TL;DR: The discovery of 16 Ma UHT granulites from the Kobipoto Mountains of Seram in eastern Indonesia has been reported in this paper, where they were shown to have required temperatures of ∼950 °C at ∼8 kbar pressure.

TL;DR: In this paper, the age of peak metamorphism of Barrovian migmatites was calculated using the SHRIMP U/Pb zircon ages of 472.2 ± 5.9 Ma and 471.2± 5.8 Ma, respectively.

TL;DR: In this article, the authors provide a synthesis of existing data from the European Alps, supporting the hypothesis on tectonic mode switches, and suggest that at ca. 38-34 Ma, a period of N-S (orogen perpendicular) shortening led to the formation of medium to ultra-high-pressure mineral assemblages by lithosphere-scale thrust imbrication.

TL;DR: In this article, a strong correlation is observed between measured ages, mica composition and deformation fabrics, allowing to estimate an age of 44.4 ± 0.4 ǫ for the formation of phengite-bearing fabrics in eclogite facies conditions (S HP ) and 42.0 − 0.5 Á± 0.1 ÁÁ for the microstructurally younger muscovite bearing shear fabrics, which formed in greenschist facies condition (SZ gr1 ).

TL;DR: In this article, the authors presented new geochemistry, zircon U-Pb and 40Ar/39Ar age data from igneous and metamorphic rocks from the Schwaner Mountains to investigate their tectono-magmatic histories.
