Abstract

The middle Miocene (mainly the Konkian) shallow marine sediments of Eastern Georgia (Eastern Paratethys, Kura basin) have been studied for the first time with cyclostratigraphy methods. Time series analysis (Lomb-Scargle and REDFIT periodograms, Gaussian filter) revealed a statistically significant signal with a 2.4–2.7-m wavelength, which most likely corresponds to the precession cycle. It was established that the sedimentation rate of the studied sediments varied from 8.75 to 13.75 cm/kyr in dependence on different sedimentation environments. It is assumed that the studied Eastern Georgia Konkian deposits (Sartaganian and Veselyankian beds) accumulated during at least 475–600 kyr. The Sartaganian Beds can be correlated with interval of the highest sea-level rise at the TB 2.5 cycle.

佐治亚州东部（库拉盆地东部Paratethys）康克沉积岩的正地层

摘要

首次使用旋回地层学方法研究了佐治亚州东部中东部的中新世（主要是康克人）浅海沉积物（Eastern Paratethys，库拉盆地）。时间序列分析（Lomb-Scargle和REDFIT周期图，高斯滤波器）显示了一个具有统计意义的，波长为2.4-2.7-m的信号，最有可能与进动周期相对应。已经确定，所研究的沉积物的沉积速率根据不同的沉积环境而在8.75至13.75 cm / kyr之间变化。假定已研究的东乔治亚格鲁吉亚康克期沉积物（萨塔格期和维瑟利扬基岩床）至少在475-600年间积累。萨塔格尼亚河床可以与TB 2.5周期最高海平面上升的时间间隔相关。
