Stage 12: The eroded valley of the Franscinone

The Franscinone valley is a good example of a "valley formed by erosion" and from here we have a good view over the gorge hollowed out by the torrent.

The valleys formed by erosion have been hollowed out in the rocks by the strength of the water and bring to light geological events that took place during millions of years. Here the torrent hollowed out metamorphic rocks of Gneiss of Stabbiello and hornblende schists and epidotes, which were formed more than 280 million years ago. As at the 6th stop, we can see on the opposite side of the valley an area of contact between these two rocks.

The outcrop of Gneiss of Stabbiello along this path, often covered with earth and humus on the upper part where different species of ferns grow, is the ideal habitat for many invertebrates, which prefer the cool and humid microclima and where they shun the light. These animals play an important ecological role in the decomposition of organic material. They eat the debris of vegetation and animal origin and transform them into humus, rendering the soil fertile. The plants then reabsorb the substances produced by these organisms and transfer them into organic matter. To this category of animals belong the Diplopodans (commonly called millipedes), whose segments have two pairs of limbs, the Chilopodans (or centipedes), with segments with only one pair of limbs, and the Isopods (also called "woodlice"), which are crustaceans that have adapted themselves to life on dry land.
