Craton Destruction Induced by Drastic Drops in Lithospheric Mantle Viscosity
Earth and Space Science, 2022 The disruption of the mantle roots of cratons is common after cratonization. Craton destruction, which is characterized by severe lithospheric thinning, extensive thrust and extensional deformation, basin filling, and intense thermal activities, is ...
