Geochronology, geochemistry and tectonic evolution of the Western and Central cordilleras of Colombia

Popis výsledku v původním jazyce

We present the first regional U?Pb zircon ages for intrusive and metamorphic rocks of the autochthonous Tahami Terrane, Early Cretaceous igneous para-autochthonous Quebradagrande Complex and accreted Late Cretaceous oceanic crust of the Calima Terrane, complemented by multiphase 40Ar/39Ar crystallization and cooling ages. The geochronological data are combined with whole rock major oxide, trace element and REE data acquired from the same units to constrain the tectonic origin of the rock units and terranes exposed in the Western Cordillera, Cauca?Patía Valley and the Central Cordillera of Colombia. Continental arc magmatism during 180?145 Ma is preserved along the whole length of the Central Cordillera, extends throughout the Eastern Cordillera of Ecuador. The Caribbean Large Igneous Province collided and accreted to South America during ~75?70 Ma along the Cauca?Almaguer Fault, resulting in the cessation of both arcs and the Paleocene onset of subduction beneath the accreted oceanic c
