Anticline

An anticline , anticline , anticlinory or geological saddle is an arching of stratified rocks created by folding . In a narrow sense, the term is limited to bulges in which the original top / bottom relationship of the layer sequence is preserved. The general case of bulging without taking age sequence into account is called antiform . An anticline is created by compressing part of the earth's crust by means of lateral pressure. Large and small folds can overlap, so that the rock of a large geological fold usually appears undulating.
The geometric structure that is inverse to the anticline is called the syncline . On the earth's surface , which has been leveled by erosion , the oldest rocks lie near an anticline in the center and are surrounded by younger rocks.
