REMAINS OF NANNOPLANKTON DISTRIBUTED IN THE PALEOGENE DEPOSITS OF THE SURKHANDARYA DEPRESSION AND THEIR GEOLOGICAL SIGNIFICANCE

Abstract

This article analyzes the composition, stratigraphic distribution, and geological significance of nannoplankton remains distributed in the Paleogene deposits of the Surkhandarya depression. It has been demonstrated that nannoplankton identified in Paleocene marine deposits are of significant importance in determining the relative age of strata, performing stratigraphic correlations, and restoring the paleogeographic environment. Furthermore, based on nannoplankton complexes, the relationship between the marine conditions of the Surkhandarya depression during the Paleogene period and the Tethys paleobassine was evaluated.
