Deformation of Permian strata overlying a zone of salt dissolution and collapse in the Texas Panhandle

Brittle deformation of strata overlying salt dissolution zones has been identified in Caprock Canyons State Park, Texas Panhandle. The geometry and distribution of the structures indicate that systematic regional joints that predated dissolution collapse influenced salt dissolution. Collapse has resulted in a sequence of deformations including normal faulting, reverse faulting, folding, and veining. The sequence of structural events suggests horizontal extension prior to major collapse. It is proposed that dissolution fronts are complex features with re-entrants controlled by the locations of joint zones.
