| | GemRocks: Zoisite |
 | | That role falls to the zoisite-rich rocks in which red corundum is surrounded by green zoisite plus or minus a dark amphibole, usually referred to as hornblende, but in some records is reported as tschermakite (e.g., www-2.cs.cmu.edu). |
 | | The zoisite of these rocks is typically granular and tends to appear sugary in most rough. |
 | | Mineralogically, zoisite is a member of the epidote group, the other members of which are clinozoisite, epidote per se, piemontite, and allanite. |
