types of faults geology
The type of motion along a fault depends on the type of fault. The main types of faults are described below. 1  Normal dip-slip fault. 2  Normal faults happen in areas where the rocks are pulling apart (tensile forces) so that the rocky crust of an area is able to take up more space. 3  The rock on one side of the fault is moved down relative to the rock on the other side of the fault.
Types of Thrust Faults â¢ Fault bend folds-fault forms before the fold; deformation restricted to the hanging wallâ¢ Fault propagation folds-fault forms along with the folding; deformation in both the hanging wall and foot wall. Example of a fault-bend fold thrust fault at the WVU Geology Field Camp.
