Fluids and magmas rising from the mantle to the crust are the main agents of metals transport and deposition. Magmatic-hydrothermal ore deposits represent localized concentrations of economically valuable elements that have been enriched by orders of magnitude relative to the bulk crust. The genesis of such deposits involves the culmination of a variety of processes including the generation of metal and volatile-rich magmas, ore-fluid exsolution, and the efficient transport and precipitation of metals. Thus, geochemical signatures of fluids, melts, minerals and rock alteration are significant to identify rocks that are associated with mineral resources. Recently, field-based studies and high-pressure-temperature laboratory experiments continue to provide invaluable insights into these processes on a variety of scales, whereas the rapid development of computational capacity supports emerging disciplines such as computational chemistry calculations of metal-complex stabilities and numerical simulation of hydrothermal flow and magma chamber processes.
The aim of this special issue is to bring researchers together from these various disciplines to present recent progress made towards deciphering the inherent complexity of magmatic-hydrothermal ore formation. We expect contributions from multidisciplinary approaches that combine natural observations, laboratory experiments with fluid, minerals, rocks, melt inclusions, theoretical and thermodynamic models for reactive-transport simulations of ore-deposit formations.
