Mechanical consequences of granite emplacement during high-T, low-P metamorphism and the origin of “anticlockwise”PT paths
TL;DR: In this paper, a simple coupled thermal-mechanical model was proposed for the continental lithosphere and it was shown that the coincidence of metamorphism with convergent deformation in high-T, low-P terrains may reflect the thermal weakening attendant with rapid advective movement of heat within the lithosphere via granite magma ascent.

High-precision geothermobarometry across the High Himalayan metamorphic sequence, Langtang Valley, Nepal
TL;DR: In this article, the ΔPT-based approach was applied to the thermobarometric data from the Langtang valley section of the Higher Himalayan Crystallines, which significantly improved the precision to which pressure and temperature differences between samples may be calculated.

TL;DR: In this article, detrital zircons from sandstones in various tectonic blocks of the New England Orogen are dated by the U-Pb SHRIMP and LA-ICPMS techniques and Detrital hornblendes by the Ar-Ar technique to constrain the age and provenance of sedimentary rocks in the accretionary wedge.

Age of the Ballachulish and Glencoe Igneous Complexes (Scottish Highlands), and paragenesis of zircon, monazite and baddeleyite in the Ballachulish Aureole
TL;DR: In this paper, the ages of the Ballachulish Igneous Complex and the Glencoe Volcanic Complex of the Scottish Highlands have been investigated using the metamorphic behavior of the U-bearing accessory minerals baddeleyite, zircon and monazite.

Timing and rate of isothermal decompression in Pan‐African granulites from Rundvågshetta, East Antarctica
TL;DR: Geochronological data, combined with field and petrological evidence, constrain the timing and rate of near-isothermal decompression at granulite facies temperatures in rocks from the Lutzow-Holm Complex of East Antarctica.
