Description
The sheets of the Geological Atlas of Switzerland (GA25) give detailed information about the uppermost layers of the subsurface structure. Geological formations are represented by colours, conventional signs and symbols, which correspond to their age, composition and tectonic structure. For each sheet, an explanatory booklet is also published, in which the geological formations and special features of the study area are described. Over two thirds of the 220 map sheets that are planned have already been published.
