Top best answers to the question «Where does kyanite come from»

  • Kyanite is a metamorphic mineral that most often forms from the high pressure alteration of clay-rich sedimentary rocks. It is found in the schists and gneisses of regionally metamorphosed areas and less often in quartzite or eclogite. Kyanite's typical habit is a bladed crystal although it sometimes occurs as radiating masses of crystals.
  • Kyanite occurs both within the rocks itself or inside quartz lenses and veins. Other typical kyanite occurrence is in high pressure rocks called eclogites. Rarely, kyanite occurs also in some aluminum rich granites and pegmatites. Blue kyanite with dark staurolite crystals from Chironico, Switzerland.
