Реферат:	eng: By applying the 40Ar/39Ar-dating method, age estimates for phlogopites of mantle xenoliths with different parageneses from the Udachnaya and Mir kimberlite pipes (Yakutia, Russia) were obtained. The oldest ages determined are 2.6-2.3 Ga, which far transcends the Paleozoic age of kimberlite entrainment. The phlogopite formation of these ages reflects ancient metasomatic events following rearrangement processes in the mantle in the Archean-Early Proterozoic, particularly during and after accretion of the Pangea-0 super-continent. A multistep age spectrum of UV162/09 was obtained from several generations of phlogopite and indicates a later multistage metasomatic process taking place in the mantle under Udachnaya pipe. Several stages of mantle metasomatism of various ages and scales are detected within the Siberian platform. © 2013 Pleiades Publishing, Ltd.
