Abstract
Annotation.The article considers the glauconite-bearing nature of the Paleogene deposits in the Syr Darya Depression.It summarizes the results of a comprehensive study of the material composition and formation conditions of glauconitic sandstones associated with the Paleogene strata of the depression.The patterns of spatial and stratigraphic distribution of productive glauconite horizons are described.Consequently, a sedimentation cycle of the Paleocene and Eocene periods is identified, reflecting the evolutionary trends of the Paleogene sedimentary basin in the study area.These findings provide a foundation for a new predictive strategy in the exploration of promising glauconite occurrences and deposits.
