▪ Abstract The subducted lithosphere is composed of a complex pattern of chemical systems
that undergo continuous and discontinuous phase transformation, through pressure and …

Garnet could be the ultimate petrochronometer. Not only can you date it directly (with an
accuracy and precision that may surprise some), but it is also a common rock-forming and …

A set of thermodynamic models is presented that, for the first time, allows partial melting
equilibria to be calculated for metabasic rocks. The models consist of new activity …

New activity–composition (a–x) relations for minerals commonly occurring in metapelites are
presented for use with the internally consistent thermodynamic dataset of Holland & Powell …

The geodynamic environment in which Earth's first continents formed and were stabilized
remains controversial. Most exposed continental crust that can be dated back to the …

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

The a–x relations recently presented in White et al.(, Journal of Metamorphic Geology, 32,
261–286) are extended to include MnO. This provides a set of internally consistent a–x …

Granite petrogenesis is associated with the formation and evolution of continental crust
along convergent plate boundaries. While magmatic processes such as partial melting and …

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 …

Thermometry of high-grade metamorphic rocks is difficult due to fast cationic diffusion during
slow cooling, but the titanium content of calcium amphibole (Ti-Amp) can retrieve amphibole …
