Information - TS1.6 The architecture, evolution and mechanical behaviour of fault systems in strike-slip and extensional settings
The session will encompass a range of topics centred around brittle faults in strike slip and extensional environments in order to advance our understanding of fault geometry, mechanics and evolution. A better understanding of these processes has profound implications for at least two broad areas of great societal significance:
1) Brittle faults are key controls of crustal permeability patterns during hydrocarbon migration, economic mineralization, aquifer development, disposal of radioactive waste and exploitation of geothermal energy. This is because faults are able to form sealing barriers to fluid migration, or serve as cross-stratal conduits for large volumes of fluid flow.
2) In areas of active crustal deformation brittle faults represent a source of seismic hazard that can be better quantified on the grounds of a comprehensive knowledge on fault dimensions, degree of interaction and fault-slip behaviour.
We invite contributions from field geology, seismic exploration, petroleum geology, seismology and reservoir modelling that contribute to a better quantification of fault zone architecture and processes at all scales in the brittle Earth’s crust.
