Normal Fault Diagram Slickensides. Where the fault plane is sloping as with normal and reverse faults the upper side is the hanging wall and the lower side is the footwall. Diagrams of stress trajectories and draw on the expected orientations of faults.
Due to irregularities in the fault plane exposed slickenfibres typically have a stepped appearance that can be used to determine the sense of movement ac. Diagrams of stress trajectories and draw on the expected orientations of faults. Normal dip slip faults are produced by vertical compression as earth s crust lengthens.
However there definitely are steep thrust faults.
This also predicts that normal faults ought to be steep and thrusts are shallow. This surface is normally striated in the direction of movement. In this position the fault blocks represent unfaulted or unmoved crust. Horst graben up to structural geology topic list.
