 In recent years, hydrothermal-magmatic systems in modern volcanism areas have been in focus of researches as ore-generating structures. It is assumed that there is relation between geothermal and epithermal ore deposits. Hydrothermal deposits are diverse, being present in a wide range of geological settings and tectonic environments: some are closely associated with granitic intrusions, others form on the ocean floor and still others are in sedimentary basins. These components, including metals and their ligands, become concentrated in magmas in various ways from various sources, including subducted oceanic crust. Leaching of rocks also contributes components to the hydrothermal fluid-a process enhanced where acid magmatic vapors are absorbed by deeply circulating meteoric waters.
