About Britholite-(Y)Hide

Formula:
(Y,Ca)5(SiO4)3OH
Colour:
Reddish-brown, black.
Lustre:
Adamantine
Hardness:
5
Crystal System:
Hexagonal
Name:
First described as abukumalite by Hata (1938) from the Suishoyama pegmatite, Fukushima Prefecture, Japan. Later it was renamed as briotholite-(Y) as part of the changes in nomenclature for rare-earth minerals (Levinson 1966). It is named for its relation to britholite-(Ce) and the suffix "-(Y)" due to the dominance of yttrium in the composition.
A mineral in the Britholite Group of the Apatite Supergroup. A britholite with predominance of Y among the M site cations and OH > F. The
yttrian analogue of britholite-(Ce). A typically metamict mineral.
