In this scientific article, besides our research, a number of research and production enterprises in the Republic of Armenia, as well as materials of hydrogeological and geophysical studies have been used for various types of exploration of the Lake Sevan catchment basin. For this purpose, we have used electrical, basically vertical electrical sounding (VES) field data as a control method and materials to drill wells cuts the measured points. According to electro-sounding materials, we have investigated the strength of the waterproof layer of the area and, taking into account the absolute altitudes of the measured points, according to local watersheds, we have identified the regions of the corresponding direction, which we called the map of the paleo-hydro-zoning of the the Lake Sevan catchment basin.

The article considers the results of complex geophysical studies performed in the south of the republic due to the planned construction of the Meghri HPP. As a result, the necessary data for hydro-geological, geo-geological conditions of the site and possible tectonic faults were obtained, which will be used for the HPP construction.

In this work the history of development of instrumental observations done in the Caucasus before and after the devastating earthquake of Spitak of 1988 is given. The representative registrations are calculated that is very important for the study of seismic activity of the territory. In this article is indicated, where can be taken the data of the catalogue of the main parameters of the earthquakes of the Caucasus. The development of the observation net will enable to graduate the whole period and receive identical data for the region and particularly for the territory of RA.

In the previous study an analytical database of geological obsidian samples was obtained within the method of portable X-ray fluorescence (pXRF). In this paper 292 obsidian samples from three settlements belonging to the Kura-Araxes culture were studied. Using the pXRF method, the chemical composition of these samples was compared with the results of geological ones to identify their sources. This will give a chance to understand the origin of the raw material.

The earlier described "ringing tufas", that were regarded as normal pyroclastic tufas, are explosive breccias of andesite composition, epigenetic with regard to the enclosing strata. The explosive breccias of the Ore Region of Alaverdi generate both embedded interlayer formations and shapless dyke-resembling bodies of the paleogenic age, but not as stratum unit in the column of Oxford.

In the article on the basis of analysis and generalization of the research outcomes of the author and different other researchers, some geographical features and development regularities of rural areas and settlements distribution in mountainous countries are worked out.

The RA frontier settlements are primarily villages and among the other factors, their perspective development depends on the population number of settlements and age structure of population as well. Based on the analysis and generalization of factual and statistical data, the regional differences of the rural population age structure of the RA frontier areas are given in the article. The current problems have been revealed.

In the article, the geo-ecological situation caused by the use of nature of the territory of the Republic of Armenia is presented, analyzed, interpreted and evaluated from a geographical point of view, based on the methodological framework of territorial synergistic effect and the concept of ecological-economic balance of the territory. The cause-and-effect relationships of the geo-ecological situation and its territorial picture are also presented.

Advertising is an integral part of modern life. Essential to the effectiveness of the advertising is the color. The color is kind of a control program. The right choice of colors enables you to control the ratio of advertising to the consumer product. The main task of color in advertising is providing comfort.

Mountainous territories are potential tourism areas, which are conditioned by natural resources and conditions, human intervention and existing infrastructures. As a result of investigation in the Republic of Armenia it is suggested to developed eco- and agrotourism, cognitive, scientific, business, amateur and other forms of tourism, for which a serious and effective state approach is needed.

The problems of compiling the physico-geological model (PGM) of the investigated territory were considered for predetermining the possible complex of geophysical methods for solving tasks. Аs an example, the PGM of Meghri HPP (Armenia) projected hydrotechnical tunnel territory is considered.
