The thermal history of the Eastern Ghats Belt (India) as revealed by U–Pb and 40Ar/39Ar dating of metamorphic and magmatic minerals: implications for the SWEAT correlation
Klaus Mezger,Michael A. Cosca +1 more
TL;DR: The Eastern Ghats belt is a large high-grade terrane exposed along the east coast of India as mentioned in this paper, which represents an important part of the reconstructed global Southwest-United States-East-Antarctica (SWEAT) orogen.

Variscan Sm-Nd and Ar-Ar ages of eclogite facies rocks from the Erzgebirge, Bohemian Massif
TL;DR: The Erzgebirge Crystalline Complex (ECC) is a rare example where both "crustal" eclogites and mantle-derived garnet-bearing ultramafic rocks (GBUs) occur in the same tectonic unit as mentioned in this paper.

In-situ UV-laser 40Ar/39Ar geochronology of a micaceous mylonite : an example of defect-enhanced argon loss
TL;DR: In this article, deformed muscovite and biotite from a crustal-scale mylonite zone (Pogallo Shear Zone, southern Alps) were investigated using furnace step-heating and in-situ UV-laser ablation 40Ar/39Ar geochronology.
Reconstructing paleoelevation in eroded orogens
TL;DR: In this article, the authors used the isotopic composition of surface-derived waters in extensional detachments of the Shuswap Metamorphic Complex to estimate the early Eocene paleoelevations of the orogen.

Recrystallization or cooling ages: in situ UV-laser 40Ar/39Ar geochronology of muscovite in mylonitic rocks
Andreas Mulch,Michael A. Cosca +1 more
TL;DR: The age distributions of muscovite from greenschist-facies mylonite zones are shown to be sensors of metamorphic history in this article, showing that cooling ages can be distinguished from neo- or recrystallization ages.
