Oldalfault

Oldalfault is a geological term referring to a type of fault where the displacement occurs along the plane of the Earth's surface. This is in contrast to dip-slip faults, where displacement occurs along the dip of the fault plane, or strike-slip faults, where displacement occurs along the strike of the fault plane. Oldalfaults are characterized by horizontal movement, with one side of the fault moving either up or down relative to the other. This type of faulting is commonly associated with extensional tectonic regimes, where the Earth's crust is being pulled apart. Oldalfaults can be further classified as normal faults, where the hanging wall moves down relative to the footwall, or reverse faults, where the hanging wall moves up relative to the footwall. These faults are significant in understanding the geological history of an area and can influence surface features such as valleys, ridges, and the distribution of earthquakes.
