Norwegian kyanite quartzites - potential resources of high purity quartz?

Forkortet: This study represents an evaluation of Norwegian kyanite quartzite occurrences as potential deposits of high purity quartz raw material. Kyanite quartzites are rare fine-grained with 70 to 85 vol. % quartz and > 15 vol. % kyanite (Al2SiO5) which occur in Proterozoic supracrustal rock units. Kyanite quartzites form stratiform lens-shaped bodies, which can extend several kilometers.
