Hydrogarnet

This page is currently not sponsored. Click here to sponsor this page.
Undifferentiated hydrogarnet.
Very small to small hydrogarnet components are observed in many garnets; these components reflect different substitution schemes (Geiger & Rossman, 2018).

See Grossular-Katoite Series.
