Definition of geochronology in US English:



  • The branch of geology concerned with the dating of rock formations and geological events.

    • ‘Our geochronology has identified major early Ordovician magmatism within the Slishwood Division.’
    • ‘Large-scale tectonic reconstructions depend on linked and reliable geochronology and palaeomagnetic data.’
    • ‘The assignment of a particular suite of granites to one of these tectonic settings requires detailed knowledge of its structural setting, geochronology and chemistry.’
    • ‘The results of integrated field mapping and geochronology provide evidence for three major tectonothermal events.’
    • ‘In view of the new geochronology, the Finnmarkian Orogeny cannot have played any part in the deformation of the Hellefjord Schist.’
