Anticline
Anticline
Anticline (pronounced: /ˈæntɪklaɪn/) is a term used in structural geology to describe a type of fold that is convex up and has its oldest beds at its core. The term anticline is derived from the Greek words 'anti' meaning 'against' and 'klinein' meaning 'to lean'.
Description
An Anticline is a fold that is arch-like in shape and has its oldest rocks along its core. This is in contrast to a Syncline, which is a fold with younger rocks closer to the center. Anticlines can be recognized and differentiated from antiforms by a sequence of rock layers that become progressively older toward the center of the fold.
Formation
Anticlines are usually formed by the compressional forces of tectonic plates that push layers of rock into folds. The process of anticline formation is known as Anticlinorium. This process can occur over a period of millions of years.
Types of Anticlines
There are several types of anticlines, including:
- Asymmetrical anticlines - One limb is steeper than the other.
- Symmetrical anticlines - Both limbs have the same angle.
- Overturned anticlines - One or both limbs are tilted beyond the vertical.
- Recumbent anticlines - The axial plane is nearly horizontal.
Related Terms
- Syncline - A fold with younger rocks closer to the center.
- Monocline - A step-like fold in rock strata.
- Anticlinorium - A large anticline on which minor folds are superimposed.
- Tectonic Plates - The two sub-layers of the earth's crust that move, float, and sometimes fracture.
