Galleria di Ronco (Finestra di Bedretto; Finestra di Ronco) [sezione sud], Bedretto, Distretto di Leventina, Ticino, Svizzera
South section of the access tunnel to the Furka base tunnel. The Bedretto tunnel was built in the 1970s as an auxiliary access drift to the Furka base tunnel. After completion of the Furka base tunnel, it was completely abandoned. The portal of the 5.22-km-long Bedretto tunnel is located close to the village of Ronco, southeast of Pizzo Rotondo.
The tunnel penetrates the Variscan Rotondo granite, which intruded the Palaeozoic polymetamorphic crystalline basement rocks of the Gotthard massif
at 294.3 Β± 1.1 Ma. The major mineral components of the Rotondo granite are albite, K feldspar, quartz, muscovite and biotite. Epidote-clinozoisite, chlorite, zircon, titanite, and carbonates are present as accessory minerals. Amongst opaque ore minerals pyrite is most abundant.
