Type Occurrence of StrontiofluoriteHide

General Appearance of Type Material:
cubo-octahedral crystals (up to 0.5 mm in diameter) and compact masses that cement fibrous aggregates of polezhaevaite-(Ce) in voids caused by leaching of burbankite crystals
Place of Conservation of Type Material:
Mineralogical Museum of St.
Petersburg State University and of the Geological and Mineralogical Museum of the Geological Institute, Kola Science Centre, Russian Academy of Sciences in Apatity, Russia (catalogue no. 6455).
Geological Setting of Type Material:
sodalite – microcline – aegirine – natrolite lens about 3 m in diameter within apatite-rich urtite at Mt. Koashva. This lens is a product of hydrothermal “natrolitization” of a primary pegmatitic mineral assemblage.
