Formula:
RbLi2AlSi4O10(F,OH)2
Member of:
Mica Group
Seems to be the Rb (rubidium) analogue ofpolylithionite.fluorophlogopite. Co-described withsokolovaite, Cs-dominant micas -UM2003-27-SiO:AlCsFFeHLi andUM2003-28-SiO:AlCsFFeHMg - and anotherrubidium-dominant mica,UM2003-31-SiO:AlHLiRb.

Chemically very similar to another Rb-Li-mica,voloshinite.
