The hyperbazite massives of the Sevan ophiolite zone have been formed during two stages: first stage – the crystallization of the under crustal and upper mantle peridotite magma with the formation of differentiated layered massive of stratiform intrusion type; second stage – the protrusive intrusion of the consolidated massives through the deep faults and its occurrence in the Mesozoic structures of the alpine circle regions. The layering and dark streak pattern structure of the dunite-harzburgite massives as a result of protrusive intrusion and intensive serpentinitation have not been preserved, and the broken and isolated chromite ore bodies are being scattered in the tectonised hyperbazites. The tectonic blocks of the hyperbazites and of massive ores, which had been broken and moved during the protrusive intrusion by the deep faults, are the relicts of the biggest bodies. Due to these processes the occurrence and manifestations of chromites are scarce in the protrusive massives of the Sevan ophiolite zone, and to expect those regularities of allocations practically is impossible.

The article is devoted to the application of deformation preventing measures for dams constructed out of swelling soils. Laboratory and fields tests have shown the relation between swelling pressure-compaction tension has a nonlinear character. On the basis of received dependence it is proposed to compensate the swelling pressure by the load calculated with the formula h = 0,3  σ_sw /ρ,  where ρ is a soil density,  σ_sw  is a swelling pressure.

At present, water supply of the eastern section of Dilijan City is implemented from the Spitakajur Stream waters, but they become turbid and unusable in the high water period. Water-geological conditions of the valley sections of the Spitakajur Stream middle flow are favorable for constructing waterside and infrabed water drainages, for intake of underground waters through them and for supplying with potable water the mentioned part of the City. Moreover, the volume of drainage waters, determined by the corresponding water-geological calculations, makes 20 L/s, which will completely satisfy drinking-household needs of the eastern section of Dilijan City (over 5000 capita).

The results of the tectonomagnetic studies of 5 profiles in the Ararat Seismic Polygon during 2013–2014 are given in the work. To allocate tectonomagnetic effects it is planned to carry out measuring twice a year, which will allow to reveal the local geomagnetic variations conditioned by the tectonic processes.

In the structure of tectonic magnetic field the component of its active dynamic part is found, which is called as dynamic tectonic magnetic field (DTM). The possible functional connection between the parameters of DTM and parameters of earthquake sources are investigated. As a result a constant quantity is obtained connecting these parameters.

The article presents the automation of creation of labeling of maps and plans via application modules. This method of generating labeling will give an opportunity to improve the quality of mapping, and upgrade it to a new level.

Golestan Region has a big potential for ecotourism development. Nowadays the usage of this potential is not on a sufficient level. For solving this problem there must be a strategy. The results of their research can serve as a framework for creating a strategy of ecotourism development. This strategy will be based on the usage of natural potential of the territory. At the same time, the strategy will include the complex usage of society capacity based on present and future interests.

The article examines the structural features of foreign economic relations of the Republic of Armenia, an attempt is made to identify their possible areas of development, causes of export reduction and import increasing in major commodity groups, are characterized and makes proposals to improve transport links with other countries of the region.
