sample_remark Fine-grained, laminated rocks which contain on average 70-85 vol.% quartz and >15 vol.% kyanite. Their composition changes gradually into kyanite-poor or kyanite-free pyrophyllite/muscovite-bearing quartzites between the layers and towards the contact with the host rocks. The muscovite content in the rock commonly increases from the central part of the kyanite quartzite bodies towards the margin, from zero to up to 30 vol.%. The kyanite quartzites do not contain feldspar or biotite, which are common minor minerals in quartzites of sedimentary origin. Common accessories are rutile, muscovite, pyrophyllite, zircon, apatite, pyrite, and barytes. Description taken from data source publication
