Etude geologique de la rive occidentale du lac de Garde de Bogliaco a Salo et des regions situees a l'est de Brescia (Alpes meridionales, province de Brescia, Italie)

Abstract

Abstract The stratigraphic section exposed on the west bank of Garda lake and the northern Po plain, northern Italy, represents continuous marine sedimentation from the lower Jurassic to the Lutetian (Eocene), followed by isolated outcrops of Oligocene to Pliocene deposits as young as Calabrian. The two regions studied belong to the Judicarian tectonic phase which produced NNE-SSW oriented structures. The Mesozoic-Tertiary series is represented by varying facies, from thin neritic limestones in the lower Lias to conglomerates, sands, and clays in the Pliocene. These deposits occupy the east flank of the Lombardy trough and were influenced by the Tridentine fold system to the east. The deposits suggest that the area is a transition zone between the Lombardy to the west and the Tridentine to the east.
