The Ulytau crystal-bearing region is located in the western part of the Kazakh folded country, distinguished by a significant complexity of the geological structure. The latter is due to the heterogeneity and varying degrees of dislocation of its constituent rocks.In connection with the manifestation of two stages of tectogenesis, two structural stages are distinguished in the folded base of the Ulytau zone.The purpose of this article is to study the features of the crystal content of the region.On the territory of the Ulytau district, 140 vein fields were identified, numbering up to 6,000 quartz veins, of which 1,700 with signs of crystallinity. Of the total number of crystal-bearing veins, 1100 were explored, located within 75 vein fields. Quartz veins, including crystal-bearing ones, are found in almost all rocks, including deposits of the Middle Carboniferous, which determine the upper age limit of the veins in the region.Productive (industrially -crystal-bearing) mineralization is manifested in the contours of the region more locally. Of the 110 identified fields and areas, industrial mineralization is associated with vein formations only 18 objects.
