Rising demand of critical raw materials in response to the global energy transition is pushing scientific research for exploration and sustainable exploitation of crustal ore deposits from which these commodities are extracted. Mineral targeting in many countries is progressively shifting the focus of exploration and research from brownfield (i.e., already surveyed districts) to greenfield (unexplored) sites, thus deriving an improved and broadened multidisciplinary understanding of the geological factors that lead to the formation and preservation of a metallogenic province. Multiple geologic processes operating over time and space predispose sectors of the Earth’s crust to develop metallogenic provinces through short-lived and transient mineralizing episodes, which usually constitute the final outcome of a dynamic system of mass and energy fluxes. Understanding each component of these mineral systems and linking them together through a holistic conceptual framework provides key understanding for predicting the locations of hidden mineral camps. This session welcomes interdisciplinary contributions that describe the geological and geochemical processes involved in the selective transfer of critical raw materials and their storage in the Earth’s crust, with special emphasis (but not limited to) in the European domain. Relevant disciplines may include, but are not limited to, mineral systems science and economic geology, mineral exploration, mineral chemistry, geochemistry and isotope geology, numerical modeling, and geometallurgy. Contributions related to empirical and experimental studies on metal transport in magmas and hydrothermal fluids are also welcome.
