Writeup from MB 110:

Northwest Africa 13766 (NWA 13766)

(Northwest Africa)

Purchased: 2016

Classification: Carbonaceous chondrite (CVred3)

History: The meteorite was initially purchased from a dealer in Rissani, Morocco, and subsequently bought by the main mass holder.

Physical characteristics: Dark grayish individual partly covered by fusion crust.

Petrography: Carbonaceous chondrite composed of large chondrules (mean diameter about 0.9 mm; up to 3 mm sized), CAIs (up to 6 mm sized), and olivine amoeboids all set into a fine-grained almost black matrix. Several chondrules show brownish staining due to terrestrial alteration. Opaque phases are metal often occurring as blebs in chondrules, sulfides and their respective alteration products.

Geochemistry: Ni in sulfides <0.55 wt%, N=11

Classification: Carbonaceous chondrite (CVred3). Reduced subgroup based on low concentrations of Ni in sulfides.
