| Abstract | The purpose of this work is creating the complex geological-geochemical model of evolution of a typical long-living (beginning from thousands and up to hundreds of thousands years and even more) hydrothermal-magmatic ore-generating system of the Kuril-Kamchatka insular arch. This model is considered as the basis for development of estimation and safety use of the richest thermal, water and mineral resources of recent and ancient volcanism areas. Specific examples were used to ground existence and show formation stages of hydrothermal-magmatic ore-generating systems of the area of ocean-continent transition. The hydrothermal-magmatic system geological structure is studied and thermo-controlling zones as well as ore-controlling ones are distinguished. The structure of areas of near-surface and abyssal solution intensive mixing and water boiling as well as geochemical barrier zones is shown. New conceptual models of hydrothermal-magmatic ore-generating systems are offered. The work has been done with a financial support of the Russian Fund of Fundamental Research (project 06-05-64689a), Presidium of Far East Division RAS (projects 06-III-À-08-332 and 06-III-Â-08-371) and Russian Association of Geothermal Energy Society. |
