Instantaneous rock transformations in the deep crust driven by reactive fluid flow
Original language description
Fluid–rock interactions are a fundamental component of geodynamic processes. They link mass and energy transfer with large-scale tectonic deformation and drive mineral deposit formation, carbon sequestration, and rheological changes of the lithosphere. Spatial evidence indicates that fluid–rock interactions operate on length scales ranging from the grain boundary to tectonic plates, but the timescales of regional fluid–rock interactions remain essentially unconstrained. Here we present observations from an exceptionally well-exposed fossil hydrothermal system from an ophiolite sequence in northern Norway that we use to inform a multi-element advective–diffusive–reactive transport model. We calculate the velocity of the fluid-driven reaction fronts and find that they can propagate at up to 10 cm per year, equivalent to the fastest tectonic plate motion and mid-ocean ridge spreading rates. Propagation through the low-permeability rocks of the mid-crust is facilitated by the transient, reaction-inducedpermeability increase. We conclude that large-scale fluid-mediated rock transformations in continental collision and subduction zones occur on timescales of tens of years when reactive fluids are present. We infer that natural carbon sequestration, ore deposit formation, and transient and long-term petrophysical changes of the crust proceed instantaneously, from a geological perspective.
