Switzerland has a new tectonic map at a scale of 1:500,000. It contains updates concerning the geometry, distribution and nomenclature of the tectonic units of Switzerland and surrounding regions.

The tectonic units include rocks with a similar evolutionary geodynamic history, the Federal Office of Topography (Swisstopo) said in a statement on Wednesday. This fourth edition of the tectonic map is based on the previous one, dating from 2005, and integrates the different geological maps published since then.

For the first time, it is accompanied by an explanatory note in English which briefly describes the 187 tectonic units represented. It also addresses the nomenclature and interpretation of these units.

The digital version of the map also provides access to some 200 subunits, allowing a more detailed understanding of the Swiss subsoil. Finally, the colors of the map have been revised to better highlight the link between the crystalline bases and the sedimentary layers deposited on top.

Two new areas

Furthermore, two new areas are mentioned. The Leponticus, formerly considered a subunit of the Pennic domain, is now identified as a region in its own right. It lies at the edge of the ancient European plate and includes geological units specific to the Lepontine Alps.

The Salassic brings together certain units formerly included in the Austroalpine domain, but which have a distinct tectonic and metamorphic history. This name refers to the Celtic tribe of Salasses, who settled in Val d’Aosta and the region of Sesia at the same time as the Helvetii north of the Alps and the Lepontians between Val d’Ossola and Leventina.
