Geofluids (i.e. fluids located in the subsurface) are increasingly becoming of interest due to their significant role as natural resources. These fluids span a vast range of geological environments including groundwater drinking resources, shale gas and oil, deep/shallow geothermal resources and hydrothermal mineral resources. Despite being valuable resources, geofluids are both vulnerable to contamination or may themselves represent a potential source of contamination through externally-driven mechanisms, as in the case of shale gas extraction, CO2 leaking or land use for agriculture purposes. Ont he other hand geofluids themselves can be a source of natural contamination as in the geogenic contamination of groundwater resources containing elevated levels of trace elements including arsenic (As), chromium (Cr), iron (Fe), and uranium (U), amongst others. Strategic management of geofluids and protection of geological resources related to them is indispensable for the future sustainable development of these societal and economically important resources. The characterization of geofluids and their behaviour in natural or artificial (human-driven) circumstances requires a deep understanding of complex physical, geochemical and microbiological processes. They are influenced directly by geological setting, structural evolution, and fluid flow systems.

The aim of this session is to foster scientific discussion between those with interest in a range of geofluid systems to better understand the role which these fluids have as socio-environmental and economic resources. The session emphasises the importance of lithological & mineralogical characterizationof various systems including in aquifers for a range of geogenic contaminants in groundwater, specifically addressing the source pathways and mobilisation mechanisms. The session also welcomes work including fluid flow, hydrology, geochemistry, environmental tracers, microbial investigations and both numerical and statistical modelling in support of fluid and resource management.

The session is supported by the RGFC-IAH (‘Regional Groundwater Flow Commission’ of International Association of Hydrogeologists) and the EU H2020 ENeRAG (‘Excellency Network Building for Comprehensive Research and Assessment of Geofluids’) project.
