Abstract

Understanding the behavior of fluids in seismically active faults and their chemical-physical (dis)equilibrium with the host rock is important to understand the role of fluids upon seismicity and their possible potential for forecasting earthquakes. The small number of case studies where seismic and geochemical data are available and the lack of accessibility to fault zones at seismogenic depth for recent earthquakes limit our understanding of fluid circulation and its relationship to seismicity. The study of fault-fluid relationships in exhumed faults can broaden the number of case histories and improve our understanding of the role of fluids in the seismic cycle in different tectonic settings. Here we use new geochemical and thermal data and a review of published studies from the Apennines fold-and-thrust belt (Italy) to provide a model of fluid circulation during the seismic cycle related to either the local orogenic compressional or post-orogenic extensional tectonics. We also suggest a workflow based upo
