A type specimen was submitted for analysis to Northern Arizona University (J. Wittke and T. Bunch), and NWA 4969 was classified as a new brachinite. This brachinite might be paired with other brachinites found in Northwest Africa during a similar timeframe (e.g., NWA 4042, 4872, 4874, 4882 [the largest brachinite mass known], and 6349).

The term is also applied to icy bodies, in which case it is composed of ices, frozen gases, and accumulated meteoritic material.
