Abstract. From Pb-isotope age estimates of protoliths in sources of Cenozoic volcanic rocks and older dikes and sills, as well as Pb age estimates of galena from ore deposits, we define events of the early, middle, and late geodynamic epochs of the Earth's evolution in the Gargan zone of Eastern Sayans. We connect the tectonosphere development in the early geodynamic epoch with impact events of the Earth in the Hadean and Archean, in the middle one – with the Great Oxidation event in the Early Paleoproterozoic, and in the late one – with tectonic integration of the Gargan zone into the basement of the Tuva-Mongolian microcontinent in the Neoproterozoic and early Paleozoic. The conclusions obtained serve as a basis for identifying the Gargan-type continental tectonosphere.
Keywords: mafic rocks, magmatic sources, Gargan zone, Cenozoic, Neoproterozoic, Paleoproterozoic, Archean, trace elements, Pb isotopes.
