Ichnofacies Interpretation of Trace Fossils Occurrences in the Paleocene-Lower Eocene Deposits of the Borjomi Canyon

The results of recently conducted integrated ichnological-sedimentological studies of the Paleocene-Lower Eocene deposits in the central part of the Achara-Trialeti Fold-and-Thrust Belt and inparticular within the Borjomi canyon are presented. Three sections containing trace fossils have beeninvestigated, i.e. the Papa, Ardagani 1 (Paleocene) and Ardagani 3 (Lower Eocene) sections. Theanalysis of trace fossil assemblages and sedimentological features helped to interpret depositionalenvironments of these sections. The Papa section represents a part of the outer deep-sea fan. TheArdagani-1 section belongs to the distal part of deep-sea turbiditic depositional system. The lowerand the upper part of the Ardagani-3 section represents the channel off-axis (intra-channel or thechannel-lobe transition) and a part of the deep-sea fan environment (such as the channel margin,depositional lobe or fan fringe), respectively. It has been assumed that Paleocene–Lower Eocenedeposits of the Borjomi canyon represent a deep-sea turbiditic depositional environment within theAchara-Trialeti rift basin.
