The comparative study of essentially hyperbasite (ultramafic) complexes of the Precambrian and Paleozoic appears to be a rational method of knowing the evolution of magmatism and metamorphism in the history of the formation and transformation of the Earth's crust.

Identification and meaningful analysis of indicator features of chemical composition and physical properties of rocks and ores in different structural-formational position and metamorphism of ultramafic complexes is essential for petrology and metallogeny.

With ancient uditramafites genetically or spatially associated practically interesting deposits of chromium, nickel, asbestos, talc and other minerals, so the identification of the main factors and features of the composition, which determine their mineralogenic specialization, is essential for formation analysis and for predicting ...
