Epidote
Well developed crystals of epidote, Ca2Al2(Fe3+;Al)(SiO4)(Si2O7)O(OH), crystallizing inside the monoclinic system, are of frequent prevalence: they're normally prismatic in dependancy, the course of elongation being perpendicular to the single plane of symmetry.
Kyanite
Kyanite is commonly found in aluminum-rich metamorphic pegmatites and / or sedimentary rocks and is commonly a blue silicate mineral. Cyanide in metamorphic rocks show better pressures than four kilobars. Although it is undoubtedly strong at stress and low temperature, it is generally sufficiently high under these conditions where water hobbyist, muscovite, pyrophyllite or kaolinite-containing aqueous aluminosilicates are replaced. Kyanite is also called disten, ranetite and cyanide.
Garnet
Garnet, any member of a group of not unusual silicate minerals that have comparable crystal structures and chemical compositions. They may be colourless, black, and lots of sun shades of red and inexperienced.
