The Monte Cervino sheet (070) of the Geological Map of Italy, scale 1:50.000 (CARG Project - ISPRA), covers the high mountains of the Pennine Alps from the northern flank of the middle Aosta valley (423 km2) to the southern Valais (149 km2). This is a key area of the western Alps due to the birth and development of geological studies on Alpine tectonics, and is dominated by the Austroalpine-Penninic collisional wedge, a fossil subduction complex of continental and oceanic nappes. The Italian part of the sheet was surveyed on a scale of 1:10.000: the Italian working group was coordinated by Giorgio V. Dal Piaz and was composed of Andrea Bistacchi, Nicola Bistacchi, Giorgio V. Dal Piaz, Giovanni Dal Piaz, Matteo Massironi, Bruno Monopoli, Alessio Schiavo e Giovanni Toffolon, and also greatly benefited from collaboration by Leonsevero Passeri and Gloria Ciarapica. The Swiss part of the sheet was prepared at 1:50.000 scale, thanks to Yves Gouffon (swisstopo) and based on the Chanrion-Mont Velan (Burri et al., 1998) and Matterhorn sheets (Bucher et al., 2004) of the Geologischer Atlas der Schweiz, scale 1:25.000. The geological dataset (1:10.000, 1:25.000 and 1:50.000) has been implemented and validated in GIS environment by Land Technology & Services S.r.L under the supervision G.V. Dal Piaz and with the responsibility of the Regione Autonoma Valle d'Aosta. Starting from geometric primitives and alphanumeric attributes of Data Base at 1:50.000, LTS with the collaboration of La Nuova Lito S.n.c, made the cartographic layout and letterpress of the sheet and notes.
