文摘

Archean and Devonian zircons are presented in kimberlite of the Nurbinskaya pipe. Found zircons with mosaic-like internal structure are the evidence of deformation. Mosaic zircons show difference in age within the grain, dating the deformation. Older zircon population and mosaic grains are crystallized from the same protolith. Recurrent activity in mantle formed various in age zircons and caused deformation.
