| Popis: | Type-chemical features of high-titanium magnezium-ferruginous micas of granulites, mafite-ultramafites, alkaline rocks, and carbonatites are considered. It is shown that genetically high-titanium micas are connected only with alkaline rocks and carbonatites. Chemical composition of high-titanium phlogopite-annite can be used at an assessment of Zr-Nb mineralization of metamorphic and magmatic rocks. |
