We report new observations in the eastern Black Sea-Caucasus region that allow reconstructing evolution of Neotethys Cretaceous. At time, oceanic plate was subducting northward below continental Eurasia plate. Based on analysis obducted ophiolites crop out throughout Lesser Caucasus and East Anatolides, we show a spreading center (AESA basin) existed within Neotethys, between Middle Jurassic Early Later, carried into subduction with argue opened slab window allowed asthenospheric material to...
The Great Caucasus is a northwest-southeast-directed mountain range more than 1100 km long, located between the Black Sea and Caspian Sea. It represents an intracontinental tectonic system resulting from Late Cenozoic structural inversion of Palaeozoic-Mesozoic-Early back-arc basin (Dizi basin) in response to convergence Africa-Arabian Eurasian lithospheric plates. bounded south by Transcaucasian massif, palaeo-island-arc, north Scythian platform. fold-and-thrust belt characterized complete,...
In this study, we document the structural architecture of frontal part active Greater Caucasus orogen based on interpretation seismic profile in western Georgia. It is a unique example to understand far-field intracontinental ongoing mountain building within Arabia–Eurasia collision system. The external zone orogen, known as Dzirula massif and Imereti Uplift Zone, developed during late Alpine period response convergence between Arabian Eurasian plates. Massif (DM) Zone (IUZ) break...
Our Understanding of the subsurface structure foreland basins is based largely on seismic profiles. The profile across eastern Rioni basin in western Georgia crucial for identifying deformation structural style. We used fault-related folding and thrust wedge theories to interpret these data. reflects that dominant styles compressional structures are related multiple detachments. identified thin-skinned basement-involved structures. deep-level detachment basement develops duplex. formation...
Abstract The Kura foreland fold–thrust belt is located in the northern part of active collisional Lesser Caucasus orogenic associated with Arabia–Eurasia convergence. This best example mountain-building processes late Alpine time. Seismic reflection profiles show that eastern an thin-skinned and represented by fault-bend folds, fault-propagation folds duplexes. Analysis growth strata seismic oil well data from documents evolution deformation has been continuing during last c. 14–15 myr...
Intraplate structural deformation is diagnostic of tectonic stress regime changes linked to plate interactions and can result from superposed events whose single contributions are hardly distinguishable. In this paper, we present a set integrated thermochronologic inverse models along 140 km-long transect across the central Greater Caucasus adjacent Adjara-Trialeti fold-and-thrust belt Georgia, two intraplate orogens produced by inversion parallel continental rift zones located on Eurasian...
Nine Mesozoic and Cenozoic palaeogeographic maps are presented to illustrate the petroleum prospectivity of South Caucasus from a fresh perspective as part wider region. Previously, elements systems – reservoir, source sealing lithologies, timing their formation have mostly been examined within individual sub‐basins or licence blocks, regional understanding has limited. Emphasis is placed here on onshore Georgia Azerbaijan; well‐known Pliocene Productive Series eastern Azerbaijan southern...
In the broader Caucasus region, multiple extrusive volcanic units are present within Jurassic, Cretaceous, Eocene and Miocene sedimentary successions. Partial reworking of material from various provenance areas into Eocene, Oligocene reservoir is commonly observed in Eastern Black Sea Rioni, Kartli Kura Basins onshore Georgia. Reservoir quality has general been negatively affected by rock fragments which may have undergone complex diagenetic alteration. However, despite concerns regarding...
Our study is focused on the structural geometry of western part Kura foreland fold-and-thrust belt (KFFTB) disposed in central Caucasus.Structural architecture Georgian KFFTB has been interpreted using seismic reflection profile.Building structures basin was formed by Greater Caucasus basement wedge propagation along detachment horizons within cover-generating thin-skinned represented Neogene shallow marine and thick continental sediments.Based style deformation, two seismicstructural...
2D seismic reflection profiles revealed the presence of a triangle zone at frontal part western Kura foreland fold-and-thrust belt pro-wedge Greater Caucasus. To understand geometry, interpretations should be substantiated by forward kinematic modeling, supported analog experiments. This study presents new structural model for region integrating field observations, well data, and data. East-West directed along-strike variation thrust is observed on interpreted which affected fold geometry....
The Rioni foreland fold-and-thrust belt is part of the Greater Caucasus pro-wedge and one most important examples collision-driven far-field deformation Arabia-Eurasia convergence zone. Here we show structural style based on seismic reflection profiles regional balanced cross-section. main within represented by a set fault-propagation folds, duplexes, triangle cross-section shows that folds above upper detachment level can develop piggyback break-back thrust sequences. Formation fault-bend...
The Greater Caucasus orogen is a typical active double wedge that accommodates the crustal shortening due to far-field effects of collision between Arabian and Eurasian plates.

The Rioni foreland basin system is located between the Lesser Caucasus (LC) and Greater (GC) orogens. Deformation of double flexural was controlled by action two opposing orogenic fronts, LC retro-wedge to south GC pro-wedge north (Alania et al., 2022). fold-and-thrust belt (RFFTB) part pro-wedge.  Here we show deformation structural style RFFTB based on seismic reflection profiles serial cross-sections. On basis cross-sections, 3-D models. 2-3D models that a thin-skinned main...
Collision and subsequent convergence of Arabia Eurasian plates during the late Alpine time caused extensive intracontinental deformation in Caucasus region (e.g., Cavazza et al., 2023). Inversion back-arc basins, exhumation, crustal thickening took place far-field zone, forming two orogens, leading to a between Lesser (LC) Greater (GC). Continuous LC GC incremental Kura foreland basin (Alania Our study area is located within LC-GC zone western represented by lenticular-shaped compressional...
