Zircons from sediments in contact with the granitoids of the Man’khambo massive (Northern Urals)

The morphology and inner structure of zircon crystals from gravelites and sandstone have been presented. They were lithologically and geochemically related to Telposskaya Formation and contact with granitoids of Man’khambo massif. It was determined that these rocks were dominated by angular zircon crystals of two types, bipyramidal (type 1) and elongated-prismatic (type II), which are different by color and transparency. Zircons of type I were characterized by zonal inner structure. Chemical variations were not found in the zircons of these types.
