What is an oblique-slip fault?
A fault that has a component of dip-slip and a component of strike-slip movement is termed an oblique-slip fault. Nearly all faults will have some component of both dip-slip and strike-slip, so a fault that is classified as oblique requires both dip and strike components to be significant and measurable.
How does an oblique-slip fault form?
This 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.
Which is an oblique type of fault?
Faults which move horizontally are known as strike-slip faults and are classified as either right-lateral or left-lateral. Faults which show both dip-slip and strike-slip motion are known as oblique-slip faults.
What does a strike-slip fault look like?
Strike-slip faults are vertical (or nearly vertical) fractures where the blocks have mostly moved horizontally. If the block opposite an observer looking across the fault moves to the right, the slip style is termed right lateral; if the block moves to the left, the motion is termed left lateral.
What is right lateral strike-slip?
What is a lateral fault?
strike-slip fault, also called transcurrent fault, wrench fault, or lateral fault, in geology, a fracture in the rocks of Earth’s crust in which the rock masses slip past one another parallel to the strike, the intersection of a rock surface with the surface or another horizontal plane.
What kind of fault line is in California?
continental transform fault
The San Andreas Fault is a continental transform fault that extends roughly 1,200 kilometers (750 mi) through California. It forms the tectonic boundary between the Pacific Plate and the North American Plate, and its motion is right-lateral strike-slip (horizontal).
What is vertical faulting?
What is left lateral strike-slip?
Left-lateral fault strike slip fault with low friction along fault contact. There is no deformation of the rock adjacent to contact. If the block opposite an observer looking across the fault moves to the left, the motion is termed left lateral. Example: the San Andreas Fault of California.
What is the difference between a left lateral and right lateral strike-slip fault?
What is a normal dip slip fault?
normal fault – a dip-slip fault in which the block above the fault has moved downward relative to the block below. This type of faulting occurs in response to extension and is often observed in the Western United States Basin and Range Province and along oceanic ridge systems.
What is an oblique reverse fault?

What is the definition of a strike slip fault?
strike-slip fault, also called transcurrent fault, wrench fault, or lateral fault, in geology, a fracture in the rocks of Earth ’s crust in which the rock masses slip past one another parallel to the strike, the intersection of a rock surface with the surface or another horizontal plane.
