A manganese oxide mineral that is black or dark brown and forms in metamorphic rocks.
Named after German mineralogist Franz Braun in the 19th century; the -ite suffix denotes a mineral species.
Braunite is part of the rare hausmannite group of minerals, and it's one of the few minerals named after someone who didn't discover it—it was named in honor rather than discovery convention.
