Geanticline

 

(geology), a local upwarping of the earth’s crust within the confines of a geosynclinal system. Geanticlines are belts up to several dozen km wide and as much as several hundred km long, and they often exist over several geological periods. In their final stages of development, geosynclines become the nuclei of folded mountain systems. The island arc of the Kuriles is an example of a modern geanticline, and the Uraltau Ridge in the axial part of the Urals is an example of an ancient geanticline.
