Severo-Paramushirskaya Hydrothermal-Magmatic System: Interaction of Modern Volcano Ebeko, Severo-Kurilsky Geothermal Deposit and Metallogenic Fluids

摘要

Case study of the Severo-Paramushirskaya (North-Paramushir) hydrothermal-magmatic system demonstrates paragenetic and genetic connection between the main components of this geological structure located in the northern part of the Vernadsky volcanic ridge: sub-intrusive bodies as heat sources and deforma-tional tensions in their endo- and exocontacts, ascending fluxes of metal-bearing fluids in deep-seated fault areas, thick sections of boiling solutions and therefore formed geochemical barriers and quartz-adularia metasomatites with ore mineralization, active Ebeko volcano and rock decompaction zone underneath.
