St Gotthard-Straßentunnel (Nordabschnitt), Göschenen, Reusstal

Road tunnel connecting Göschenen (Canton Uri) with Airolo (Canton Tessin); part of the Swiss National road A2. The longest road tunnel in the Alps, constructed in 1970-1980.
The construction of a second tunnel tube was approved in 2016.

The tunnel's south section is a separate locality.

Known for outstanding specimens found in Alpine-type clefts (in gneiss) during the construction works.

Geochronology

Mineralization age: Carboniferous : 299 ± 2 Ma

Important note: This table is based only on rock and mineral ages recorded on mindat.org for this locality and is not necessarily a complete representation of the geochronology, but does give an indication of possible mineralization events relevant to this locality. As more age information is added this table may expand in the future. A break in the table simply indicates a lack of data entered here, not necessarily a break in the geologic sequence. Grey background entries are from different, related, localities.
