The crustal evolution of South America from a zircon Hf‐isotope perspective

Abstract: Hf‐isotope data of >1100 detrital zircon grains from the Palaeozoic, south‐central Andean Gondwana margin record the complete crustal evolution of South America, which was the predominant source. The oldest grains, with crustal residence ages of 3.8–4.0 Ga, are consistent with complete recycling of existing continental crust around 4 Ga. We confirm three major Archaean, Palaeoproterozoic (Transamazonian) and late Mesoproterozoic to early Neoproterozoic crust‐addition phases as well as six igneous phases during… Show more

“…There is a relatively low statistical dissimilarity to the South American sources including the Sunsás domain, and the respective ages contained in the Puncoviscana Formation and the Ordovician sedimentary rocks of northern Bolivia and southern Peru. This relatively close connection is in keeping with the available geological evidence (Reimann et al, 2010;Reimann Zumsprekel et al, 2015;Augustsson et al, 2016;Pepper et al, 2016). The closest statistical neighbor to the Chilla beds is the Puncoviscana Formation, followed by the Ordovician sedimentary rocks of northern Bolivia and southern Peru (Fig.…”

“…6). We have chosen the time interval 570-680 Ma, corresponding to the Brasiliano-Pan-African orogeny, for this comparison, using data from North Western Argentina (Hauser et al, 2011;Augustsson et al, 2016) and sample TLT-2069 (Table 2) along with data from the Saldania Belt (Frimmel et al, 2013). The Hf t values of the latter (+4.74 to -19.24) are for the most part negative and coincident with those of the Puncoviscana Formation (+ 5.8 to -18.4), suggesting Brasiliano-Pan African sources for both (Frimmel et al, 2013).…”

“…Proterozoic Nd model ages of the Granjeno Schist and of the Novillo Gneiss and along large parts of the Gondwana margin indicate that the protolith material was produced partly from rather juvenile mantle material (cf. Augustsson et al, 2016). Even though crustal recycled components of the Novillo Gneiss (or equivalents) were further recycled into protoliths of the Granjeno Schist, a degree of juvenile isotopic imprint seems to persist.…”
