Huit fragments d’Erg Chech 003, une météorite carbonée CR2 d’Adrar, Algérie, pesant au total 16,31 g, vendus avec des certificats d’authenticité et de petits flacons cylindriques d’exposition.
Résumé assisté par IA
Description fournie par le vendeur
Offered for sale is a set of eight fragments of Erg Chech 003 (from less than 1 gram to 3.8 grams with a total weight of over 16 grams), a scarce CR2 carbonaceous chondrite recovered in Algeria in 2021. With an officially recorded total known mass of slightly over 1 kg, this meteorite ranks among the rarer carbonaceous chondrites available.
Erg Chech 003 represents far more than an uncommon meteorite. Its combination of rarity, scientific significance (showing signs of in-situ aqueous alteration which occured on its asteroid parent body), and limited availability makes it a highly desirable acquisition for collectors who focus on primitive Solar System material.
Erg Chech 003 (EC 003) 26°01.92’N, 1°36.66’W
Adrar, Algeria
Find: 2021
Classification: Carbonaceous chondrite (CR2)
History: Found in 2021 by Ali Mustapha near the town of In Zghmir. Later purchased in 2021 by Shun-Chung Yang.
Physical characteristics: Sample contains visible fusion crust. A slice taken of the sample reveals an assortment of chondrules and metal grains.
Petrography: (D. Sheikh, Cascadia) This sample is composed of chondrules (Primarily porphyritic Type I, Av. 1.3 mm, up to 2.5 mm, ~70 vol. %) set within a fine-grained, hydrous matrix (~30 vol. %). Metal occurs either as blobs within chondrules or as rims around chondrules.
Geochemistry: Type I Olivine (Fa1.7±0.4, range Fa1.0-2.3, n=21), Type II Olivine (Fa38.2, n=1), Low-Ca Pyroxene (Fs3.0±1.4Wo0.8±0.2, range Fs1.3-6.8Wo0.5-1.3, n=11). Average EPMA analytical totals in the matrix 81.9 wt. % (n=10).
Classification: Carbonaceous chondrite (CR2) based on texture, mineral compositions and low matrix analytical totals.
