Purchased: March, 2021

Classification: Carbonaceous chondrite (CVox3)

History: The meteorite was purchased from a dealer in Morocco.

Physical characteristics: Dark-grayish rock without fusion crust.

Petrography: Carbonaceous chondrite composed of chondrules (mean diameter about 0.9 mm; up to 2 mm sized), CAIs (up to 4 mm sized), and olivine amoeboids all set into a fine-grained fresh appearing dark grayish matrix. Contains type I and type II chondrules. Opaque phases are abundant Ni-rich sulfides and very rare metal and troilite.

Geochemistry: Ni in sulfides 19.4±0.2 wt%, N=7

Classification: Carbonaceous chondrite (CVox3). Oxidized subgroup based on high concentrations of Ni in sulfide (Gattacceca et al., 2020).
