FEATURES OF FORMATION AND SEARCH FOR GROUNDWATER IN VOLCANIC REGIONS (BASED ON COMPREHENSIVE STUDIES OF THE DRAINAGE BASINS OF MOUNT ARAGATS MASSIF, RA)

Numerous targeted studies have been conducted in many regions of volcanism due to the exploitation of the Earth's natural heat, the use of thermal springs, and the search for mineral resources. Scientific and practical tasks are solved, in particular, during exploration and prospecting for water to meet water supply and irrigation needs. Increasing the efficiency of surveys and the reliability of the results obtained requires the improvement of search methods and techniques. Solving problems in volcanic regions is complicated by the fact that the sought-after marker horizons are mainly hidden under a thick cover of lava flows and sheets. This circumstance particularly necessitates the use of a combination of various research methods during water exploration and prospecting.
