Short summary
We documented the role of fluids in the initial embrittlement of the Svecofennian basement and subsequent strain localization and fault evolution at the brittle–ductile transition zone. We studied the fault rocks of a deeply exhumed fault system characterized by mixed brittle–ductile deformation. Results from fluid inclusions, mineral chemistry, and geothermometry of synkinematic minerals document the ingress of distinct fluid batches and fluid pressure oscillations.
We documented the role of fluids in the initial embrittlement of the Svecofennian basement and...
