Definition of anticline in English:



  • A ridge or fold of stratified rock in which the strata slope downwards from the crest.

    Compare with syncline
    • ‘The displacement of the thrust sheet produces two anticlines and a syncline.’
    • ‘Its topography, represented by the alleged anticlines and synclines of Rosenkrantz, is instead an expression of the original sea-floor topography.’
    • ‘The field evidence includes the presence of several longitudinal extensional folds such as a rollover anticline and drag folds that are related to normal faults in the area.’
    • ‘It has been previously reported that because of extension of the outer arc of such anticlines, graben form above their crests.’
    • ‘Following the intrusion of basic dykes in the late Palacocene, the whole of the post-Zechstein succession was gently folded into a series of major synclines and anticlines.’
    • ‘In this case the folds found within the Miocene sediments have been interpreted as extensional folding in the form of the ramp anticlines and drag folds.’
    • ‘Tectonic movement locally folded and uplifted the Pabdeh Formation exposing it to erosion along the crests of anticlines before this unconformity was buried beneath the Asmari Limestone.’
    • ‘The Zagros Simply Folded Zone can be distinguished from the rest of the orogen by NW-SE-trending parallel folds and thrust-cored anticlines which verge to the SW in a 6-12 km thick cover sequence.’
    • ‘In this locality, the top 20 m of the Asmari Limestone exhibits palaeo-weathering along joints suggesting subaerial exposure of the Asmari near the crest of an anticline.’
    • ‘Bozkurt mainly provides a short, but incomplete, summary of previous work on field characteristics of extensional folds, including rollover anticlines.’
    • ‘From the maps presented in Figure 2, it is apparent that the well tested the crest of an anticline that formed during the Cenozoic.’
    • ‘Fold profiles of individual ramp anticlines above the thrusts suggest, using bed-length balancing, a minimum shortening of 10% as a result of folding.’
    • ‘Large-scale geological structures including anticlines, synclines, thrusts and faults formed during the Caledonian Orogeny typically trend in a SW-NE direction.’
    • ‘If this is true, then the succession had been folded into two long-wave length anticlines and intervening synclines with an amplitude of 35-40 m and several smaller folds.’
    • ‘In its hanging wall, however, a drag fold syncline and a rollover anticline developed.’
    • ‘This mechanical failure results in a topographic valley along the crest of the anticline.’
    • ‘Present along the surface exposures of the anticline are rocks dating from Upper Cretaceous to Paleocene age.’
    • ‘Folds associated with intraformational faults in the Tertiary mudstones of the southernmost North Sea show a similar asymmetry, with anticlines locally developing into diapiric structures.’
    • ‘It is possible that faulting along the crests of deep-seated anticlines provide the conduit for mobile muds to migrate through to the seafloor surface.’
    • ‘These fault-parallel footwall anticlines are best developed along fault segments 3 and 4, although there are also examples of fault-parallel folding in the footwall of fault segments 1 and 2.’


Mid 19th century: from anti- + Greek klinein lean, on the pattern of incline.
