Modelling Seismically Induced Mesothermal Goldfields along the Deep-Rooted Cadillac-Larder Lake Fault, Abitibi, Canada

Figure 9

Schematic model and sections of the active Cadillac-Larder Lake Fault showing relationships between fault activation, seismicity, and fluid flow following failure on the Joannes Segment. (a) Seismic rupture along the active segment generates an increase in fault permeability and a drop in fluid pressure. (b) Upward fluid migration along damage zones. (c) Gold precipitation and iterative deposit formation over time. (d) Fault permeability closure, pervasive migration of metamorphic and/or magmatic fluids, and pressure build-up at the base of the seismogenic crust. (e) Doublet aftershock along secondary faults located in the main damage zone.
