Аннотация

An Ediacaran complex of dike rocks has been identified for the first time in the Yenisei Ridge orogen. These igneous rocks are represented by basic, intermediate and acidic variants and formed in the conditions of the transform active continental margin at the stages of its development before and during the interruption of subduction and slab breakoff. The rocks range from dikes of a picrodolerite–olivine dolerite–dolerite–quartz diorite–leucogranite association with ages ranging 626‒623 Ma (U‒Th‒U isotope data for zircons, SHRIMP-II method, this work) up to adakite–gabbro-anorthosite magmatism at the end of the Ediacaran (Vernikovskaya et al., 2017).
