The analyzed geological, geochronological and geochemical data allow separating the high-alkaline granitoids and syenites, including associating with them carbonatites and ultrabasic-basic intrusive rocks, into an integral Tartar complex, which was formed 675-630 mln. years ago. Such magmatic series are usually formed in anorogenic settings inside plates in association with plumes, upon riftogenesis or under conditions of active continental peripheries, when mantle melts are involved in magmatism.
