Joint connectivity increases permeability of rocks that would otherwise be low in permeability. Natural fractures or joints form in response to tensile stress and are characterised by an absence of shear stress. Dominantly joints are systematic and pervasive they are affected by stress mechanisms which can change overtime leading to the formation of joint systems or networks. A field study of the natural fracture systems and patterns at the Cape Fold Belt and Karoo Basin transition, South Africa, was undertaken to compare and determine dominant natural fracture orientations. In the field...
