder.
Physical characteristics: Crusted stone with light grey interior.
Petrography: (J. Gattacceca, CEREGE) Highly recrystallized and brecciated chondrite. No relict chondrules was observed in the ~1 cm2 studied polished section. Plagioclase typical size 100 μm. Opaque minerals are Fe,Ni metal (mostly under the form of zoned taenite), FeS, chromite.
NWA 10153 is a very rare Martian meteorite of the nakhlite type.
To this date, only 27 meteorites of this type have been discovered.
A study has shown that nakhlites were imbued with liquid water about 620 million years ago and that they were ejected from Mars about 10.75 million years ago by an asteroid impact.
Martian meteorites are Martian rocks that were ejected from Mars by impacts and then fell to Earth as meteorites. The three best known types are shergottites (basaltic to lherzolitic igneous rocks, named after the Shergotty fall in India in 1865), nakhlites (clinopyroxenites or wehrlites, formed of cumulative rocks, and named after the fall of Nakhla, in Egypt, in 1911), and chassignites (cumulative dunitic rocks named after the fall of Chassigny, in France, in 1815).
Physical characteristics: A single stone with fusion crust. Cut surface reveals a light gray interior
Petrography: Main minerals are olivine, pyroxene (with typical grain size 100 μm), plagioclase (to 200 μm). The texture is recrystallized with triple junctions and lobate grains. Rare relict chondrules. Plagioclase is found as euhedral grains and as veins between the other silicates. Ca-phosphates to 200 μm. Chromite to 50 μm. Metal as small blebs or elongated grains in the olivine.
Geochemistry: Olivine Fa 32.0±0.4 (N=4). Orthopyroxene Fs26.4±0.2 Wo1.9±0.5 (N=3). Plagioclase An10.4Or5.1 (N=3). Chromite Cr#=0.88. Magnetic susceptibility log χ =3.55 (χ in 10-9 m3/kg).
Classification: LL7 based on texture, Ca content of orthopyroxene, and plagioclase size. Weathering grade W1.
Specimens: 6.8 g and a polished section in CEREGE. Main mass with Jean Redelsperger
The Chergach meteorite is an H5 type meteorite that fell in Mali on July 2, 2007.
In autumn and winter 2007, about 100 kg of meteorites were collected in Erg Chech, north of Taoudenni. The nomads reported that the stones fell after a cloud of smoke was seen and several detonations were heard over a wide area during the day in July 2007. The discoverer of the first meteorites was Mr. Ouled Bleila, who died in a car accident on his way home from visiting the Chergach field in October 2007. According to Tuaregs from Algeria who visited the falls site in September 2007, the elliptical falls field stretches over 20 km in a northeasterly direction. No fireballs were reported.
