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 …

At the core of petrochronology is the relationship between geochronology and the
petrological evolution of major mineral assemblages. The focus of this chapter is on …

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 …

Trace element concentrations and ratios in zircon provide important indicators of the
petrological processes that operate in igneous and metamorphic systems. In granitoids, the …

Formation of continental crust has shaped the surface and interior of our planet and
generated the land and mineral resources on which we rely. However, how the early …

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 …

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 …

Metamorphic devolatilization of subducted slabs generates aqueous fluids that ascend into
the mantle wedge, driving the partial melting that produces arc magmas. These magmas …

Rocks of tonalitic–trondhjemitic–granodioritic (TTG) composition preserved in Archaean
terranes represent fragments of the Earth's earliest-formed continental crust, and are thought …
