This article discusses the origin of ophiolits in the Sevan-Akerian zone from the point of view of classical theory of geosynclinal folded areas. The geological data confirm that over the Sevan-Akerian zone there is no evidence of the existence of oceanic crust rocks fragments, pulled over to the continent as a result of the closure of the ocean. Ophiolites are rocks of mantle origin, which have been crystallized and consolidated in the depths of subcrustal peridotitic melt, and subsequently intruded into deep faults in the form of a protrusion to the subsurface zone of the Earth's crust, bypassing oceanic situation. The term «ophiolite» should be used as the title of hyperbasites and not for the association of ultramafic rocks, gabbroids, volcanic and basaltic pillow lavas complex and deep-pelagic clays, as well as for siliceous (radiolaritic) sediments of the ocean floor.

The tectonic map shows the structure of Earth Crust of the territory of Republic of Armenia and the main stages of its development. It was worked out basing on the geological map, using geophysical and other data according to the principle "age of folding". The units of tectonic zoning are allocated on the map (folded regions of differrent ages, tectonic zones, subzones, orogenetic depressions, anticlinoriums, synclinoriums), local tectonic structures (anticlinals, synclinals, tectonic depressions, raisings, salt domes, etc.), volcanic centres and formations of different ages. Ruptures faults are dismembered into two groups: deep and intracrustal. The steps of evolution are showed as structure-formation complexes, subcomplexes and stages.

In the paper an attempt was made to separate the morphostructure of the Earth Crust sedimentary layer and by comparative analysis with the crystalline fundament's surface to explore the existing morphostructural connections between these layers on the territory of Armenian volcanic highland.

From the point of view of natural disasters risk, Armenia is a vulnerable country. Therefore, the study and qualitative assessment of natural disasters is important for sustainable development of the Republic. The impact of natural disasters is directly linked to the feature of economy and population of the Marzes. For this reason, the study and qualitative assessment of natural disasters on the level of districts and regions has an important strategic significance. Risk is the probability of natural disasters, the assessment of which is based on their potential danger and vulnerability. On the basis of their potential danger and vulnerability, the risk of natural disasters on the territory of Armenia has been estimated and composed the integrated risk map.

Displays of karst in calcareous rocks and forming of underground emptinesses in effusive rocks of Armenian highlands have been examined in the article. Broad spreading limestone-dolomite rocks in the mountains of the Minor Caucasus, Armenian Eastern Taurus and Inside Taurus, their considerable dislocation and intensive partition of ranges by deep valleys assist in developing of karst in the highland. In effusive rocks the formation of underground emptinesses are only partially. A lot of emptinesses are formed in them as a result of cooling of lava flow and loss of gas.

The interdependence of greening agriculture and sustainable development of society have been discussed in the article. The ideology of greening agriculture, and sustainable development based on the requirements of the solution of contemporary problems facing society, namely to maintain the standards of rational use of natural resources and to ensure a favorable future for population. For this purpose, a number of measures and technologies are suggested.

In the article the following stereotypes related to category Service have been drawn up and discussed: service as a third sector of labour division, service as an indicator of globalization, service society, service state, service human. All of these represent service as a system of services and type of activities based on theoreticalmethodological diversity. The object of serviceology is the human’s non-material needs and the effectiveness of human material needs satisfaction. The aspect to study serviceology is the educational scientific system which creates service human, service state and formation of state. The science of service tries to systematize all spheres of social life and makes possibilities for scientific solutions of actual diverse problems based on theory and methodology of effectiveness of human needs satisfaction.

The article proposes that cadastral mapping of underground spaces should be undertaken both manually and with instruments. It is preferable to use manual methods during cadastral registration work, while during the work for State Registration of Rights instruments should be used.

The article examines possible ways of developing agricultural tourism in Armenia. Analysing the experience of foreign countries, shows the importance of this sphere in the solution of social and territorial problems. The possible socioeconomic effect of developing of agricultural tourism in Armenia is evaluated.
