Anticlinorium

ANTICLINORIUM (from the Greek words "anti" (opposite), "klino" (incline), and "yros" (mountain, hill) * EN: anticlinorium; DE: Antiklinorium; FR: anticlinorium; ES: anticlinorio; RU: антиклинорий) is the large and complicately built complex of the folds of the layers of the Earth's crust, which usually emerges within the geosynclines.

It is characterized by the general rise of the surface, which is tangent to the vaults of the anticlines (of the mirror of folding) within the central part. It has many hundreds of kilometres in length, and tens of kilometres in width. Especially large anticlinorium is named meganticlinorium. There emerge onto the surface of anticlinorium more ancient and usually more metamorphosed rocks, than within the synclinoria, which are adjacent to them. The axial planes of the folds are often situated like a fan (with the rollover to the side of the adjacent synclinoria). There often develop on the limbs of anticlinorium the zones of the thrust disturbances. There are often confined to anticlinoria the outcrops of the large intrusive bodies (granites, and others). The example of anticlinorium is the Greater Caucasus.
