Anticlines (convex-up fold structures in rock layers) are often associated with compressional tectonic forces which cause layers to buckle and fold. Anticlines can also develop when extensional forces produce normal faults in a rock mass, provided the steepness (dip) of the normal faults ... A doubly-plunging anticline is a dome-shaped fold structure associated with a localized structural high within a given layer sequence, typically related to a distinct pattern of thrust faulting beneath the localized high. During erosion of the fold-thrust belt, the localized high point is exposed and cut by erosion before the rest of the ...
