Figure 1: Geographic context of the studied area. The main image shows the satellite orthophoto of a portion of Massiccio dei Laghi batholith. In the northern part of the map (Montorfano area), it is possible to individuate both the white granite (represented by grey stripes) and the green granite portion (green Mergozzo type, represented by green stripes). The orange area defines the Baveno-Mottarone pluton. Furthermore in the image the exploited quarry dumps (red points) are represented and the ancient quarry waste areas, potentially useful for a future valorisation (yellow points).
