New data on basal deposits of the Takata formation at the Yuzhnaya Rassolnaya diamond deposit (Perm region)

Abstract

The article presents a brief history of the study of the Takata suite in the Urals. The section of the basal deposits of the Takata formation in the Krasnovishersky diamond-bearing area at the Yuzhnaya Rassolnaya deposit is described. A granulometric study and quantitative mineralogical analysis of the heavy fraction of the gravelite matrix at the base of the Takata section were carried out. X-ray phase analysis was used to study the clay fraction. The authors made a conclusion about the alluvial genesis of the studied basal deposits of the Takata formation and about the erosion of ancient weathering crusts under the continental regime of development of the territory.
