THRUST FAULT Meaning and
Definition
-
A thrust fault is a geological fault formed by the horizontal compression of Earth's crust, resulting in the displacement of rock layers in a essentially vertical direction. This type of fault occurs when forces acting on the crustal rocks cause one side to be pushed up and over the other side, leading to the overriding of older rock layers onto younger ones. It is most commonly associated with tectonic activity in convergent plate boundaries.
The characteristic feature of a thrust fault is the nearly-horizontal nature of the fault plane, inclined at a low angle to Earth's surface. The upthrown block, also known as the hanging wall, is situated above the downthrown block called the footwall. Thrust faults can span over vast distances, causing large-scale displacement of rock layers and sometimes resulting in the creation of mountain ranges or plateaus.
Thrust faults are important features in geology as they play a significant role in shaping the Earth's surface by uplifting older rocks and exposing them to erosion, leading to the formation of impressive landscapes. They also have implications for engineering and geologic hazards, as they can potentially cause earthquakes and landslides due to their large-scale movement and potential energy release.
In summary, a thrust fault is a type of geological fault formed by the horizontal compression of crustal rocks, resulting in the overriding of younger rock layers onto older ones. It is characterized by a nearly-horizontal fault plane inclined at a low angle, and it plays a crucial role in the geologic evolution of Earth's surface.

Etymology of THRUST FAULT
The word "thrust" is derived from the Old Norse word "þrysta" which means "to push". The term "fault" comes from the Old English word "feallan" which means "to fall".
The combination of these two words forms "thrust fault", a geological term that describes a type of fault in the Earth's crust where rock layers are pushed horizontally against each other, causing one rock mass to be pushed over the other.
