Description

Like anatase and rutile, brookite is a titanium dioxide. It sometimes appears as stocky black crystals, but is more commonly known in its orange-red lamellar form.
Minerals from Magnet Cove, a rich baryte mining area in Arkansas, USA.
A specimen from the Hubin collection in Neupré, Belgium, delivered with its label.
