Orogenesis: a New Definition


In GSST (Global Strike-Slip Tectonic) approach, orogenesis defines the main space shortening process of transpressional shear zones, involving the coalescence of various, different scale and hierarchy crustal fragments, i.e. piko-, nano- and microplates. Initial push-up ranges or (proto-orogenes) evolve into orogens by the means of horizontal and vertical duplexing mechanisms.
