- Аннотация: The geological position, morphology of serpentinite bodies, limitation of ophiolite occurrences by faults, fragments of host metamorphic rocks within the Stanovaya complex of ophiolites, the character of metamorphism, the high deformation of rocks of both ophiolites and sequences at the contact zone, and mineral parageneses of secondary transformations point to the introduction of the Stanovaya ophiolites into the deeply metamorphosed Faddey Block of the Northeastern Taimyr, rather than to their obduction. The results of modeling showed that fragments of the oceanic crust introduced into the metamorphosed complexes of the continental crust during the collision may have dual origins, that is, from the primary oceanic crust, and from the newly formed crust of the back-arc basin. A detailed analysis of the chemical composition of the Stanovsky ophiolites indicates that they were formed in the suprasubduction setting of a back-arc basin, which supports the possibility of the second scenario.
