A plane of fracture, or divisional plane, of a rock transverse to the stratification.
A fracture in rock on which no movement has taken place.
fracture dividing a rock into two sections that have not visibly moved relative to each other. See also fault.
A plane or gently curving crack, separating two parts of once continuous rock which, however, have not moved relative to one another.
A rock fracture that does not show any movement. Like a crack in a window.
jointing a fracture or crack in rock with no displacement
A fracture or crack in rocks along which there has been no movement of the opposing sides (see also Fault).
A fracture of rock without displacement (displacement defines faulting). Jointing of bedrock by pressure release, thermal stress, frost action, and chemical weathering between glaciations allows rapid, effective erosion during glaciations.
In walling, the crack between two adjacent stones in a course.
a crack alon which no appreciable movement has occured
a fracture along which no movement has taken place
a fracture along which there has been no perceptible movement
a rock fracture along which displacement has not occurred
a fracture or parting in rock without any apparent displacement.
A naturally occurring plane of weakness or break in the rock, along which there has been no visible movement parallel to the plane.
is a discontinuity, fracture or parting in a rock, involving no displacement.
A fracture in rock layers along which no movement has occurred, usually formed by stresses placed on the rock, such as uplift and folding of rock layers.
joints in concrete can be tooled (while the concrete is still fresh), sawcut (after the concrete has hardened), or formed with wood, steel or other materials. The purpose of joints is to make the concrete crack where the joint has been installed (not to prevent cracks altogether). Another useful way to think of joints in residential concrete is to call them 'pre-planned cracks'.
A break of geological origin in the continuity of a body of rock occurring either singly, or more frequently in a set or system, but not attended by a visible movement parallel to the surface of the discontinuity.
A surface of fracture in a rock.
Fractures in rock along which no appreciable movement has occurred.
Crack or fracture in a rock or sediment.
A narrow crack in rock along which there has been no significant movement of either side. Joints commonly form in parallel sets.
A fracture in a rock along which there has been no movement, in contrast to a fault.
A crack (parting or fracture) formed in rock by movements normal to the cracks and without shear movements (by displacement) of the rock on either side of the crack.
Tiny hairline cracks formed in bedrock as stress relievers to a mountain building episode. Sometimes confused with faults, except joints never moved; the rock layer simply cracked. Since this mountain building episode occurred over a large area, joints in a relatively small area (such as our survey area) will likely be the same orientation.
Formed, sawed, or tooled groove in a concrete slab used to regulate the location of cracking ( control joint) or to allow expansion or movement of adjoining structures. In decorative concrete, joints can also double as delineating design elements in a pattern.
A fracture along which no appreciable movement has occurred.
a fracture in a mass of rocks, usually occurring in sets of parallel planes dividing the mass into blocks. [AHDOS
