摘要
中上元古界云台群中的石英岩类、某些片岩类是含蓝晶石的层位。与蓝晶石共生的黄玉、天蓝石、磷钙铝石、叶腊石、金红石等矿物构成高压变质带里原岩为泥质、泥砂质的白片岩或类白片岩的一套矿物组合。它们将成为今后岩石学研究的新领域，同时也是今后寻找金刚石、刚玉、磷、镁等矿产的线索之一。
Quartzite and some shistose of Yuantai Formation of Middle Upper Proterozoic are kyanite bearing beds. The associated minerals are topaz, lazulite, gorceixite, pyrophyllite, rutile etc. which constitute a suit of mineral assemblage of muddy or muddysandy muscovite schist in high pressure metamorphic belt. The result develops new field for petrological research and provide clues for the prospecting of diamond, topaz, phosphorous and magnesium deposits.
