Antiklinaalin

Antiklinaalin is a geological term referring to an anticline, which is a fold in rock strata that is convex upwards or "arch-shaped". The limbs of an anticline dip away from the central axis. The oldest rocks are typically found at the core of an anticline, with progressively younger rocks towards the outer edges. This type of fold is formed by compressional forces in the Earth's crust, which cause the rock layers to buckle and bend.

Anticlines are significant features in structural geology and can be important in the formation of petroleum reservoirs. Traps can form where impermeable rock layers overlay porous, permeable rock layers that are folded into an anticline. Hydrocarbons can migrate upwards and become trapped in the crest of the anticline. In some cases, anticlines can also be associated with the formation of hills and mountains. Erosion can further shape anticlines, sometimes exposing the older rock layers at the core. The study of anticlines helps geologists understand the tectonic history and deformation of a region.
