Abstract The crystal chemistry of viridines and kanonaite, (Al 1-x-y Mn 3 x + Fe 3 y + ) 2 (OǀSiO 4 ), has been evaluated with special reference to the behavior of Mn 3+ in this andalusite type structure. Five natural samples (from Ultevis: x = 0.012, y = 0.028; from Yakutia: x = 0.076, y = 0.046; f...
