The collision of the Indian, Arabian and Eurasian plates formed the Tibetan and Iranian plateaus, but its timing and processes remain debated. This Review explores the evidence behind initial collision estimates and discusses the tectonic and geodynamic implications. ...
combined with transient mantle flow and migrating proto-subduction, is proposed to explain the apparent emergence of plate tectonics three billion years ago; modelling confirms that tectonic plate boundaries and fully formed tectonic plates can arise under conditions characteristic of Earth but not of ...
