How did the soil on which people live come about? What was it like here millions of years ago? What influence did and do geological formations have on agriculture and industry? The series “Geo-Tour” takes up these and many other questions. The cinematic excursion leads to quarries, caves, mines and to geotopes worthy of protection.
