Pollucite is a zeolite mineral with the formula (Cs,Na) 2 Al 2 Si 4 O 12 ·2H 2 O with iron, calcium, rubidium and potassium as common substituting elements. It is important as a significant ore of caesium and sometimes rubidium .

Pollucite may probably be (as is analcime) cubic, tetragonal, orthorhombic, monoclinic or triclinic, depending on ordering. Data courtesy of the American Mineralogist Crystal Structure Database.

2024年11月26日 · Pollucite is a rare mineral, primarily found in pegmatitic deposits, where it is associated with other rare minerals. Major sources of pollucite are in Canada (notably in Ontario), Afghanistan, Zimbabwe, and Brazil. It forms in hydrothermal environments, especially in veins and pockets within granite and pegmatite rocks.
