Definitions for "Thrust fault"
A low-angle fault (45 degrees or less) in which the hanging wall has moved upward in relation to the footwall. Thrust faults are caused by horizontal compression.
Fault with a dip of 45 degrees or less in which the hanging wall (upper block) appears to have moved upward relative to the footwall (lower block).
Thrust faults, also know as reverse faults are caused by compressional force. Like the plate experimnet on page two of this website. "Thrust, tectonic structure that is a low angle or reversr fault." ( Oxford , 1985)
