The Precambrian to Paleozoic crustal growth of South America: From collisional to accretionary tectonics

Abstract

Southern South America hosts a vast geologic record of Precambrian to Paleozoic geodynamic and tectonic processes, particularly related to the assembly and crustal growth of Western Gondwana. This special volume comprises 24 novel contributions focused on the Precambrian to Paleozoic tectonic evolution of southern South America, focused on different tectonostratigraphic domains of southeastern Brazil, Uruguay, Argentina and Chile (Figs. 2, 3). Papers also cover a wide temporal frame, including Archean to Tonian processes of pre-Brasiliano basement inliers; the tectonometamorphic, magmatic and sedimentary record of the late Neoproterozoic Brasiliano Orogeny, particularly related to the Dom Feliciano Belt; and Paleozoic accretionary systems of the proto-Pacific margin (Fig. 4).
