First U-Pb datings of detrital zircons from middle and upper paleozoic sandstones of the Polar Urals: Testing the regional tectonic models.

The article focuses on testing the tectonic evolution of the paleozoic sandstones of Polar Urals with the use of uranium-lead (U-Pb) dating of detrital zircons (dZr). It states that the samples were disintegrated manually using mortar and separated in bromoform. It mentions that the results show changes in the sedimentation settings which took place during the Paleozoic period.
