Webinar – Fault-controlled geothermal systems in NE Spain, 23 May 2024

Webinar on “Exploration of Fault-Controlled Geothermal Systems: A Case Study in the Catalan Coastal Ranges (NE Spain)” by the Australian Geothermal Association

Registration is currently open for a webinar to be hosted by the Australian Geothermal Association on “Exploration of Fault-Controlled Geothermal Systems: A Case Study in the Catalan Coastal Ranges (NE Spain).” Attendance is free for all.

The details of the event are as follows:

• Date: 23 May 2024, 1:30 to 3:30 PM AWST
• Speaker: Dr. Gemma Mitjanas, Research Fellow at the Sustainable Minerals Institute, University of Queensland
• Registration: Register via this link

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.

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.

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.

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