The interpretation of reaction textures in Fe-rich metapelitic granulites of the Musgrave Block, central Australia: constraints from mineral equilibria calculations in the system K2O-FeO-MgO-Al2O3-SiO2-H2O-TiO2-Fe2O3
TL;DR: In this paper, the early reaction textures associated with spinel and quartz-bearing symplectites are separated by later garnet and/or sillimanite coronas in the Musgrave Block, central Australia.

Metamorphic Conditions in Orogenic Belts: A Record of Secular Change
TL;DR: The abundance and scale of ultra-high-temperature (UHT) metamorphic belts from the Neoarchean to the Cambrian imply a significant change in geodynamics during the Neo-Archean Era, after which transient sites of high heat flow were available at intervals throughout this period of Earth evolution as mentioned in this paper.

Temperature dependence of Zr in rutile: empirical calibration of a rutile thermometer
TL;DR: In this article, the effects of temperature (T) and pressure (P) on the Zr content in rutile have been empirically calibrated in this study by analysing rutiles-quartz-zircon assemblages of 31 metamorphic rocks spanning a T range from 430 to 1,100°C.

Temperatures of Granulite-facies Metamorphism: Constraints from Experimental Phase Equilibria and Thermobarometry Corrected for Retrograde Exchange
TL;DR: Pattison et al. as mentioned in this paper applied a thermobarometry method to 414 granulites of mafic, intermediate and aluminous bulk compositions and found that they are much hotter than traditionally assumed and that the P±T conditions of the amphibolite±granulite transition portrayed in current petrology textbooks are significant underestimates by over 100 C.

On the occurrence and characterization of ultrahigh-temperature crustal metamorphism
TL;DR: In this article, the peak pressure-temperature (P-T) conditions of several UHT occurrences were defined and the post-peak P-T paths delineated and further experimental constraints on quartz-absent assemblages at UHT conditions were provided.
