Qued Mya 002        30°08’25.4"N, 4°05’36.4"E

Ouargla, Algeria

Find: 2020 Nov 2

Classification: Carbonaceous chondrite (CM2)

History: Several pieces of the meteorite (totaling 127.4 g) were found November 2, 2020, in the area of Hassi Messaoud (In Salah, Algeria) and purchased from a dealer in Mauritania.

Physical characteristics: Small dark grayish to black individuals without fusion crust.

Petrography: The brecciated carbonaceous chondrite is composed of small (apparent mean diameter ~250 µm) chondrules, mineral fragments, TCI-objects, and rare CAIs. The chondrules are typically surrounded by fine-grained dust rims set into abundant fine-grained matrix. Sulfides and metals are accessory components.

Geochemistry: The olivines and low Ca-pyroxenes are highly variable in composition with Fa0.8-43.7 (mean Fa5.9±11.6; n = 23) and Fs0.9-3.7 (mean Fs1.6±0.7; n = 16). Oxygen isotopic composition (A. Pack, UGött): δ17O = -1.80, δ18O = 5.52 (all ‰).

Classification: Carbonaceous chondrite (CM2)
