The article developed a new stratigraphic scheme of metamorphosed Pre-Cambrian deposits of the Zholshoky area in the Atassu-Moiynty watershed. Particular attention was paid to the porphyroid strata, which were previously included on geological maps as part of the Upper Riphean Altynsyngan Formation, were we included in the Kabantau Formation. Also noticed the relationship of the Kabantau Formation with the underlying porphyroids of the Urkendeu Formation, where the quartzites and shales included in these formations are generally similar, and the porphyroids in these formations are distinguishable in color and structural-textural characteristics and the petrochemical features of porphyroids of these two formations are given. The conducted studies have made significant adjustments to the schemes for stratigraphic dissection of the Pre-Cambrian in Zholshoky, and these data will be applied throughout the Atassu-Moiynty watershed and other regions with Pre-Cambrian metamorphic outcrops.
