Erläuterung zur «Geologischen Karte der zentralen Nordschweiz 1:100 000»

A new geological map on a scale 1:100'000 is presented, covering the central part of Northern Switzerland and the adjoining regions of Baden-Württemberg. This map, a co-production of the NAGRA and the Swiss Geological Commission is a compilation of about 350 different maps and sketches, partly unpublished or out of print for a long time.

The explanatory text gives a popular review of the geological and tectonical history of the region and a short description of the main rock units. New results of the NAGRA research programm, including deep drillings and studies in Neotectonics, have been incorporated. The report is illustrated with numerous block diagrams, various key maps and coloured cross sections.
