Abstract
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.
