Jdiriya 005 is an Aubrite meteorite of only 35.6 grams, discovered by Brahim Ikken in 2018 in Morocco.
A new theory carried by a French scientific team talks about the possibility of a link between the Aubrites and the planet Mercury.
To date only 76 such meteorites 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.

Jdiriya 005 27°33’23.45″N, 10°31’29.87″W
Saguia el Hamra, Western Sahara
Find: 2018
Classification: Enstatite achondrite (Aubrite)
History: Found by Brahim Ikken in 2018. Bought By Jean Redelsperger from Mohamed Elguirah in 2021.
Physical characteristics: Several irregular dark pieces.
Petrography: (J. Gattacceca, B. Devouard, CEREGE) Coarse-grained unbrecciated rock with granular texture made up primarily of enstatite (61 vol%) with typical grain size 5mm. No relict chondrules are observed. Other silicates are sodic plagioclase (3.6 vol%) with typical gain size 700 μm, and Si-rich glass. Opaque minerals (35 vol%), under the form of mm sized rounded grains, are all weathered except Zn-rich daubreelite that makes up 0.2 vol% of the meteorite.
Geochemistry: Enstatite Fs0.3±0.2Wo0.6±0.1, CaO 0.33±0.06 (n=6). Plagioclase An6.7±0.1Ab89.7±0.1Or3.6±0.1 (n=3). Daubréelite contains up to 6 wt% Zn.
Classification: Aubrite.
Specimens: Type specimen at CEREGE. Main mass with Jean Redelsperger.

Erg Chech 002 is an achondrite type meteorite found in Algeria in 2020.
The particularity of this meteorite is that it does not resemble any meteorite known to date and that we know nothing of the parent body from which it came.
This meteorite is dated 4.565 billion years (older than our Earth), it was formed at the beginning of the solar system.
It is the oldest magmatic rock in the solar system known to date !
This meteorite also has the particularity to have large green crystals of pyroxene.
