The paper presents a petrochemical characteristics of plutons of different ages located in different zones and subzones of the Greater Caucasus Svaneti segment. In particular, petrochemical analysis of Svaneti segment of the Greater Caucasus showed that major magmatic phases of plutons are represented by different petrotype. Petrochemical studies s...

On the Cobalt-bearing granite pegmatites of the Rkvia Variscan pluton, Dzirula massif, Georgia

The Vakijvari ore field is formed in the central part of Paleogene the Achara-Trialeti fold-thrust belt, in the SW part of the Lesser Caucasus. The ore bearing pluton of the vakijvari ore field is considered as the largest igneous body of the region, which cuts through the Middle Eocenic volcano-sedimentary formations of mostly andesitic compositio...

On the Geoheritage of Georgia

The Eastern Caucasus Mountains in Georgia include products from extensive Miocene volcanic activity that are being unraveled by geological mapping supported by geochronology and geochemistry. This article presents new zircon U-Pb geochronology and whole rock geochemistry of the volcanic ash layers of the intermountain Neogene basin of the Eastern C...

This article presents new zircon U-Pb geochronology and whole rock geochemistry of the volcanic ash layers of the intermountain Neogene basin of the Eastern Caucasus. Our investigation in the region demonstrates that these ash layers, whose eruption source(s) have not been identified previously, have age and geochemical characteristics of the Kura...

Earth's globally significant geological heritage is recognized by UNESCO as a scientific, educational, environmental protection and economical areas. We believe that we have found one such site in the sedimentary cover of the Khrami massif. This pre-Jurassic crystalline massif (~500 km 2) is located in Georgia, within the Lesser Caucasus orogenic b...

From the Late Cretaceous to the Eocene, the Adjara-Trialeti fold-thrust belt with a length of more than 350 km is clearly expressed from the east of Tbilisi to the west to the Black Sea. It was interpreted as a back-arc rift that formed in the north of the Mesozoic island arc of the Lesser Caucasus (Gamkrelidze, 1974). Timing of the Adjara-Trialeti...

On Th Occurrences in Georgia

• Aspiring geoparks

Georgia is located in the central part of the Caucasus, which is the northern segment of the Eastern Mediterranean orogen system and extends over 1,200 km in a NW-SE direction between the Black and the Caspian Seas. In this study, our goal was to investigate the Th and U ore occurrences in the country. As a result of the research, we have identifie...

On Zircon U-Pb geochronology of the Vakijvari Pluton, Lesser Caucasus, Georgia

In Georgia, there is an additional advantage that the areas of high geoheritage value also coexist with areas of significant cultural importance and heritage. The medieval rocks-cut city of Vardzia is an excellent example of geoheritage supporting cultural heritage. It is located in Samtskhe-Javakheti volcanic highland (1300-2800 m a.s.l.).

The first part of the book discusses the energy potential of thorium and future prospects. Many researchers believe that thorium is the nuclear energy source that, without CO2 emissions, can fill the energy shortfall caused by the depletion of hydrocarbons in the future. Therefore almost all developed countries in the world are currently working on...

The Greater Caucasus belt is the northernmost expression of the Caucasus orogen and is linked to the southern margin of the Precambrian Scythian Platform. In the pre-Jurassic crystalline basement of this belt, a plagiogranite vein, exposed in the headwaters of the Enguri River, with elevated radiation (μSv/h range of ~1-3), has been discovered. The...

A granite vein with a thickness of ~2-3 m exposed in the headwaters of the Enguri River, with elevated radiation (μSv/h fluctuates in the range of ~1-3) has been studied in detail. It is located along the Main Thrust of the Greater Caucasus, in the Upper Paleozoic biotite-bearing migmatites of the Shkhara massif. The vein represents hydrothermally...

On Geological factors of formation of radon containing water, of the Tskaltubo resort, Georgia

In Georgia the Paleogene Adjara-Trialeti riftogenic belt (length 350 km, width 50-2 km) is dominantly composed of trachytic and trachytic-andesitic pyroclastic deposits, though plutonic rocks also play an important role in the structure. In this article, we report new data on the (LA-ICP-MS) U-Pb zircon geochronology and petrochemistry of the pluto...

Geological factors of formation of radon containing water, Tskaltubo resort, Georgia

Along the northern margin of the Arabia‐Eurasia collision zone in the western Greater Caucasus, the Main Caucasus Thrust (MCT) juxtaposes Paleozoic crystalline basement to the north against Mesozoic metasedimentary and volcaniclastic rocks to the south. The MCT is commonly assumed to be the trace of an active plate‐boundary scale structure that acc...

The geochemistry of the volcanic ash layers and the U-Pb geochronology of zircons in the Neogene intermontane basin of the Eastern Caucasus (Skhirtladze, 1964) has been studied. Investigation of the zircon U-Pb geochronology showed that the ash layers of the intermontane neogene basin of the Eastern Caucasus were deposited ~7.5 million years ago, i...

Zircons of the major ore-bearing plutons (Merisi, Namonastrali, Vakijvari, Zoti, Okros-Ghele and Rkviana) of the Adjara-Trialeti Paleogene folded zone of the Lesser Caucasus were dated by the U-Pb method using the Laser Ablation ICP-MS tool at the isotope laboratory of the Department of Earth Sciences at the National Taiwan University. The results...

Because of its unique properties thorium is considered as the main energy resource in the 3rd millennium. In Georgia are detected four Thorium ore occurrences: 1 - In the Sothern slope of the Greater Caucasus (Th con. 51 g/t - 3882 g/t), 2 - In the Dzirula massif (Th con. 117 g/t - 266 g/t), 3 - In Vakijvari ore field (Th con.185 g/t - 1600 g/t), 4...

The Caucasus defines the northern margin of the Arabia-Eurasia collision zone between the Black and Caspian Seas, within the Alpine Himalayan collision. Most orogen perpendicular convergence within this sector of the Arabia-Eurasia collision is absorbed within the Greater Caucasus, as indicated by seismicity, GPS velocity gradients and Neotectonic...
