[SE] There are numerous thrust faults in the Rocky Mountains, and a well-known example is the McConnell Thrust, along which a sequence of sedimentary rocks about 800 m thick has been pushed for about 40 km from west to east (Figure 12.16). thrust fault: translation. Also known as reverse fault; reverse slip fault; thrust slip fault. Faults that are truncated downward against the Lewis thrust are inferred to have originally soled into a structurally lower thrust fault, in which case displacement must have shifted out of sequence from this original fault (here named the Lewis I thrust) to the present-day, structurally higher surface (the Lewis II thrust) at some time during the evolution of the Lewis thrust system. noun.

A type of fault, with movement of the Earths crust, in which a lower stratigraphic layer is pushed up and over a younger one as a result of compression forces. They move deeper rocks over shallower ones and accommodate crustal shortening. Wikipedia. As a result, a series of overlying thrust sheets is produced that follow their associated fault detachments. Transcript 3. The fault plane is where the action is. In addition, there is a westward dipping basal detachment that extends into the Cordilleran metamorphic core at mid-crustal levels. a a variety of a normal fault b a response to horizontal tensional stress c one in which the hanging wall moves down d a strike-slip fault e a variety of reverse fault This arcuate shape, imposed primarily by differential advance of the thrust -front from zero at tip points to maximum somewhere along the fault trace, is the basis for the .

Thrust and Reverse faults form by horizontal compressive stresses and so cause shortening of the crust. Pay attention to how the bedding planes move relative to each other notice how they begin to double up in both forms of reverse fault, while in a normal fault sections begin to disappear in the middle, being lost from hypothetical drill core entirely. Thrust faults, particularly those involved in thin-skinned style of deformation, have a so-called ramp-flat geometry. Thrust fault in the Qilian Shan, China.The older (left, blue and red) thrust over the younger (right, brown). Where the fault plane is sloping, as with normal and reverse faults, the upper side is the hanging wall and the lower side is the footwall. The strain is released by seismic slip along thrust faults within the Longmen Shan thrust fault zone and exhibited by great relief. Start studying Thrust Fault Systems.
