A technique that allows to evaluate the degree of roundness of detrital zircon grains on a five-point scale according to the degree of preservation of the vertices, edges and faces of the crystals is presented. Based on the results of the degree of roundness of individual grains, the integral index SOs is calculated for a sample from various stratigraphic units. The obtained data makes it possible to determine the proportion of grains of different classes in different strata, to assess the degre
