Andean orogeny
Videos
The Andean orogeny is an ongoing process of orogeny that began in the Early Jurassic and is responsible for the rise of the Andes mountains. The orogeny is driven by a reactivation of a long-lived sub
Paleogeography of the Late Cretaceous South America. Areas subject to the Andean orogeny are shown in light grey while the stable cratons are shown as grey squares. The sedimentary formations of Los Alamitos and La Colonia that formed in the Late Cretaceous are indicated.
The seaward tilting of the sedimentary strata of Salto del Fraile Formation in Peru was caused by the Andean orogeny.
Situated between Lake Titicaca and the Cordillera Real in Bolivia, the Altiplano forms an extensive intermontane plateau whose uplift is one of the most striking features of the Andean orogeny.
Tilted strata of the Yacoraite Formation at Serranía de Hornocal in northernmost Argentina. The Andean orogeny caused the tilting of these originally horizontal strata.
