Anticline

Anticlines are upfolds (arched upwards) whereas synclines are downfolds (shallow- to steep-sided U shape). In a series of folds anticlines are always next to synclines that in turn are next to anticlines (unless disrupted by faulting).

anticline -- A fold of rock layers that is convex upwards. Antonym of syncline. archipelago -- n. A group of islands; an expanse of water with scattered islands.

anticline A fold that is convex upward, or that had such an attitude at some stage of its development. compare syncline . aphanitic A textural term meaning "fine-grained" that applies to igneous rocks.

The simplest types of folds include monoclines, anticlines, and synclines. A recumbent fold is a more complex type of fold where one limb of the fold passes the vertical. Faults form when the stress applied to rock does exceed its internal strength.
