anticlines, plural;
  1. A ridge-shaped fold of stratified rock in which the strata slope downward from the crest

  1. (anticlinal) sloping downward away from a common crest
  2. In structural geology, an anticline is a fold that is convex up and has its oldest beds at its core. The term is not to be confused with antiform, which is a purely descriptive term for any fold that is convex up. Therefore if age relationships (i.e. ...
  3. (anticlinal) used to describe a type of cell division in a layer of cells that occurs perpendicular to the adjacent layer of cells; Describing a torsion angle between 90° and 150°
  4. (anticlinal) perpendicular to the surface. cf. periclinal.
  5. An arched fold, usually in the shape of an inverted U.
  6. 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.
  7. A fold of rock layers that is convex upwards. Antonym of syncline.
  8. 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.
  9. Landform. A place where layers of rock are bowed up in the middle to create a ridge. See also Syncline.
  10. A fold in rocks that curves upward in a convex way. Upward fold in rock layers that creates an arched or domelike uplift of sedimentary layers. See syncline.
  11. A upward(convex) folding of the rock strata.
  12. An arch of stratified rock in which the layers bend downward in opposite directions from the crest.
  13. a rock fold which is closed at the top; an upwarp in folded rock srata
  14. A convex fold in rock, the central part of which contains the oldest rocks.
  15. An upwarped portion of a fold in the earth's crust.
  16. A fold, generally convex upward, whose core contains the stratigraphically older rocks.
  17. Arching rock fold that is closed at the top and open at bottom. Oldest formation occurs in the center of an anticline.
  18. An upwardly convex fold with limbs that dip away from the axial position.
  19. An arched, convex upward fold in bedrock strata resulting from regional  compression. The oldest layers are found at the center, or axis, of the anticline. The two sides of the upfolded anticline, called limbs, dip, or tilt, downwards away from the axis. ...
  20. is a fold in a rock sequence that is (or that was at some stage of its development) concave downwards (convex upwards) – which is to say, all the strata [q.v.] slope downwards from a crest that may be circular, thus forming a dome, or they may be linear, thus forming a ridge [q.v. syncline].
  21. An arch or fold in the layers of rock shaped like the crest of a wave, as opposed to a syncline, which is similar to the trough of a wave.
  22. An arch of bedded or layered rock suggestive in form of an overturned canoe. (See fig. 16, p. 86; fig. 25, p. 117; P1. XIX, B, p. 103.) (See also Dome and Syncline.)
  23. An arch-like fold in stratified rocks.
  24. An upward fold or arch of rock strata
  25. An anticline is a fold in rocks that brings rocks up from depth, forming an arch-like structure. The rocks in the centre of an anticline are the older rocks.
