Papers and posters documenting the characteristics and origins of major examples of volcanic-hosted or volcanic-related deposits are particularly encouraged for this session. However, we also invite papers that address a wide range of topics about these deposits, including the genetic relation between volcanism, hydrothermal systems, and ore deposition; the setting and relation between high- and low-sulfidation systems; the influence of volcanic-edifice structures on solution flow and ore deposition; the duration of hydrothermal systems resulting from volcanic processes; the association of specific deposit types with geochemical types of volcanism and of both with tectonic setting; the role of meteoric and ocean waters in the origin of epithermal and massive sulfide deposits, respectively; the tie between modern geothermal systems and epithermal mineralization and, conversely, the relation of epithermal deposits to deeper, porphyry environments and deposits; and magmas as sources of metals and fluids. >>>> >>>>8.
