The Ob-Zaysan folded zone is a fragment of a single marginal-continental structure of the Siberian continent, made up of Paleozoic sedimentary and volcanogenic rocks (mainly black shale) and characterized by a common set of magmatic complexes and mineral systems. However, there are some differences which determine the geological and metallogenic specific features of the Irtysh-Zaysan and Kolyvan-Tomsk areas of the Ob-Zaysan folded zone. In the gold fields of these areas the main gold-sulfide mineralization (orogenic gold style) is controlled by sheared zones and is formed under tectonic compression in long-developing block structures.
