Multiple geological and paleontological studies demonstrate that the Andean Cordilleras formed through distinct, punctuated tectonic phases across specific geological eras such as the Cretaceous, Paleogene, Eocene, and Miocene.
The claim is specific and empirical, dealing with the geological timing of the formation of the Andean Cordilleras. All retrieved papers that discuss the timing of Andean uplift consistently point to specific, episodic tectonic phases across various Cenozoic and Mesozoic eras (e.g., Late Cretaceous, Eocene, Miocene). Therefore, the verdict is SUPPORTED with zero contradicting papers.
