2. Brookite - Wikipedia

   en.wikipedia.org/wiki/Brookite

   Brookite is a brittle mineral, with a subconchoidal to irregular fracture and poor cleavage in one direction parallel to the c crystal axis and traces of cleavage in a direction perpendicular to both the a and the b crystal axes. [1] [3] [4] Twinning is uncertain. [3] [4] The mineral has a Mohs hardness of 5 + 1 ⁄ 2 to 6, between apatite and ...
