Object of study: sections of deposits of the Katav, Inzer and Minyar formations of the Karatau series of the Upper Riphean of the Avdyrdak anticline of the Alatau anticlinorium (Southern Urals). For the first time, detailed descriptions and sketches of sections of sediments of the Katav, Inzer and Minyar formations of the Avdyrdak anticline along the highway (80K-031) Ufa – Inzer – Beloretsk are presented. The study of deposits in natural outcrops and road quarries and excavations made it possible to clarify the material composition of the deposits in question, their ratio and thickness in the westernmost sections of the outer zone of the folded Urals. It has been established that the main features of the material composition and structure of the sections of the Katav, Inzer and Minyar formations of the Avdyrdak anticline are similar to the deposits of these formations in the reference and stratotype sections, which makes it possible to use the obtained data for stratigraphic correlation of sediments and reconstruction of sedimentation conditions in different parts of the paleobasin.
