Abstract Fe3+ and XFe3+, defined as Fe3+/(Fe2++ Fe3+) on a molar basis, are now
recognised as key parameters in phase equilibrium modelling. A hindrance is that it is only …

Early continent-building processes on Earth are challenging to investigate, particularly since
juvenile felsic crust formed during the Early Archean (4.0–3.2 Ga) is rarely preserved. Thus …

Abstract Tonalite-trondhjemite-granodiorite (TTG) suites constitute a large proportion of the
Archean geological record; however, the geodynamic processes that generated them, and …

In this contribution, we analyzed a pair of mafic samples collected from a recently identified
shear zone and its proximal footwall from the Manicouagan Imbricate Zone (MIZ) of the …

This review presents an objective account of metamorphic, microstructural and
geochronological studies in the Greater Himalayan Sequence (GHS) and adjacent units in …

The garnet megacrysts of Gore Mountain (Adirondacks, US) are world-renown crystals due
to their size, up to 1 m in historical record, which makes them the largest known garnets on …

Abstract Tonalite–trondhjemite–granodiorite (TTG) gneiss forms a major component of
Archean continental crust. Resolving the origin of TTG gneisses and the secular change in …

Granulites represent high-grade metamorphic rocks of the deep continental crust. The
metamorphism and exhumation of granulites from Archean terranes provide insights into the …

Different geodynamic models exist for the growth and differentiation of Archean continental
crust, ranging from horizontal tectonics with subduction zones to vertical tectonics with …

Phase equilibrium modelling is a powerful method for obtaining pressure–temperature (P–T)
estimates in metapelites; however, the advantages, disadvantages, and limitations of …
