The article under consideration characterizes the lithological and stratigraphic position, the structure of the reservoir and the
facies-paleogeographic conditions for the formation of the Paleogene deposits of Uzbekistan. The study of the lithofacies
conditions for the formation of Paleogene deposits in sedimentary basins shows that the paleo-elevations of Central Asia in the
Late Paleocene-Early Eocene served as a natural boundary between two separated Syrdarya and Amu Darya sedimentary-
sedimentary basins. In the marine area, large paleo depressions of the Afghan-Tajik depression, the South Prearalie, Ustyurt and
a number of smaller depressions regulated facies changes in the composition of clay-carbonate silts. From uplifts to depressions,
the change of shallow marine carbonate-free facies to marine carbonates is shown.
