Abstract
El origen y la evolución de la corteza continental continúa siendo uno de los enigmas más significativos y fundamentales en las Ciencias de la Tierra. A lo largo de la historia del planeta, la corteza continental ha sufrido innumerables eventos responsables de su creación, destrucción y modificación. Dichos procesos son la causa de que el registro rocoso represente una amalgama de la continua evolución de la corteza continental, ocultando las evidencias claras sobre su origen y los mecanismos responsables de su creación. En este sentido, el crecimiento cortical puede describirse como un proceso ígneo que involucra la segregación de material ígneo desde el manto y su subsiguiente incorporación y preservación a largo plazo en la corteza continental. Por consiguiente, el estudio de la petrogénesis del magmatismo más voluminoso del mundo representado por las dos suites constituyentes del magmatismo tipo I, a saber los magmas post-colisionales y cordilleranos, resulta de máxima prioridad a la hora de determinar el origen y evolución de la corteza continental...
The origin and evolution continental crust remains one of the most significant and fundamental issues in Earth Sciences. Throughout the history of the planet, the continental crust has undergone innumerable events that are responsible for its creation, destruction and modification. Such processes have resulted in the rock record representing an amalgamation of the ongoing evolution of the continental crust, hindering clear evidence on its origin and the mechanisms responsible for its creation. In this regard, crustal growth can be conceptualised as an igneous process involving the segregation of igneous material from the mantle and its subsequent incorporation and long-term preservation into the continental crust. Consequently, constraining the petrogenesis involving the most voluminous magmatism as represented by the two constituent suites of I-type magmatism, namely post-collisional and cordilleran magmas, is of paramount importance in constraining the origin and evolution of the continental crust...
