The Cavradi gorge forms the northern exit of the Val Curnera.

The central part of the gorge cuts through Permian and Carboniferous rocks of the Urseren-Gavera zone, belonging to the Gotthard massif. These rocks consist of mica schists and gneisses that contain zones with a high concentration of Alpine-type fissures. The famous iron rose specimens with epitactically overgrown rutile and copper minerals (djurleite, digenite, etc.) come from this part of the gorge.

To the north, the gorge cuts through gneisses of the "Tavetscher Zwischenmassiv" with differing mineralization ("anatase zone") that also contains a lot of Alpine-type fissures.

To the south, close to the Lai da Curnera reservoir, paragneisses of the Gotthard massif are exposed; these rocks are relatively poor in pockets and minerals. (Hager et al. 2013)
