Within the Severin Nappe (as defined by Codarcea, 1940) there have been separated the Firizu Nappe, of Austrian age, at the upper part, and the Obârsia Unit, consisting of an ophiolithic complex, at its lower part. The Austrian Getic Megastructure (the I-st phase Getic Nappe: Codarcea, 1940; withouth the Obârsia Unit) would consist of several Austrian digitations (scales), some of them of nappes type (Firizu, Borascu, Godeanu, Plesiva, Sasca-Gornjac). The thrust plane of the Postaustrian Getic Megastructure (the II-d phase Getic Nappe: Codarcea, 1940) would be located beneath the Obârsia Unit rocks.
