Alpine deformations. Huge pluridecametric F4 folds in the most external portion of the EMC “Eclogitic Micaschist Complex” (retrogressed eclogites with greenshist facies imprint) of the Sesia-Lanzo Zone Unit (nappe of the Australpine domain), adriatic (paleoafrican) subducted ex continental margin. Outcrop exposed along the Roman consular road from Donnas to Bard (AO) spur, Aosta Valley region. Outcrop related to “Fig. 8 – (a) View of the outcrops exposed along the Roman consular road at Bard, not far from Stop 4.” outcrop described at page 32 of the paper “Valle d’Aosta section of the Sesia Zone: multi-stage HP metamorphism and assembly of a rifted continental margin” – 10th International Eclogite Conference – Courmayeur (Aosta, Italy), Compagnoni, Engi, Regis – Geol.F.Trips, Vol.6 No.1.2 (2014), Periodico semestrale del Servizio Geologico d’Italia – ISPRA e della Società Geologica Italiana.
