Evolution of fracture networks in shear zones: Insights from see-through experiments on biphenyl aggregates
Evolution of fracture porosity in mid-crustal shear zones can be simulated in in-situ experiments. Evolution of fracture networks was monitored during simple shearing of 2-mm-wide zones in wet and dry aggregates of polycrystalline biphenyl (C6H5C6H5) in a Urai-Means see-through deformation apparatus. At low effective confining pressure in wet samples, mixed brittle-viscous deformation occurred at all strain rates (5.6 x 10-4-5.8 x 10-6 s-1) at 94-97% of the absolute melting temperature. At the...[Show more]
