“…The Central Cordillera has an extensive Mesozoic-Cenozoic magmatic record characterized by a series of plutonic bodies considered to be Late Jurassic to Late Cretaceous in age (Aspden et al, 1987;Villagómez et al, 2011). These rocks intrude the Permian-Triassic and older metamorphic basement (Vinasco et al, 2006;Restrepo et al, 2011;Villagómez et al, 2011;Martens et al, 2014). The Mesozoic magmatic record is related to a volcanic arc formed by the subduction of the Farallon plate beneath the NW margin of South America (Aspden et al, 1987;Villagómez et al, 2011;Cochrane et al, 2014a).…”

“…During the Permian-Triassic, the Central Cordillera and the Cordillera Real of Colombia and Ecuador experienced the last phases of the agglomeration of Pangea and the beginning of its breakup, which is reflected in bimodal S-type and gabbroic syntectonic magmatism (Vinasco et al, 2006;Restrepo et al, 2011;Cochrane et al, 2014b;Martens et al, 2014). Following this event, there was an apparent magmatic and tectonic quiescence, reflected in the formation of significant carbonate platforms until the Late Triassic to Early Jurassic (Cediel et al, 2003;Ramos, 2009), until subduction resumed in the Early Jurassic (Ramos, 2009;Vásquez et al, 2010).…”

“…Las edades Triásicas que predominan en circones detríticos de la muestra analizada para la Formación Guineales pueden representar un aporte de las rocas metamórficas asociadas a la Cordillera Central (Paragneis migmatítico de la Palmas, Neis augen de las Palmas (Martens et al, 2014), Neis de Palmitas (Vinasco et al, 2006) La edad más reciente que arroja los circones de la muestra estudiada es del Mioceno (10,5 Ma) y concuerda con el intervalo de edades que se presenta para el Arco del Botón entre 9 y 12 Ma . Teniendo en cuenta su posición tectónica y su afinidad en los análisis multi-método desarrollados en este estudio, puede significar aporte de esta unidad en la cuenca de la Formación Guineales.…”
