The Nepluyevka pluton is the Early Carboniferous polyphase batholith situated in the East Ural zone. The batholith is subdivided into 4 phases ranging from basic to felsic in composition. The pluton formed during the Early Sudetian orogenic phase of the East Ural zone, which was characterized by a complex alternation of pure and sub-simple shear kinematic settings over its’ duration. Evidently, this alternation was connected with changes in the kinematics of the subduction zones preceding the Late Visean collision of Laurussia and Kazakhstania. These transformations had defined the characteristic features of the tectono-magmatic evolution of the southern part of the East Ural zone. Thus, their investigation is crucial for improving our understanding of the geological history of the Southern Urals.
