Abstract
Phenomena of hybridization were studied in the pluton "Sidorovsky Ural" located in the northeastern part of the Minusinsk basin. This pluton is the eastern end of a chain of essentially nordmarkite bodies, extending along the northern side of the Minusinsk basin at its junction with the Eastern Sayan. Spatially and genetically, the nordmarkite intrusions are closely associated with the Lower Devonian basic subalkaline and acid effusive rocks, with which they form a single magmatic association of the marginal part of the Minusinsk depression. In terms of depth, the nordmarkite intrusions belong to shallow-depth intrusions, geochemically characterized by a predominance of sodium over potassium and by rare-earth mineralization.
