A dislocation of the strata of the vein.
A dislocation caused by a slipping of rock masses along a plane of facture; also, the dislocated structure resulting from such slipping.
To interrupt the continuity of (rock strata) by displacement along a plane of fracture; -- chiefly used in the p. p.; as, the coal beds are badly faulted.
A split or fracture between two blocks of rock in the Earth's crust that have slipped, slid or pushed against each other. An area where earthquakes commonly occur.
Approximately plane surface of fracture in a rock-body, caused by brittle failure, and along observable relative displacement has occurred between adjacent blocks.
A fracture in rock caused by stress.
A large crack in a layer of rock or the Earth's crust.
A displacement of subsurface layers of earth or rock that sometimes seals an oil-bearing formation by placing it next to a non-porous formation.
A slip-surface between two portions of the earth's surface that have moved relative to each other. A fault is a failure surface and is evidence of severe earth stresses.
A fracture or zone of fractures in a planet's crust, accompanied by displacement of the opposing sides.
A break in the Earth along which movement occurs. Sudden movement along a fault produces earthquakes. Slow movement produces aseismic creep.
is a fracture in a rock across which there has been displacement
a fracture in rock along which the adjacent rock surfaces are differentially displaced
a fracture in rock on which movement has taken place.
A discontinuity in rocks across which movement has occurred.
A fracture in rocks with relative displacement of two parts of the mass.
a break or fracture in the rock layers in the earth's crust. The rock layers are displaced or offset from one another on each side of the fracture.
A fracture in the Earth's crust where there has been displacement of one side relative to the other.
A break in the continuity of stratified rocks or even basement rocks. Faults are significant to oilmen because they can form traps for oil when the rock fractures, they can break oil reservoirs into noncommunicating sections, they help produce oil accumulations, and they form traps on their own.
A planar or gently curved fracture in the Earth's crust across which there has been relative displacement of the two blocks of rock parallel to the fracture.
It is a split in the earth crust where the two sides may shift in opposing directions, resulting in an earthquake.
A fracture or fracture zone along which there has been displacement of the two sides relative to one another.
A fracture of the earth's crust, where there has been movement between two blocks of crust. Where the edges of the bricks meet during the experiment on page one .
A discontinuity over which there has been displacement of rock strata. See Reverse Fault, Normal Fault and Strike-Slip Faults.
a fracture along which there has been differential movement of the oppo-site sides.
A fracture on which one body of rock slides past another.
Fracture in a mass of rock causing a relative shift in the separated segments.
great fractures between masses of rock at the earth's surface; a large crack or break in a series of rocks; where two plates slip past each other
A fracture in the earth's crust where the materials on one side have moved in relation to the materials on the other side. Faults may provide an easy path for magmatic intrusion. The sudden movement of material along either side of a fault causes earthquakes. Back
Fracture within the Earth along which displacement of one side with respect to the other has occurred.
Figure Faults are surfaces of breakage in rocks, along which some movement has taken place. The movement may be measured in millimeters or miles. Fault "planes" are often not actually flat surfaces, but may be curved or undulatory.
a break in the rock layers where movement has occurred.
A plane of fracture in a rock along which displacement has occurred.
sharp break in rock with a displacement of the block on one side with respect to the adjacent blocks
A crack in the earth's crust usually formed when two pieces of crust are moving past each other.
A fracture or fracture zone in rock along which movement has occurred.
fracture dividing a rock into two sections that have visibly moved relative to each other.
A break in the continuity of a body of rock, attended by movement along the break.
A fracture in rock across which there has been movement.
Fracture zone in rock along which there has been movement of the crust.
a major rock fracture exhibiting relative movement on vertical or horizontal planes.
A surface or zone of rock fracture along which there has been displacement, from a few centimeters to a few kilometers in scale.
a fracture in rocks caused by movement of the earth's crust (plate tectonics). Faults are usually caused by transverse plate movement.
surface of rock rupture along which has been differential movement.
A fracture in the Earth's crust accompanied by a displacement of one side of the fracture.
(geology) a crack in the earth's crust resulting from the displacement of one side with respect to the other; "they built it right over a geological fault"
a break (crack) in the Earth's interior that causes one side of the crust to be displaced to the other
a break (fracture) or crack in the rock along which movement has occurred
a break in rocks along which rocks have moved
a break in the earth's crust along which blocks of rock slip past one another
a break in the earth's crust along which movement can take place causing an earthquake
a break in the Earth's crust from movement
a break in the Earth's crust having relative movement of the two sides
a break in the earth's crust when movement occurs
a break in the layers of rock
a break in which the rock on one side slides or slips against the rock on the other side so that each side is displaced some distance from the other
a break through the solid rock beneath the soil along which movement and resulting displacement of the two sides occurs
a crack or rupture in the earth along which rocks on each
a deep crack in the Earth that marks the boundary of two plates
a discontinuous displacement of rocks along a surface
a fracture along which the blocks of outermost major layer of the earth, on either side have moved relative to one another parallel to the fracture
a fracture along which there is movement
a fracture between blocks of the earth's crust where either side moves relative to the other along a parallel plane to the fracture
a fracture having appreciable movement parallel to the plane of the fracture
a fracture in bedrock along which movement has taken place
a fracture in the crust along which one side has moved relative to the other side
a fracture in the earth along which movement has occurred
a fracture in the Earth's crust along which motion may occur
a fracture in the Earth's crust along which rocks on one side have been displaced in relation to rocks on the other side
