• Resumen

  • Domeyko range is located in the Andean Precordillera in northern Chile. During Triassic the Pacific margin of Southwest Gondwana underwent a rifting that created several narrow and elongated basins oriented NW-SE. When subduction of Farallon plate beneath South American plate began, a back-arc basin developed in the area superimposed on the Triassic basin. Around early Cretaceous the extensional setting in the upper plate changed into a compresional one.

    During this stage Domeyko range was uplifted as a result of the inversion of previous extensional structures. The resulting thrust and folds structures involved both, the paleozoic basement and mesozoic cover.
