Writeup from MB 110:

Northwest Africa 13972 (NWA 13972)

(Northwest Africa)

Purchased: 2021

Classification: Carbonaceous chondrite (CVred3)

History: The meteorite was acquired by the mass holder in Mauritania.

Physical characteristics: Brownish rock without fusion crust.

Petrography: Carbonaceous chondrite composed of large chondrules (mean diameter about 0.9 mm; up to 2 mm sized), CAIs (up to 3 mm sized), and olivine amoeboids all set into a fine-grained dark brownish to black matrix. Several chondrules show brownish staining due to terrestrial alteration. Opaque phases are metal and Ni-poor sulfides.

Geochemistry: Ni in sulfides 0.29±0.45 wt%, N=11

Classification: Carbonaceous chondrite (CVred3). Reduced subgroup based on low concentrations of Ni in sulfides (Gattacceca et al., 2020).
