Scope Concentration, transportation and precipitation of valuable elements are closely associated with ore fluids in ore formation processes. It is important to understand the behavior of the elements to elucidate the genesis of ore deposits and to apply it to exploration. The ore formation processes are largely influenced by various fluids composed of magmatic fluids, metamorphic fluids, seawater, meteoric water and hydrothermal fluids derived from these fluids. Valuable elements are concentrated by dissolution, precipitation and alteration of minerals through fluid-rock interaction, physicochemical changes and mixing of fluids. This session widely covers various topics of case studies, experimental and theoretical studies, development of new analytical methods and others related to the ore formation processes.
Notes Each oral presentation is within 15 minutes including discussion except two invited talks.
