Water plays a critical role in erosion and sediment transport and this relationship is most
evident in the hyperarid Atacama Desert of Northern Chile, a region characterized by …

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 …

The availability of thermodynamic data for geologically relevant phases has made practical
the calculation of stable phase relations throughout the mantle and crust of terrestrial …

The Th/U ratios of zircon crystals are routinely used to help understand their growth
mechanism. Despite the wide application of Th/U ratios in understanding the geological …

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 …

Granitoids are a major component of the continental crust. They play a pivotal role in its
evolution, either by adding new material (continental growth), or by reworking older …

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 …

For petrological calculations, including geothermobarometry and the calculation of phase
diagrams (for example, P–T petrogenetic grids and pseudosections), it is necessary to be …
