Die Höhenlage der Schichtengrenze Tertiär—Quartär im mittleren Oberschwaben.

Abstract. For the first time we submit a map showing the altitude of the tertiary-quaternary-boundary in a larger area of the Württemberg prealpine highland. The region that has been investigated covers an area of 310 km². It is covered with about 20 km³ of quaternary sediments. About 5 km³ can be allotted to the Wurzach basin and almost 6 km³ to the relatively small part of the recently explored area in the Schüssen basin. This map of the lower boundary quaternary sediments (table) admits of interesting conclusions and it is of particular importance to the glacial morphology.
