Formula:
RbFe2+3(Si3Al)O10(OH,F)2
Member of:
Mica Group
The Rb (rubidium) analogue of annite. Also the Rb-OH analogue of the co-described UM2003-27-SiO:AlCsFFeHLi. Also co-described with sokolovaite, another Cs-dominant mica - UM2003-28-SiO:AlCsFFeHMg - and another rubidium-dominant mica, UM2003-30-SiO:AlFLiRb.

Unique combination of elements (2024).
