New Location of Trace Fossils in the Middle Eocene (lutetian) Volcanogenic-sedimentary Series of the Achara-trialeti Fold-and-thrust Belt (georgia): Preliminary Study Results

Year: 2024

Type: article

Abstract: Within the Borjomi canyon (the central part of the Achara-Trialeti Fold-and-Thrust Belt), one new section containing trace fossils – the Ardagani 4 section has been investigated. The examined for the first time trace fossil assemblage is closest to the Nereites ichnosubfacies of the Nereites ichnofacies, which is typical of mud- and silt-rich sediments in the distal part of deep-sea turbidite depositional systems (outer fan). The analysis of trace fossil assemblage and sedimentological features of the Ardagani 4 section suggests that the sediments of the lower part of the middle Eocene (Lutetian) of the Borjomi canyon reflect the environment of deep sea sedimentation by bottom currents. Within the Achara-Trialeti extentional basin, the existing Paleocene-lower Eocene turbidite sedimentary environment was preserved even at the beginning of the Middle Eocene.
