A type of fault where the rocks that lie above the fault are carried up with respect to those below. Consequently they thicken rock layers up - an expression of contractional deformation. Thrusts are one of the building blocks of mountain belts formed by continent-continent collision (e.g. Alps, Himalayas).

low angle reverse fault

A low-angle fault (or fracture) over which rocks are transported, with the direction of transportation up the dip of the fault. Thrusts form when the Earth's crust is placed under compression, such as in zones of continental collision.

geology: thrust (molten rock) into pre-existing rock

a low angle fault that forms during periods of mountain building

An overriding movement of one crustal unit over another, as in thrust faulting.
