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”

[Article] Multiple P–T–d–t paths reveal the evolution of the final assembly of the supercontinent Nuna (1.6–1.5 Ga) in NE Australia
EN | The integration of petrochronology with metamorphic petrology and petrostructural analysis allowed to identify two discrete metamorphic and deformation stages in the Proterozoic Georgetown Inlier (NE Australia). Robust and precise Lu–Hf geochronology determined garnet growth at 1.6 Ga (M1/D1), which was supported by a similar age from in–situ monazite geochronology. Medium-P/T metamorphism (M1) duringContinue reading “[Article] Multiple P–T–d–t paths reveal the evolution of the final assembly of the supercontinent Nuna (1.6–1.5 Ga) in NE Australia”
[Article] Structural Evolution of a 1.6 Ga Orogeny Related to the Final Assembly of the Supercontinent Nuna: Coupling of Episodic and Progressive Deformation
EN | In this contribution a multiscale structural and microstructural approach is applied to unravel the tectono-metamorphic history of a Proterozoic orogenic belt in NE Australia related to the 1.6 Ga assembly of the supercontinent Nuna. Three main deformation stages and associated composite fabrics were identified in the Georgetown Inlier in NE Australia. Coupling ofContinue reading “[Article] Structural Evolution of a 1.6 Ga Orogeny Related to the Final Assembly of the Supercontinent Nuna: Coupling of Episodic and Progressive Deformation”
