This fault motion is caused by compressional forces and results in shortening. A reverse fault is called a thrust fault if the dip of the fault plane is small.

If the block on the far side of the fault moves to the left, as shown in this animation, the fault is called left-lateral. If the block on the far side moves to the right, the fault is called right-lateral. The fault motion of a strike-slip fault is caused by shearing forces. It is caused by a combination of shearing and tension or compressional forces. Nearly all faults will have some component of both dip-slip normal or reverse and strike-slip, so defining a fault as oblique requires both dip and strike components to be measurable and significant.

Both anticlines and synclines are the result of compressional stress. Part of a sequence of parallel rock is missing represented by the black line. They usually indicate that a long period of erosion occurred creating an eroded surface prior to deposition of the sediments several km of erosion necessary.
