Erg Chech 002 est une météorite de type achondrite trouvée en Algérie en 2020.
Ce qui fait la particularité de cette météorite c’est qu’elle ne ressemble à aucune météorite connue à ce jour et que nous ne savons rien du corps parent dont elle est issue.
Cette météorite est datée de 4.565 milliards d’années (plus ancienne que notre Terre), elle a été formée au début du système solaire.
C’est la plus ancienne roche magmatique du système solaire connue à ce jour !
Cette météorite a également la particularité d’avoir de grands cristaux verts de pyroxène.
Lahmada 048 est une météorite de type achondrite ureilite de seulement 59 grammes découverte dans le Sahara Occidental dans une zone de concentration appelée Lahmada.
Elle a été découverte le 23 septembre 2020 par Brahim Elguirah.
Lahmada 048 contient certainement des diamants au vu des difficultés à la couper.
Les diamants, qui font rarement plus de quelques micromètres de diamètre, sont probablement le résultat d’ondes de choc à haute pression produites par la collision du corps parent des ureilites avec d’autres astéroïdes.

Lahmada 048 27°24’20.78″N, 9°51’13.07″W
Saguia el Hamra, Western Sahara
Find: 2020 Sep 23
Classification: Ureilite
History: The meteorite was found by Brahim Elguirah. The meteorite was bought by Jean Redelsperger from Zaid Oualguirah in 2020.
Physical characteristics: A single dark brown stone
Petrography: (J. Gattacceca, CEREGE) Aggregate of blocky olivine grains (grain size 800 µm) with reduced margins. Metal, originally present along olivine rims, is almost entirely replaced by terrestrial weathering products. Contains a significant amount of carbon material, likely diamonds in view of the extreme difficulty to saw the rock.
Geochemistry: Olivine Fa21.9±0.4, CaO 0.36±0.02 wt%, CrO3 0.65±0.02, FeO/MnO = 53.4±7.9 (n=4). Olivine rim Fa5.1 (n=1).
Classification: Ureilite
Specimens: Type specimen at CEREGE. Mais mass with Jean Redelsperger.
History: Bought by Jean Redelsperger from Lahcen Ait Ha in Erfoud in January 2015.
Physical characteristics: Eight irregular gray fragments without fusion crust. Chondrules are clearly visible at the surface. Cut surface shows closely packed large chondrules, with little weathering.
