Abstract

The present Project includes two main themes which are closely linked. Combined studies, including whole-rock chemistry, geochronology, and isotope data are designed to answer the questions about of the growth and evolution of the continental crust as well as geodynamic setting during the Devonian-Carboniferous time of the pre-Andean margin of SW Gondwana. In particular, integrated geochronological and isotope studies are relevant to characterizing the magmas involved, the degree of crustal reworking the formation and stabilization of new continental crust by juvenile material accretion. The referred studies will contribute to understand the controversial geodynamic setting during the Devonian-Carboniferous time. Two topics are the most relevant in this research project: 1) Continent formation through of the Devonian and Carboniferous time in the pre-Andean margin SW Gondwana; 2) The great controversy: the geodynamic setting during the Devonian-Carboniferous time in the pre-Andean margin SW Gondwana.
