Metamorphic environments
Glucine occurs as 10-50 micron sized needles and platy crystals
(Mindat).
Localities
At the type locality, the Boevskoe Be deposit (Boevka; Severnoye), Kaslinsky District, Chelyabinsk Oblast, Russia,
glucine occurs as segregations in
mica-fluorite
greisen in illite rocks.
Associated minerals include moraesite,
fluorite, rutile,
limonite, quartz and
mica-clay minerals
(HOM).
