1. A fold in which the limbs dip away from the hinge. After erosion, the oldest rocks are exposed in the central core of the fold. 2. A fold, generally convex upward, whose core contains stratigraphically older rocks.
A fold of rock layers that is convex upwards. An antonym of syncline.
A concave-downward fold, i.e. the limbs are depressed and the center raised.
The arch of a fold within strata. Bent rock, the curved over hump.
An upfold or arch in rock strata in which the beds or layers dip in opposite directions from the crest, permitting possible entrapment of oil and gas.
is a structure in which strata are folded so as to form an arch or dome.
A fold in rock that resembles an arch (generally convex upwards). The rocks in the core of an anticline are generally the oldest.
a fold in rocks in which the strata dip outward on both sides (limbs) away from the axis. A fold, which is concave downward, as in the shape of a barn roof.
A fold with an arch-like shape in which the limbs dip away from the hinge.
An arch of stratified rock in which the beds or layers bend downwards in opposite directions from the crest or axis of the fold.
Figure An anticline is a fold in rocks that brings rocks up from depth, forming an arch-like structure. The rocks in the center of an anticline are the older rocks.
A geological term describing a fold in the earth's surface with strata sloping downward on both sides from a common crest. Anticlines frequently have surface manifestations like hills, knobs, and ridges. At least 80 percent of the world's oil and gas has been found in anticlines.
A large upfold of strata, usually from 100 m to 300 km in width, whose limbs are lower than its center. (Compare Syncline.)
A convex upward rock fold in which strata have been bent into an arch; the strata on each side of the core of the arch are inclined in opposite directions away from the axis or crest; the core contains older rocks than does the perimeter of the structure.
rock layers folded in the shape of an arch. Anticlines sometimes trap oil and gas.
an arch (a fold convex upward), and a syncline is a trough (a fold convex downward)
an area of the earth's crust where folding has made a dome like shape in the once flat rock layers
an upfold or arch and where layers dip away from the axis (or hinge line)
an upfold, the rocks curving upwards in an arch, with the top being a crest and the sides being inclined limbs moving downward in opposite directions
an upward fold in the layers of rock, much like a domed arch in a building
a structure in which a) the oldest rock layers are located at the top of the structure, b) the rock layers dip away from the axis of the structure , c) rock layers are downwarped, d) all of the above are correct, e) none of these are correct
a structure in which the layers or strata are bent upward in the centre)
An upward fold or arch of rock strata.
An arched fold in which the rock layers dip away from the axis of the fold.
A fold of rock layers that convex upward. Oldest rocks located in the center of the anticline. Anticline
Landform. A place where layers of rock are bowed up in the middle to create a ridge. See also Syncline.
It is a fold in a rock where the strata protrudes upwards towards the fold. Each section of the rock reaches the highest point by the fold area.
Rock layers that have been bent so that they bow upwards or fold convex side up.
A subsurface geological structure in the form of an elongated dome. Historically this type formation has been found favorable to the accumulation of oil or gas.
A fold or fold system in the form of an arch
A geological structure where a cross section through sedimentary strata shows an up fold
a fold in layered rock, convex upward, with older rocks toward the core.
an upward fold in stratified rocks
A fold in layered rocks originating below the surface in the form of an elongated dome. Anticlines make excellent drilling prospects since any oil in the deposit will naturally rise to the highest point of the structure because oil has a lower specific gravity than water.
A downward-curving (convex) fold in rock that resembles an arch. The central part, being the most exposed to erosion, display the oldest section of rock. See syncline.
A folded structure in which the oldest rocks are exposed in the center when the structure is eroded. These are formed by compression, much like what happens when you push on a throw rug. (Image)
A fold of rock, generally convex upward, whose core contains the stratigraphically older rocks.
Anticline - A fold in bedded rock in which the beds dip (slant) away from one another.
Upward-arching fold of rock strata.
An upward fold in the crust. See syncline.
A fold where the rocks are bent convex upward.
Arched stratified rock structure with layers dipping downward in opposite directions from the crest.
A fold in the rock that resembles an arch; the fold is convex upward, and the oldest rocks are in the middle.
An arch or fold in layers of rock shaped like the crest of a wave.
A geological structure sometimes described as a dome or inverted saucer. Such a structure would be an anticline with "four way dip closure" which if covered by an impermeable layer of rock would make a potential oil or gas reservoir. Not all anticlines are this "perfect" shape.
an elongated fold in sedimentary rock that resembles an arch in which rock layers slope downwards in opposite directions from the central axis (the apex of the fold)
Rock strata are folded up into a ridge or hill-like structure, with the oldest rocks in the core.
synclinal Greek anti "against", klinein "to bend" The upward-tending part of saddle-shaped stone fold.
an arched, inverted-trough configuration of folded and stratified rock layers.
fold with an arch shape where geologic stratas dip in opposite direction from axis arch.
A subsurface geological structure in the form of a dome; that is, the formation rises to a rounded peak. In sedimentary rocks these are good prospects for drilling since, normally, oil & gas rises to the highest point in the structure. go back
An upwarped portion of a fold in the earth's crust.
An upfold of layered rocks in the form of an arch.
an upfold in rock strata producing an arch or dome structure. One of the most common hydrocarbon traps.
An arched fold, usually in the shape of an inverted U.
Arching rock fold that is closed at the top and open at bottom. Oldest formation occurs in the center of an anticline.
A fold of rock layers that is convex upward, or that had such an attitude at some stage of its development. Opposite of Syncline.
A fold in the strata of the Earth that is convex upward (shaped like an A) with the oldest rocks in the center. Antler Bony structure protruding from the forehead of members of the deer family.
In structural geology, an anticline is a fold that is convex up or to the youngest beds.
