The character of distribution of chemical elements in ores, оrе concentrates, monomineral fractions, industrial tails and ore surrounding rocks of Thukhmanuk gold deposit have been studied. It is established, that during the process of extraction in structure of tails more than 0․5 g/t of gold and 1 g/t of silver remains. It is also established that ore surrounding rocks contain industrial gold, which can be characterised as additional sources of gold.

Gold-bearing of Sevan–Amassiya zone is more or less studied in its central part along the zone of large fault near latitude of strike. Rather perspective is the southern flank of tectonic zone, where in the contact parts of the terrigenous-carbonaceous facieses of the Upper Cretaceous with the volcanogenous-sedimentary rocks of the Eocene and Miocene thick zones with gold content up to 2.0–2.5 g/t are revealed. Practical interest is represented also to the scatterings of the area, where Sotk and Dilidjan deposits are located.

On the base of field geological-petrographycal and microscopic investigations in the Pkhrut-Lernadzor ore field the uranium bearing widespread formation of the secondary quartzite have been carried out.

In this work the analysis of geological structure, tectonics, morphology of the southern coast of the Caspian Sea for the purpose of microseismic division into districts and engineering-geological division into districts on susceptibility of territories to landslides and quicksand processes are resulted. Data are processed in the environment of GIS.

Karst as a dangerous engineering-geological process is especially disastrous for civil, industrial and hydrotechnical constructions. The article is discussing the results of engineering-geological, hydrogeological and geophysical complex investigations that were carried out in the northern part of Syria: in the territory of Ras Al Ayn City. Karst processes have been activated last few years in this territory mainly because of human activities. A number of target maps are drawn for case study area including zoning map of the karst risk, according to that map the city territory is divided into 3 parcels. Necessary engineering measures are proposed for ecological remediation of the studied area.

Main factors, contributing to coming of friable material to the South Caspian coastal zone, are examined. It is marked, that alongshore currents, prevailing in this area winds of northern directions, are of great significance in delivery of this material along the coast.

In the article the space-time, functional structures and mutual relations between day and week cycles of peoples' life activities have been analyzed. Some space-time rules and features of peoples' life activities functioning depending on size functional type and economic-geographical position of the communities in Armenia have been revealed.
