The paper presents a comprehensive analysis of weak anomalies identified by various geophysical methods: using statistical methods and identifying their relationships with mineralization. The data, obtained from the studies of the T'Tjujur–Chambarak copper ore deposit on the methods of magnetic prospecting, natural electric field and vertical electrical sounding, are considered in the form of a group of random variables that obey the laws of normal and lognormal rules. On the results of statistical analysis, those areas of the survey are considered as anomalies, where points are regularly accumulated, for which the detected values are most impossible for a given distribution. At the same site, the presence of weak anomalies identified by various methods makes it possible to speak with confidence about the existence of ore bodies that cause these anomalies.

The article deals with the selection of geophysical methods associated with advancing the effectiveness of landslide processes, both with the description of spatial boundaries and mapping, and with the purpose of monitoring the dynamics of slip in time and forecasting.

The article describes the experience of using the geographical information system (GIS) for recognizing lineaments and ring structures that are weakly developed on the surface. The selection of the latter is crucial for the reasonable selection of ore taxon of different orders – ore knots, fields and deposits, which contributes to the efficiency of geological exploration work. The results of the research allowed us to present the structural features of the studied territory in a new way.

Based on the results of the research, the processes of groundwater resources pollution and depletion were revealed in the Ararat Valley. To avoid the mentioned processes, it is necessary not only to prohibit digging new boreholes in the Ararat Artesian Basin, but also urgently define the limits of the current groundwater abstraction. At present the digging of new boreholes are prohibited in the Ararat Valley. In addition, currently such activities as well ceasing, conservation and regulation of the operational wells by valves take place in the Ararat Valley. In order to achieve the positive result, mentioned activities should be performed in continuous manner.

In the article tectonic-geomorphological analyses were done with the aim of tectonic activity observation of blocks of the territory of Armenia. By analyses the most active and passive block units were highlighted. The relations between blocks tectonic activity and seismicity were observed, in the result of which general regularities of confinement of seismic events (with different strength) to certain interblock tectonic situations were revealed. On the bases of block tectonic activity differences the qualitative assessment of seismotectonic potential of fault different segments was done.

The current state of the Debed Rriver basin system has been analyzed and assessed, anthropogenic pressures on water resources have been discussed, the super objectives of the sphere have been analyzed and clarified mechanisms for effective use and protection of water resources have been proposed.

The correlation analysis between rural settlements population number and their absolute height, cultivable land area, spatial and time distances from the nearest service centre have been given in the article. The revelation of regional differences and features of rural settlement in frontier areas has been highlighted through the analysis of transport-geographical location of settlements.

The research of RA frontier, mountainous and high mountainous areas settlement pattern, revelation and solution of current problems is one of the ways of effective use of territorial and human potential of such regions. The concepts of geographical survey of RA frontier, mountainous and high mountainous areas settlement pattern are discussed in the article. The issues of settledness, population and settlements distribution symmetry and diffusion, settlement pattern territorial structure and dynamics, population number of settlements, demographical situation and current problems, also the interaction issues of settlement territorial structure and administrative-territorial division are highlighted in the article.

At the Faculty of Geology and Geography of the International Conference dedicated to the 100th anniversary of YSU.

A report on the work of the 5th International Conference "Mudflows: Disasters, Risks, Forecast, Protection" is presented.
