The Riffelberg-Garten Unit (RGU) is a tectono-stratigraphic unit that forms part of the Zermatt-Saas Zone (ZSZ) ophiolites of the Western Alps, which experienced peak metamorphism under eclogite facies conditions during alpine subduction. It is often referred to as a "chaotic" complex, since it is a mélange composed of a mixture of metasediments an...

Understanding how the brittle deformation pattern at the surface relates to active seismogenic sources at depth is one key element for accurate Seismic Hazard Assessment procedures based on deterministic inputs. Establishing a relationship between surface faulting and deep sources can, however, be very challenging, especially in areas where seismog...

A multi-proxy thermal maturity dataset constrains the thermal evolution of the sedimentary successions within the eastern Adjara-Trialeti, western Kura and central Greater Caucasus inverted basins in Georgia. Located in the hinterland of the Arabia-Eurasia collision zone, those three basins differ in age, subsidence mechanism and degree of structur...

Structural interference along the boundaries of adjacent tectonic domains generates complex subsidence and exhumation patterns. In this paper we study a key segment of the convergence zone between the interfering south-verging Greater Caucasus and north-verging Lesser Caucasus retro-wedge. The study area comprises the along-strike transition betwee...

This paper presents a new structural model for the frontal part of the eastern Achara-Trialeti fold-and-thrust belt based on the interpretation of a seismic reflection profile across the retro-wedge of the Lesser Caucasus orogen. The structural details from the interpreted seismic reflection profile provide new data on the deep structure of the fro...

We present a brand new multi-proxy dataset of thermal maturity indicators, which derive from the application of several analytical techniques on surface and subsurface sedimentary successions. The study area spans from the Greater Caucasus to the Adjara-Trialeti fold-and-thrust belt (FTB), comprising the intervening western Kura Basin, in Georgia,...

Thermal history reconstructions can help to better characterise the geological history of areas that experienced a polyphase tectonic evolution. The integration of published stratigraphic/structural data with new and pre- existing data on thermal maturity (clay mineralogy, Raman spectroscopy, vitrinite reflectance, and pyrolysis) of both surface an...

The 350 km-long Adjara-Trialeti fold-and-thrust belt of southwestern Georgia is the result of the structural inversion of a continental back-arc basin developed in the Paleogene on the upper (Eurasian) plate of the northward subducting northern branch of the Neotethys. Low-temperature thermochronological data [fission- track and (U-Th)/He analyses...
