Thrust Fault Hanging Wall

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 fault hanging wall.

Flat segments of thrust fault planes are known as flats and inclined sections of the thrust are known as ramps. Reverse dip slip faults result from horizontal compressional forces caused by a shortening or contraction of earth s crust. 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. The hanging wall composed of extended thinned and brittle crustal material can be cut by numerous normal faults.

Thrusts are commonly low angle faults. Thrust faults typically form ramps flats and fault bend hanging wall and footwall folds. According to mechanical models of. The unloading of the footwall can lead to isostatic uplift and doming of the more ductile material beneath.

Generally when the fault dips less than 45 it s called a thrust fault steeper faults are called reverse faults. This is not however a hard and fast distinction. The lewis overthrust is a geologic thrust fault structure of the rocky mountains found within the bordering national parks of glacier in montana united states and waterton lakes in alberta canada. The difference between the two faults is the angle of the fault.

Thrust faults with a very low angle of dip. Diagram showing how one section of land slips over another in a thrust fault. Other articles where thrust fault is discussed. A thrust or a reverse fault is a dipping fault whose hanging wall is translated up dip.
