Group of gneiss quarries located near the village of Cadarese, which includes:

- Rio Fiume quarry, located at an elevation of 750-900 m SSW of Cadarese, on the right side of the Antigorio valley;

- Fruetta quarry, located at an elevation of 740-860 m in front of Cadarese, on the left side of the Antigorio valley near Rio Fruetta;

- San Rocco quarry (San Rocco-Alpe Croppo quarry), the larger quarry in this area, located at an elevation of 750-1000 m NE of the village of San Rocco di Premia, on the left side of the Antigorio valley.

All of these quarries are excavated in a dark grey coarse-grained orthogneiss called "Antigorio Gneiss". Crystallised minerals are mostly found in open alpine-type fissures generally orthogonal to the main schistosity. Rarer hydrothermal veins of white quartz occur, sometimes embedding centimetric crystals of milky white glassy "apatite".

Provided coordinates refer to the Fruetta Quarry.
