anticline
/ˈantɪklʌɪn
/noun Geology
A ridge or fold of stratified rock in which the strata slope downwards from the crest. Compare with syncline.Large-scale geological structures including anticlines, synclines, thrusts and faults formed during the Caledonian Orogeny typically trend in a SW-NE direction....
- 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.
Derivatives
anticlinal
/ adjective ...- The expelled hydrothermal fluids were trapped in cap-rock situations inside anticlinal zones, such as the major lithological contrast between siliceous limestones and black shales at the flanks of the Arnsberg anticline.
- The later collapse of the mutual hanging walls of conjugate fault pairs has therefore created graben along the original anticlinal ridges that preserve the form of the anticlines but have destroyed the ridges.
- Strain differences between anticlinal and synclinal domains of concentric fold stacks require discontinuities between the two types of domain to maintain overall strain compatibility.
Origin
Mid 19th century: from anti- + Greek klinein 'lean', on the pattern of incline.
