[LPT] Electron Microprobe U-Th-Pb Monazite Dating

En | Monazite is widely used in petrochronological studies, as it is one of the most common radioactive minerals and one of the main hosts of U and Th in igneous and metamorphic rocks. Among the different methods used for its dating, the electron microprobe stands out for its operational cost and spot size considerablyContinue reading “[LPT] Electron Microprobe U-Th-Pb Monazite Dating”

[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”
