Abstract
The article presents the results of U-Pb in zircon and Nd-isotope study of the adakite granites of the Goryachinsky pluton, exposed along the Baikal coast in the section of termination of the package of shear tectonic plates of the Baikal-Muya belt. The Early Cambrian age of granitoids, which is unusual for the Northern Baikal region, is 545 ± 6 Ma. According to the authors, new geological and isotopic data indicate the formation of the studied granitoids at the final stage of the Late Baikal shear tectogenesis, which caused the manifestation of adakite magmatism within the Baikal-Muya belt.
