... the folded succession. Considering the inferable tectonic features of the Sardic Phase in SE Sardinia (deformation style, structural level, lack of exhumation of lower crust, small uplift) we suggest that the Sardic compression event did not necessarily develop in an Andean-like orogenic context, as commonly...

... of the post-Sardic phase. Conversely, in various tectonic units within the nappe zone, an arc-related post-Sardic volcanic suite occurs immediately above thin metaconglomerates (metaconglomerati di Muravera) or directly on top of the pre-Sardic metamorphosed deposits. The succession of metandesites...
