NWA 15855 - CV3 Carbonaceous Chondrite

NWA 15855 is a CV3 Carbonaceous Chondrite recovered from Western Sahara and officially approved as a classified Northwest African meteorite. CV Chondrites are among the most visually distinctive Carbonaceous meteorites, known for their large chondrules, refractory inclusions, and dark primitive matrix. As a type 3 meteorite, NWA 15855 preserves relatively unequilibrated early solar system material, making it especially interesting for understanding the first solid components that formed around the young Sun.

NWA 15855 specimens can show a dark Carbonaceous matrix containing visible chondrules and calcium-aluminium-rich inclusions, often abbreviated to CAIs. These inclusions are among the oldest known solid materials in the solar system, while the chondrules record high-temperature melting events in the solar nebula. Its CV3 classification places it within the same broad family as famous meteorites such as Allende, though each CV meteorite has its own texture, alteration history, and collector character.

Studying NWA 15855 provides valuable insight into primitive Carbonaceous material, early solar system chemistry, and the formation of chondrules and CAIs. For collectors, it offers a scarce and scientifically important CV3 Carbonaceous Chondrite with recognised classification and strong visual appeal. Each specimen represents ancient asteroid material formed over 4.5 billion years ago, preserving some of the earliest building blocks of planetary formation.
