[Article] Zircon petrochronology reveals the moderately juvenile signature of a diatexite from the boundary zone between the Brasília and Ribeira orogens (SE Brazil): Relict of a Tonian arc?
EN | How fun is to find an exception to the rule?In our contribution we report a biotite-bearing granitic leucosome from Socorro-Guaxupé nappe of the Southern Brasília orogen with an anomalous juvenile-like signature.The zircon extracted from this rock yield a protracted spread of U–Pb ages from ca. 890 Ma to ca. 540 Ma and theContinue reading “[Article] Zircon petrochronology reveals the moderately juvenile signature of a diatexite from the boundary zone between the Brasília and Ribeira orogens (SE Brazil): Relict of a Tonian arc?”
[Article] Spatio–temporal evolution of Mesoproterozoic magmatism in NE Australia: A hybrid tectonic model for final Nuna assembly
EN | Fun, Fun, Fun!! Do you like puzzles and untangling conundrums? Then, check out our proposed tectonic model to explain the tectonic regimes operating back in the Proterozoic (c. 2.0 Ga to 1.4 Ga), when the oldest supercontinent known today, Nuna, formed.In this contribution, we combined previous structural and metamorphic studies with zircon Lu-HfContinue reading “[Article] Spatio–temporal evolution of Mesoproterozoic magmatism in NE Australia: A hybrid tectonic model for final Nuna assembly”
[Tips] Zircon role in Petrochronology
EN | Zircon is a petrochronology superstar and here is why: besides being a very robust chronometer, it can record different geological conditions during the formation of a rock. For example, are you aware that zircon morphology may constrain the temperature in which it was crystallized? Within this context, Araujo et al. (2020) explored zirconContinue reading “[Tips] Zircon role in Petrochronology”
