Dependence of mineral associations of crystal nests of the Subpolar Urals on the chemical composition of the host rocks
Abstract
Most researchers of rock crystal deposits of the Subpolar Urals believe that the components that make up the nest minerals are carried by hydrothermal solutions from the magmatic chamber. Let us see to what extent this widespread opinion is confirmed by the actual material during a more or less detailed study of the composition of the host rocks and crystal nests. The striking similarity of the bulk chemical composition of the minerals of the crystal nests and the host rocks is striking even at a cursory acquaintance with chemical analyses. Chemical analyses show that the minerals of crystal nests of the Subpolar Urals consist of the following components: SiO₂, Al₂O₃, FeO, MgO, CaO, Na₂O, K₂O, Fe₂O₃, TiO₂, MnO, H₂O and CO₂. All these components are also included in the rocks hosting the crystal nests. Characteristically, the quantitative ratios between the above components are almost identical both in the total composition of the nest minerals and in the rocks hosting the crystal nests.
