It's important to know a fault's type: normal, reverse or strike-slip. The type reflects the kind of forces that are acting on the fault. ... Normal faults form when the hanging wall drops down. The forces that create normal faults are pulling the sides apart, or extensional.

Normal faults can show diffeent geometries - and a few are shown here. In some situations the faults can become gently dipping at depth so that they have a spoon (or listric) shape. Other normal faults are found in batches, dipping in the same direction, with rotated fault blocks between.

The mylonitic foliation is cut by a steeper active normal fault, which is marked by prominent triangular facets on west-facing spurs. The ductile normal shearing deformation occurred during the interval 5-1 Ma.

Dip-slip faults include both ''normal'' and ''reverse''. A normal fault occurs when the crust is in extension. The hanging wall moves downwards relative to ... In the image below, you see a normal fault at left. A reverse fault is the same, except the hanging wall moves up instead of down. At right, you see a thrust fault.

A fault is a fracture in the Earth's crust where there has been measurable relative movement. A normal fault is the result of tensional stresses at or near the Earth's surface. The hanging wall moves down dip & the footwall moves updip. ... Normal-Fault-Block.jpg — JPEG image, 53Kb...
