An anticline which plunges at both ends is termed a doubly plunging anticline, and may be formed from multiple deformations, or superposition of two sets of folds, or be related to the geometry of the underlying detachment fault and the varying amount of displacement along the surface of that detachment fault. A structure that plunges in all directions to form a circular or elongate structure is a dome. Although they can occur singly, they most frequently occur as joint sets and systems. Keep in mind that erosion has stripped away the upper parts of these structures so that map view reveals the interior of these structures. In terms of geologic structures, the up folds are called anticlines and the down folds are called synclines. A structure that plunges in all directions to form a circular or elongate structure is a dome. anticline. A basin is similar to a syncline, but instead of an axis it has a single point at the center. An axis is an imaginary line connecting the hinges in the different strata in a two-dimensional cross-section through the anticline.
