U–Pb and trace element zircon and apatite petrochronology of eclogites from the Scandinavian Caledonides
The petrochronological records of eclogites in the Scandinavian Caledonides are investigated using EPMA and LA-ICPMS of zircon and apatite for U–Pb...

Dating corona formation in high-grade rocks: integrated garnet and zircon petrochronology of granulite-facies rocks in the North China Craton
Corona textures, characterized by specific mineral assemblages as layers between existing phases, are frequently observed in high-grade metamorphic...

Zircon petrochronology in large igneous provinces reveals upper crustal contamination processes: new U–Pb ages, Hf and O isotopes, and trace elements from the Central Atlantic magmatic province (CAMP)
Zircon occasionally crystallizes in evolved melt pockets in mafic large igneous province (LIP) magmas, and in these cases, it is used to provide...

Genesis of baddeleyite and high δ18O zircon in impure marble from the Tongbai orogen, Central China: insights from petrochronology and Hf–O isotope compositions
Coexistence of baddeleyite and zircon is rarely documented in metacarbonate rocks and poorly understood. In this study, metamorphic baddeleyite and...

Mechanisms to generate ultrahigh-temperature metamorphism
Ultrahigh-temperature (UHT; T max ≥ 900 °C) metamorphism requires unusually high heat in continental crust at depths of 15–55 km, but how such extreme...
