'Braunite-II'
Formula: CaMn3+14(SiO4)O20
Description: Braunite II was first discovered in 1945 at Black Rock and described as ferrianbraunite. The phase was renamed braunite II by De Villiers and Herbstein in 1967 and its crystal structure was determined by De Villiers in 1980. Metallic-grey braunite II crystals have come from Wessels, Black Rock (up to two centimetres) and N’Chwaning II. The crystals are typically bipyramidal with complex terminations. In 1995, crystals up to three centimetres were found at Wessels mine, and a few very rare larger crystals were also collected at the time. These were associated with andradite garnet, hausmannite and occasionally yellow ettringite. Braunite II is not listed as a recognised species in the IMA RRUFF database. See De Villiers (1945), De Villiers and Herbstein (1967), De Villiers (1970), De Villiers (1980) and De Villiers (1989) for details.
