Post-Archean granitic rocks: contrasting petrogenetic processes and tectonic environments

Publication at Faculty of Science |
2020

Abstract

Granitic rocks represent a ubiquitous component of upper continental crust but their origin remains highly controversial. This controversy stems from the fact that the granites may result from fractionation of mantle-derived basaltic magmas, or partial melting of different crustal protoliths at contrasting P-T conditions, either water-fluxed or fluid-absent.

Consequently, many different mechanisms have been proposed to explain the compositional variability of granites ranging from whole igneous suites down to mineral scale. This Special Publication presents an overview of the state of the art, as well as envisages future avenues towards a better understanding of granite petrogenesis.
