  • adjective Botany Of or relating to the plane of a cell division perpendicular to the surface of a plant organ.

from The Century Dictionary.

  • Inclining in opposite directions from a central axis: applied to stratified rocks when they incline or dip from a central unstratified mass, or when in consequence of crust-movements they have been folded or pressed together so that they dip each way from a central plane, which indicates the line parallel to which the folding has taken place: opposed to synclinal. Occasionally anticlinic and anticlinical.
  • noun In geology, an anticlinal line or axis, or an anticlinal fold; an anticlinal arrangement of strata: opposed to synclinal.
  • They may be inert
  • active (albuminigenous), or
  • cotyloid. Vesque.

Sorry, no etymologies found.


  • The so-called anticlinal structures, which have been found by experience to be so favorable to the accumulation of oil, are by no means symmetrical in shape or uniform in size.

    The Economic Aspect of Geology

  • England is disturbed by two great swells, forming what are called anticlinal axes, one of which divides the London from the Hampshire basin, while the other passes through the Isle of Wight, both throwing the strata down at violent inclination towards the north, as if the subterranean disturbing force had WAVED forward in that direction.

    Vestiges of the Natural History of Creation

  • The Yakima Folds ecoregion consists of unforested anticlinal ridges composed of layer upon layer of basalt many thousands of feet thick.

    Ecoregions of Oregon (EPA)

  • The plateau is locally punctuated by a limestone valley and a few anticlinal ridges.

    Ecoregions of Delaware, Maryland, Pennsylvania, Virginia, and West Virginia (EPA)

  • The principal Formation is orientated in an east-west direction, and comprises both a long anticlinal and synclinal, the latter elevated over some degrees.

    Miguasha Provincial Park, Canada

  • The ridge trended north-west, as most others did in this extensive basin; and this direction being nearly parallel to that of the coast ranges further northward, seemed to afford additional reason for expecting to find anticlinal and synclinal lines, and, consequently, rivers, much in the same direction.

    Journal of an Expedition into the Interior of Tropical Australia

  • In 1814 the English geologist Thomas Webster published a description of the geology of the Isle of Wight in which he showed that the chalk strata forming the central range of hills in the island were vertical or very steeply inclined and that they formed one side of an anticlinal fold, the opposite side of which, he discovered on the south shore of the Isle of Wight.

    Dictionary of the History of Ideas

  • We found our way in here, "he jerked his head toward his amateur tunnel," by accident, in Thompson's time, one day when the stope happened to be empty; and we burrowed on to what looked like the anticlinal, before we heard the stope shift coming and had to slide out.

    The La Chance Mine Mystery

  • The more scientific generally select a spot either on the anticlinal or synclinal axis of the formation, giving preference to the former position.

    Burroughs' Encyclopaedia of Astounding Facts and Useful Information, 1889

  • There is ample proof throughout the country of alterations of level within recent geologic periods; and there have even been compressions, resulting in a relative rise of the ground, over the crests of anticlinal folds, within historic record.
