Classification: Chondrite CM2 S1/W-low |
Place/Time: 2018 in Algeria
Physical characteristics: Almost black individual partly covered with fusion crust.
Petrography: Brecciated carbonaceous chondrite composed of chondrules (mean diameter about 0.3 mm), chondrule pseudomorphs, CAIs, and mineral fragments set into abundant Fe-rich matrix. Many of the components are surrounded by fine-grained dust rims. The fine-grained almost black meteorite matrix consists of abundant Ca-carbonates, sulfides and phyllosilicates.
All slices cut into 2mm thickness to reduce weight and maximize surface area. Under reflective light matrix show many different kind inclusions like on photo above.
