Environments
Hingganite-(Ce) occurs in pegmatites associated with quartz,
K-feldspar, albite,
zinnwaldite, cassiterite,
stokesite, fluorite,
chlorite and titanite (HOM), and as overgrowths
on hingganite-(Y)
(Webmin).
Localities
At the type locality, the Iwaguro Sekizai quarry, Tawara, Hirukawa, Nakatsugawa City, Gifu Prefecture, Japan, hingganite-(Ce) occurs
in a miarolytic cavity a in granite pegmatite associated with
quartz, feldspar,
mica, cassiterite,
stokesite, fluorite and
chlorite
(AM 75.432).
At Mount Ulyn Khuren, Altai Range, Mongolia, hingganite-(Ce) occurs in a granite pegmatite.
Other minerals found in the pegmatite include zircon, quartz,
kainosite-(Y), aegirine,
fergusonite-(Y)-β, ilvaite,
allanite-(Ce), magnetite,
fayalite and fluorite
(Minrec 35.2.178).
