Joint Spacing and Distribution in Deformation
Band Shear Zones
Tectonic joints localized within deformation
band shear zones on the Kaibab uplift in Utah, USA, show the same
spacing and distribution characteristics as joints controlled by
primary lithological mechanical stratigraphy, despite the fact that
deformation band shear zones are secondary structural features oblique
to primary sedimentary layers. The
spacing and distribution of joints that traverse deformation band shear
zones are important factors in the permeability and connectivity of
sandstone reservoirs compartmentalized by deformation band shear zones.
