Anticline - Wikipedia
In structural geology, an anticline is a type of fold that is an arch-like shape and has its oldest beds at its core, whereas a syncline is the inverse of an anticline. A typical anticline is convex up in which the hinge or crest is the location where the curvature is greatest, and the limbs are the sides of the fold that dip away from the hinge.

If the limbs dip away from the hinge, then the fold closes upward; we say the fold is an antiform. If the limbs dip towards the hinge, then the fold closes downward, and the fold is a synform.

Apr 24, 2024 · An upward fold is called an anticline (or, more accurately, an antiform if we don’t know if the beds have been overturned or not), while a downward fold is called a syncline, (or a synform if we don’t if the beds have been overturned). In many areas it’s common to find a series of antiforms and synforms (as in Figure 12.5), although some ...
Antiform: fold where limbs dip way from axial surface Monocline: gentle anticline-syncline pair with horizontal outer limbs Overturned syncline: one limb of syncline is overturned
5.12: Folds - Geosciences LibreTexts
Any fold whose form is convex upward is an antiform. Antiforms containing progressively younger rocks from their core outwards are anticlines. An anticline or antiform has a crest, which is the highest point on a given stratum along the top of the fold.

Dec 26, 2015 · An Antiform can be used to describe any fold that is convex up. It is the relative ages of the rock strata that separate anticlines from antiforms. The hinge of an anticline refers to the location where the curvature is greatest, also called the crest.

Antiform - an overview | ScienceDirect Topics
An antiform is a type of fold which closes upwards and its limbs dip away from the hinge, whereas a synform closes downwards and the limbs dip towards the hinge (Fig. 13.6A and B). You might find these chapters and articles relevant to this topic.

An upward fold is called an anticline (or, more accurately, an antiform if we don’t know if the beds have been overturned or not), while a downward fold is called a syncline, (or a synform if we don’t if the beds have been overturned).
PSGT8. Folds
This particular fold geometry is called an antiform. The opposite geometry, when the hinge zone is at the bottom (outlining a valley), is called a synform. The explanation for the modifiers “anti” and “syn” is that the limbs dip away from or toward the center of the fold, respectively.
