In the article the structural condition of localization of golden, molibdenium and copper-molibdenium mineralization in the area are examined. The role of the disjunctive fractures, which are conjugated with Debacly fault, in the distribution of mineralization is elucidated. With the purpose of revealing new long-range territories a detailed geostructural analysis of 2-3 km width zone adjacent to Debacly fault is given.

Brief overview of Armenia's potential in supplementary ore and mineral resources, which could be extracted without significant capital investments from the industrial waists and mounds processing, sewerage treatment silt utilization as well as gold, titanium and other precious components' gravel deposits exploitation, reveals that prospective investors' attention should be focused on the mentioned above aspects. Thereupon, the works concerned with the Prikama's potential technogene deposits of sand methodological evaluation undertaken at Perm University have exclusive importance and their results are proposed below.

Initiating cryogenic ehodynamic system is one of the most progressive geomorphologic factors of relief formatting in landscape of Armenia and Artsakh highland zone (altitudes over 2 000 m). The article surveys climatic preconditions for developing of different cryogenic processes sub-types, their essence, nature and differences as well as microforms and sediments evolving alongside with them. Nivation is responsible for slips, Karrooids, scratched-up cones whereas cross- solifluxion causes slow movement of alluvial shingles and hillocks erecting. Polygonal gettings, stone rings, medallions originate from the ground freezing and thawing in periods of seasonal frosts. Cryogen processes carry negative impact on economic activities of man. This fact calls for detailed studies, wide range works for map drawing and drafting of nature protection program.

A number of essential peculiarities of intra-annual distribution of mineralization of river waters are analyzed in the paper. The results provide that the mineralization in river waters has a precise intra-annual distribution and directly relates to water discharge. The maximal value of mineralization and the minimal runoff of drought period manifest themselves simultaneously; while the minimal value of mineralization coincides with the maximal runoff in flood period.
