reverse fault
Học thuậtThân thiện
Definition
Noun: A reverse fault is a type of geological fault where the rock on the upper side of the fault plane appears to have moved upward relative to the rock on the lower side. This upward movement is caused by compressional forces in the Earth's crust that squeeze and shorten the rock layers.
Usage
The term is used in geology and earth sciences to describe and classify a specific kind of fault structure. - Geologists identified a reverse fault as the cause of the mountain's uplift. - The seismic activity was traced back to movement along a deep reverse fault.
Advanced Usage
- Thrust Fault: A reverse fault with a very low-angle fault plane (typically less than 30 degrees) is specifically called a thrust fault. Thrust faults can move older rock over younger rock.
- The Appalachian Mountains contain numerous thrust faults, a subset of reverse faults.
Variants and Related Words
- Thrust Fault (n): A low-angle reverse fault.
- Compression (n): The stress force that causes reverse faulting.
- Fault Scarp (n): A small step or offset on the ground surface where a fault intersects it, which can be created by a reverse fault.
Synonyms
- Thrust fault (specific type)
- Compressional fault
Antonyms
- Normal fault: A geological fault where the hanging wall has moved downward relative to the footwall, caused by extensional forces.
Noun
- a geological fault in which the upper side appears to have been pushed upward by compression
