A monocline is a simple fold structure that consists of a bend in otherwise horizontal rock layers. More commonly found are anticlines and synclines. An anticline fold is convex up and one in which the layered strata are inclined down and away from the center of the fold (if you drew a line across it, the anticline would resemble a capital ...Extensive folding is represented by a repeated pattern of anticlines and synclines. Two anticlines are always separated by a syncline, and two synclines are always separated by an anticline. One side of the fold is called the limb; a side‐by‐side syncline and anticline share a limb. Frequently, an anticline or syncline can be identified ... The structure resembles a box-like anticline with a fold wavelength of ∼6–7 km and a fold amplitude of ∼0.7 km measured along the PS-top surface. Fold limbs pass laterally to two wide synclines.
