摘要: The oxygen isotope composition of genetically related minerals is known to form a compact common field values, the area which depends only on variations in physicochemical parameters mineralforming medium. After mineral has formed, does not change if been transformed completely as result melting, chemical replacement, or other such reactions changing primary structure. Therefore, long served an indicator specific conditions for formation both and rocks general. We have studied samples corundum-bearing garnet‐amphibole‐phlogopite plagiogneiss Proterozoic age from Chupa Sequence Belomorian Complex Khitostrov deposit (Fig. 1).
