Abstract

The shallow-marine sediments of the Middle Miocene (mainly the Konkian) of the Eastern Georgia (Eastern Paratethys, Kura basin) were investigated by cyclostratigraphy methods. Time series analysis (Lomb-Scargle and REDFIT periodograms, Gaussian filters) revealed statistically significant signal with 2,4–2,7 m wavelength corresponding most likely to the precession cycle. Based on statistical processes, a sedimentation rate of the studied sediments from 8,75 to 13,75 cm/kyr for different depositional setting was detected. We suggest that the studied Eastern Georgia Konkian sediments (Sartaganian and Veselyankian beds) accumulated during of at least 475–600 kyr. The Sartaganian (beds with most diverse marine fauna of the Konkian) can be correlated with interval of highest sea-level rise of TB 2,5 cycle.
