Abstract

The retention of the original, literal meanings of "orogeny" and "epeirogeny" is recommended. Orogeny is not a short-lived, chronostratigraphic feature nor is it a synonym for rock deformation or for widespread isotopic events. The term is applicable to tectonic deformation in belts, and which produced chains of mountains in Phanerozoic (and late Proterozoic) rocks. Therefore, it maybe less appropriate in Archean rocks of the shield areas where broadly uniform isotopic events may be more appropriately considered as epeirogenetic phenomena.
