An area between two parallel faults that is lower than that on the other side of the faults.
Helpful?           0
A downthrown block between two normal faults of parallel strike but converging dips; hence a tensional feature.
Helpful?           0
trench like depression representing the surface of a crustal block dropped down between two opposed blocks
Helpful?           0
An elongate crustal block that is relatively depressed (downdropped) between two fault systems.
Helpful?           0
An elongated, downthrown block bounded by two steeply dipping normal faults. Produced in an area of crustal extension.
Helpful?           0
An elongate fault block that has been lowered in relation to the blocks on either side.
Helpful?           0
A downfaulted block of rock.
Helpful?           0
A depression formed by the dropping of a central block between two parallel inward-sloping normal faults. Graben indicate a zone of horizontal tension.
Helpful?           0
a down-faulted block of rock
Helpful?           0

Helpful?           0
a block of the Earth's crust that has dropped down relative to another piece (the horst)
Helpful?           0
a depression formed when block of the earth's surface moves downward between two faults
Helpful?           0
a down dropped and typically linear depression
Helpful?           0
an elongated depression that is bounded by normal faults
Helpful?           0
a depressed segment of the earth's crust bounded on at least two sides by faults.
Helpful?           0
A crustal block of rock generally long and narrow, that has dropped down along boundary faults relative to the adjacent rocks.
Helpful?           0
A block of rock that lies between two faults and has moved downward to form a depression between the two adjacent fault blocks. See also horst.
Helpful?           0
a block bounded by faults that has been downthrown relative to rocks on either side, forming a basin
Helpful?           0
An elongate block of rock down-dropped along roughly parallel faults.
Helpful?           0

Helpful?           0
A graben (or rift) is a valley between two faults.
Helpful?           0
a long, depressed crustal block that is bounded by faults
Helpful?           0
"Literally a grave, but used as a technical term by geologists to indicate a depression between parallel fault lines." (p 430)
Helpful?           0
a down-dropped block of the earth's crust resulting from extension, or pulling, of the crust. See also horst.
Helpful?           0
regional scale collapse trench, normal faults bounded.
Helpful?           0
a topographic valley, created by motions along faults at the edges of the valley (see Fig. 2a).
Helpful?           0

Helpful?           0
An elongated, relatively depressed crustal unit or block that is bounded by faults on its sides.
Helpful?           0
