Crustal-Scale Duplexes Beneath the Eastern Rioni Foreland Basin in Western Georgia: A Case Study from Seismic Reflection Profile

Year: 2025

Type: article

Abstract: Our Understanding of the subsurface structure of foreland basins is based largely on seismic profiles. The seismic profile across the eastern Rioni foreland basin in western Georgia is crucial for identifying the deformation structural style. We used fault-related folding and thrust wedge theories to interpret these data. The seismic profile reflects that the dominant structural styles of the compressional structures are related to multiple detachments. We identiﬁed thin-skinned and basement-involved structures. The deep-level detachment in the basement develops the duplex. The formation of crustal-scale duplexes is related to the reactivation of pre-existing normal faults during compressive deformation. Based on the results obtained from the seismic profile, we assume that it represents the western continuation of the Dzirula massif.
