What kind of underground activity occurs in thrust fault?
A thrust fault is a type of fault, or break in the Earth’s crust across which there has been relative movement, in which rocks of lower stratigraphic position are pushed up and over higher strata. Reverse faults Thrust faults typically have low dip angles. A high-angle thrust fault is called a reverse fault. The difference between a thrust fault and a reverse fault is in their influence. A reverse fault occurs primarily across lithological units whereas a thrust usually occurs within or at a low angle to lithological units. It is often hard to recognize thrusts because their deformation and dislocation can be difficult to detect when they occur within the same rocks without appreciable offset of lithological contacts. If the angle of the fault plane is low (generally less than 20 degrees from the horizontal) and the displacement of the overlying block is large (often in the kilometer range) the fault is called an overthrust. Erosion can remove part of the overlying block, creating a fe
