Anorthoyttrialite-(Y)
A valid IMA mineral species
This page is currently not sponsored. Click here to sponsor this page.
Formula:
Y4(SiO4)(Si3O10)
Crystal System:
Triclinic
Type Locality:
Known synthetic analogue (alpha-Y2Si2O7 or B-type Y2Si2O7, according to two different nomenclature schemes used in the literature).
Several lanthanoid analogues are known.
The name suggests it to be polymorphous with yttrialite-(Y) (?: confirmation needed).
