Thrust Fault Hanging Wall

A thrust or a reverse fault is a dipping fault whose hanging wall is translated up dip.

Thrust fault hanging wall.

Flat segments of thrust fault planes are known as flats and inclined sections of the thrust are known as ramps. The difference between the two faults is the angle of the fault. Diagram showing how one section of land slips over another in a thrust fault. 300 mbsf holes u1518b and u1518f penetrate the top of the fault zone.

Thrusts are commonly low angle faults. The angle of the fault plane in a reverse fault is greater than 45 degrees the hanging wall on one side of the fault moves upward and is usually visible on the surface of the earth. Reverse dip slip faults result from horizontal compressional forces caused by a shortening or contraction of earth s crust. According to mechanical models of.

The deformation style is localized and variable. Generally when the fault dips less than 45 it s called a thrust fault steeper faults are called reverse faults. Thrust faults typically form ramps flats and fault bend hanging wall and footwall folds. Other articles where thrust fault is discussed.

Thrust faults are reverse faults that dip less than 45. This is not however a hard and fast distinction. A thrust fault has the same sense of motion as a reverse fault but with the dip of the fault plane at less than 45. Thrust faults with a very low angle of dip.
