Abstract
Sarmatian sediments in Kakheti are oil-bearing and have been explored through deep oil wells. Analysis of these wells revealed changes in foraminifera complexes within the sediments. The Konkian sediments transition into Sarmatian sediments, which contain specific foraminifera indicative of their era. The lower Sarmatian sediments overlay Upper Konkian layers and contain transitional foraminifera species, linking Konkian and Sarmatian faunas. These complexes are similar to those found in Moldova, Crimea, Northern Caucasus, and Western Georgia. Middle Sarmatian sediments are divided into three parts, while lower Sarmatian sediments are divided into two, showing a clear succession of foraminifera over time. Upper Sarmatian sediments mainly contain Ostracoda and lack foraminifera. This stratigraphic study in Kakheti aligns with findings in other Eastern Paratethys regions.
