Ultrahigh-temperature (UHT) metamorphism is the most thermally extreme type of crustal
metamorphism, with the crust capable of withstanding temperatures≥ 900° C. Mineral …

Ultrahigh temperature (UHT) metamorphism is the most thermally extreme form of regional
crustal metamorphism, with temperatures exceeding 900° C. UHT crustal metamorphism is …

Pseudosection modelling is rapidly becoming an essential part of a petrologist's toolkit and
often forms the basis of interpreting the tectonothermal evolution of a rock sample, outcrop …

Improved activity–composition relationships for biotite, garnet and silicate liquid are used to
construct updated P–T grids and pseudosections for high‐grade metapelites. The biotite …

The solubility of ZrO2 in rutile is strongly temperature‐dependent and has been identified as
a potentially powerful thermometer when the rutile coexists with an appropriate buffer …

Thermobarometry, the estimation of the pressure–temperature (P–T) conditions of
metamorphism, can be undertaken by using pseudosection calculations as well as by …

Abstract Ultra‐high‐temperature (UHT) metamorphism occurs when the continental crust is
subjected to temperatures of greater than 900° C at depths of 20–40 km. UHT …

Subduction infancy corresponds to the first few million years following subduction initiation,
when slabs start their descent into the mantle. It coincides with the transient (yet systematic) …

The Brasília Belt is one of the most complete Neoproterozoic orogens in western Gondwana.
Rapid progress on the understanding of the tectonic evolution of the belt was achieved due …

The opening-angle of quartz c-axis fabrics (OA) is strongly temperature dependent and has
proven to be a powerful deformation thermometer for natural metamorphic rocks. Previous …
