Aluminum rich silicates exposed to high pressures of 4 kilobars or more. Again, this information is available on the Internet in much mote detail.

Kyanite forms in metamorphosed schists and gneisses, and less commonly in granite pegmatites. - See more info on Kyanite at: http://www.minerals.net/mineral/kyanite.aspx
