Extraordinary diversity of physiographic conditions and complicated geological and tectonic structures are typical for volcanic structures that result in non-uniformly distribution of ground water resources and variety of its composition and mineralization. The thick volcanic blankets and streams covering the buried topography complicate ground water prospecting problems in volcanic regions in comparison with any other geologic regions. These circumstances complicate carrying out of hydrogeological (and engineering geological) works and it is necessary to apply other prospecting methods and first of all the geophysical ones. In the article have been discussed ground water resources evaluation and regularities of ground water run-off distribution on the pattern of Aragats volcanic upland. Inner and under lava water streams, buried watersheds have been distinguished. Compiled cartographic materials can be applied in ground water prospecting works in the areas of investigated river basins.

A network of carbon polygons has been established in Russia to study the emission and uptake of greenhouse gases in natural ecosystems and to develop technological solutions to control the fluxes of greenhouse gases in natural ecosystems with the aim of reducing their emission and increasing their uptake from the atmosphere. The pilot project is an important part of the low-carbon development strategy to decarbonize the Russian economy, adapt the economy to the global energy transition, reduce greenhouse gas emissions and achieve carbon neutrality in Russia by 2060. To achieve these goals, the pilot project uses an integrated approach that includes ground-based measurements of carbon balance and greenhouse gas fluxes, remote sensing data, and mathematical modeling methods. To provide observations of greenhouse gas fluxes, a wide range of experimental methods for direct and indirect measurements of greenhouse gas fluxes will be used. Direct field flux measurements include eddy covariance and chamber methods. Carbon polygons for monitoring greenhouse gas fluxes are planned to be distributed in the most representative natural terrestrial and aquatic ecosystems, allowing to assess the spatial and temporal variability of greenhouse gas emission and uptake. The territory of Armenia is a unique region in terms of diversity of climatic conditions and landscapes. The development of a system for monitoring greenhouse gas fluxes can serve as a guarantee of obtaining representative data on the emission and absorption of greenhouse gases by natural ecosystems, with the perspective of Armenia achieving carbon neutrality in the coming decades.

In Central Iran Eocene copper deposit occurs in volcanic arc setting hosted by Oligocene porphyrytic granite, which is intruded by a series of Miocene quartz-monozodiorite to granodiorite rocks. The intrusions were intruded into late cretaceous and Eocene sedimentary volcano-clastic and volcanic rocks. Major and accessory minerals with petrography data suggest that all copper bearing intrusions are I-type volcanic granitoids. Four hydrothermal alteration zones have been recognized in the porphyritic intrusions and surrounding rocks. This study identified the Cu-Mo mineralization at Ali-Abad area as a typical porphyritic Cu-Mo deposit, formed in an arc-related environment during Mid-Cenozoic era.

In the present paper in the territory of Armenia are distinguished the following basic tectonic units from the position of plate tectonics։ 1) the Armenian folded zone as northern segment of known Peri-Gondvanian Cimmerian continent, which had been detached from Gondwanaland in Permian-Triassic in the Neo-Tethys basin initiation and the North drift by the basin widening in Mesozoic time; 2) this moving was accompanied by Paleo-Tethys oceanic crust subduction under the Hercinian base of Tran Caucasian massif that led to formation of Virahayots-Artsakh (Somkhet-Artsakh) island arc construction in a course of Jurassic-Upper Cretaceous time; 3) at the collision of Cimmerian continent with Virahayots-Artsakh island arc construction of Eurasia South Margin the obduction of a shattered and melanged material of the oceanic crust (at Aptian-Upper Coniacian time) fell down to the both sides of the suture zone forming the Amasia-Sevan-Akera and Vedi ophiolite belts. As a result the territory of Armenia had been created since Upper Coniacian time. At the same time in the South the Neo-Tethyan basin starts to narrow owing to its oceanic crust northward subduction under the Iranian margin of the Cimmerian continent. It gave rise to the Urmia-Dokhtar magmatic arc a development on the southern active margin of Iran; 4) on relation to the Urmia-Dokhtar magmatic arc the territory of present Armenia became as back-arc position on distance of 300–350 km to the North of the arc. and since Lower-Middle Eocene back arc stretching and riftogene break out of the earth's crust has taken place installing the Sevan-Shirak rift and its en-echelon continuations of Vayots Dzor-Bargushat-Megri rift. They appeared to be link in the uniform Paleogene back arc en-echelon rift system of Black Sea–Adzhar-Trialet–Shirak–Megri–Talish–Southern Caspian Sea. The Orogenesis of Caucasus started since Oligocene time owing to collision of Arabia with Iran following to closure of the Zagros oceanic pool. This closure was reasoned by the Red Sea opening; 5) in a South-North compression circumstances between Arabia and Eurasia and Anatolia westward drift the latitude stretching forces were developed in Lesser Caucasus giving rise to near-meridian tearing breaks of crust, generating Upper-Pliocene Quaternary volcanic ranges, en-echelon connected with each-other by right lateral slide-slip faults forming the uniform system of Dzavakhet-Gegham-Artsakh volcanic ranges.

Geochemical anomalies of trace elements of both geogenic and technogenic origin occur in soils distributed in various ore fields. The distribution patterns of element concentration in soils are primarily influenced by the bedrock with different types of endogenic geochemical anomalies, and by the soil forming processes, which modify the basic geochemical composition and redistribute the content of metals within the soil profile. Alteration processes may lead to the release of potentially toxic elements, particularly heavy metals, into the environment.

Based on the data obtained from the previously conducted investigations and field tests, new invetigations have been conducted with the purpose to restore the trouble-free operation of Yerevan Underground and with the aim to drawdown the level of groundwater in the vicinity of some stations. Calculations by hydrogeological methods have shown that capasity of new drainage will be 445.5 L/s that will be discharged by means of gallery. Construction of the new drainage will contribute to steep drawdown of groundwater static level (it will be 3–5 m below the railroad track), particularly in the distance of 50–70 m from the existing drainage that will provide safe and long-lasting operation of the underground.

Mining of Sotk gold deposit is a potential threat to groundwater contamination of the Masrik basin and Lake Sevan. The article presents geologicalhydrogeological specifics of formation, transit and discharge of groundwater in the upper streams of the Sotk River. According to studies, the river's recharge from groundwater is related to drainage waters occurring in eluvial-deluvial sediments. Deeper ground water flow occurs under riverbed, in alluvial-proluvial sediments. Hydrogeological assessment has shown that the velocity and flow rate of groundwater flow are too small and do not contribute to the transport of contaminants through groundwater in considerable amounts.

Based on the critical analysis and reinterpretation of this material (mainly VEZ data), we compiled a new summery map at a scale of 1: 50 000 and sections for the regional water basin (paleorelief) of the entire catchment basin of Sevan Lake. Taking into account the fact that the regional water confinement is the main distributor of underground flow, the compiled paleorelief maps and sections provide objective information about the ways of passing the concentrated underground flow and propitious areas for their interception.
