Exploration of Fault-Controlled Geothermal Systems: A Case Study in the Catalan Coastal Ranges (NE Spain)

Fracture field studies and the integration of geophysical data (MT, Gravity, and HVSR) show how localization of geothermal fluid systems is influenced by the lithology of the rock in the damage zone, but primarily enhanced by the presence of fault-related structural complexities as relay ramps.

About the event

This webinar will be preceeded by the AGA Annual General Meeting. The AGM is scheduled to start at 1:30 AWST followed by the webinar at 2:00 AWST.

Previous and new geological and geophysical datasets have provided the basis for an improved conceptual model that explains the localization of hot geothermal fluid systems at relatively shallow depths in the Catalan Coastal Ranges. Hot springs (60 - 70°C) are localized in specific areas along a major crustal fault, the Vallès-Penedès Fault, which delineates a horst-and-graben structure. Fracture field studies and the integration of geophysical data (MT, Gravity, and HVSR) have enabled imaging of how this localization is influenced by the lithology of the rock in the damage zone, but primarily enhanced by the presence of fault-related structural complexities as relay ramps.

Our presenter, Dr. Gemma Mitjanas is currently a research fellow at the Sustainable MInerals Institute (University of Queensland). Gemma earned her PhD in Geology at the Universitat de Barcelona. Her thesis, entitled "Geophysical and geological characterisation of fault-controlled geothermal systems," forms the basis for her presentation.
