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

This chapter presents an overview of diffusion data for pyroxenes, amphiboles and micas.
These minerals are grouped together since amphiboles and micas are closely related in …

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

Rutile is an important carrier of high field strength elements (HFSE; Zr, Nb, Mo, Sn, Sb, Hf,
Ta, W). Its Zr content is buffered in systems with quartz and zircon as coexisting phases. The …

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

Rocks of basic and intermediate bulk composition occur in orogenic terranes from all
geological time periods and are thought to represent significant petrological components of …

This study assesses temperatures of formation of common granulites by combining
experimental constraints on the P–T stability of granulite-facies mineral associations with a …

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 …

Anatectic stromatic migmatites have a symmetrical layered structure with a low ratio of
thickness to length and a periodicity, features that have not been explained satisfactorily but …

Detailed textural observations and in situ analyses (EMP, SIMS and LA-ICP-MS) are used to
characterize trace element behavior during prograde and retrograde metamorphic reactions …
