http://www.engr.hk/T05/T%20RockS%20Failure.pdf WebbJoints are fractures in rock that show no slippage or offset along the fracture. Joints are usually planar features, so their orientation can be described as a strike and dip. They form from as a result of extensional stress acting on brittle rock.
