WebOrogeny is a mountain building process. Epeirogenic processes: It involves the uplift or warping of large parts of the crust of the earth. Epeirogeny is a continental building process. Earthquakes comprising local, comparatively minor movements. Plate tectonics comprising horizontal movements of crustal plates. WebThe Grenvillian Orogeny, for which an age of ca. 1090–980 Ma is usually quoted based on its metamorphic signature (Fig. 2), was the result of continent-continent collision between Laurentia and another craton, inferred to be Amazonia (see below), and it marked the final closure of a long-lived ocean on the southeastern margin of Laurentia (present co …
