a narrow island ridge (an archipelago of small, usually rocky islands), corresponding to the arch section of a developing geanticlinal uplift. Cordilleras appear in the early state of the development of a geosyncline. They occur most extensively during the final stage of development of the geosyncline, disappearing as independent formations when uplifts begin to predominate, that is, during the state of orogeny. The term was introduced by the Swiss geologist E. Argand in 1916 and was first used in Russian geological studies by V. P. Rengarten in 1926.
