Definition of petrogenesis in English:



mass nounGeology
  • The formation of rocks, especially igneous and metamorphic rocks.

    • ‘The petrogenesis of igneous rocks in the Albany-Fraser Province is not well constrained, although U-Pb zircon geochronology establishes that most granitic protoliths were not tectonically reworked Yilgarn Craton.’
    • ‘The petrogenesis and tectonic setting of the supersuite, and cogenetic felsic volcanic rocks, has been discussed in some detail by Griffin et al..’
    • ‘Petrogenesis Igneous petrogenesis is the process or set of processes by which igneous rocks are formed.’
    • ‘Most arc magmas have also undergone complex fractionation and contamination paths, which make attempts to quantify their petrogenesis difficult.’
    • ‘Some back-arc basalt samples from the East Scotia Sea have high alumina characteristics, suggesting the involvement of subduction-modified mantle sources in their petrogenesis.’
