Geochronological constraints on the Paleozoic to Early Mesozoic geodynamic evolution of southern coastal Peru

TL;DRAbstract

The main objective of this dissertation was to establish a chronostratigraphic framework for the south Peruvian margin for the late Paleozoic to Mesozoic based on geochronological, geochemical and isotopic data on periods of magmatism and magmatic quiescence along the western Gondwana margin since the onset of subduction around 530 Ma ago. Our integrated geochronological study, revising the information of sedimentary basins and magmatism in southern coastal Peru (15-18°S) provide new insights in the evolution of this segment of the western Gondwana margin since the onset of subduction.
