Terrestrial volcanism and related hydrothermal systems are widespread in subduction-collision related volcanic arcs and result in the formation of important deposits of metallic and industrial minerals. Papers in this session will discuss these mineral deposits, as well as updated models for their formation, highlighting the importance of mineralogy in understanding geochemical and volcanological processes. Review of the present status of knowledge about formation of mineral deposits in terrestrial volcanic-hydrothermal systems will be provided by invited keynote lecturers. Detailed aspects of mineralogy, geochemistry, origin and transportation of metals, fluid-rock interaction, volcanological processes and relationships between local and regional scale evolution of volcanism and formation of mineral deposits will be discussed during the session.

Several post-conference field trip associated with the topic of the session will provide insight into mineralogy, petrology and volcanology of porphyry to epithermal copper and gold deposits, as well as industrial mineral deposits (clays, zeolites etc.) that are characteristic of terrestrial volcanic-hydrothermal systems well preserved in the Carpathians of Central Europe.

The session expects broad interests from mineralogists, geochemists and economic geologists. The geochemical aspects are relevant to participants interested in mineral formation, metal and fluid transport in hydrothermal systems and/or mineralogy of fluid/rock interaction. Combined with the volcanological aspects, recent understandings about local and regional scale processes will highlight practical/mineral exploration importance results of academic studies.
