چکیده انگلیسی


- Calculations estimate flow through a jointed cataclastic deformation band.
- Flow rate can equal or exceed discharge through highly porous sandstone.
- Jointed cataclastic deformation bands do not restrict fluid flow.

Cataclastic deformation bands in porous sandstones present a potentially significant barrier or baffle to fluid flow because the bands form in complex networks of laterally extensive, tabular zones with permeability up to several orders of magnitude less than that of the sandstone host rock. Previous work suggests that in some geologic settings cataclastic deformation bands become systematically jointed in the subsurface. Calculations presented here demonstrate that under most realistic circumstances, volumetric flow rate across a jointed deformation band can equal or exceed discharge through an equivalent volume of host sandstone. Results indicate that jointed deformation bands are not significant barriers or baffles to fluid movement.
