About Garnet SupergroupHide

Formula:
X3Z2(TO4)3
X = Ca, Fe, etc., Z = Al, Cr, etc., T = Si, As, V, etc.
Crystal System:
Isometric
Name:
Named from granatum (a pomegranate) for its resemblance to seeds of this fruit.
A group of cubic and pseudocubic nesosilicates, arsenates, vanadates and members with TO4 groups where T = Al, Fe3+, Te.
The current nomenclature was established by Grew et al. (2013).

Found in many rock types.

Note: Garnet group, synonymous with the colloquially used term garnet, is a group name encompassing the very common silicate garnets (almandine, spessartine, grossular, andradite etc.).
