English: In structural geology, a syncline is a fold with younger rock layers closer to the center of the structure, whereas an anticline is the inverse of a syncline. Illustrated are a folded sequence of rock layers, being old at the bottom and young at the top forming a syncline and two anticlines with corresponding axes (or here rather axial planes) marking their centers.
