Erg Chech 002 #2 Achondrite Ung – 5,9 g

483,00

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 #4 Ureilite – 4 g

73,20

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.
