The route of the tunnel Subir mainly passes through layers foraminiferal limestones Paleocene - Middle and Upper Eocene (V; Pc-E1,2) and rudist limestone of the upper Cretaceous (V; K2), and it is important to point out the presence of flysch deposits of the Middle and Upper Eocene (F(L); E2,3). Blue-gray layers of flysch marls prevail along with reverse fault in contact with very weathered foraminiferal limestones, and these build the west region of the tunnel while central and east region of the tunnel is comprised of rudist limestones. At contact regions of flysch sediments and foraminiferal limestones (reverse fault zone) there is regular appearance of undergroundwater in the periods of higher precipitation.
