An anticlinorium is a large-scale anticline or a series of anticlinal folds that together form a complex, mountainous structure. These structures are common in regions that have undergone significant compressional tectonic forces, such as during the formation of mountain ranges. The study of anticlinoria is important in understanding the large-scale tectonic evolution of orogenic belts.
