| Zusammenfassung |
| In northern Germany, the evaporitic sequence of Zechstein rocks outcrops at several
locations, offering insight into both surface and sub-surface morphology of the soluble
rocks.
We discuss two field sites, an active shallow gypsum cave in the southern Harz
Mountains, and an active shallow anhydrite/gypsum cave close to Bad Segeberg, which both
have been explored from the surface by geophysical surveys. The overburden of the caves
varies from 5-40 meter, and the caves are characterised by both small passages and larger
breakdown chambers.
We relate the indirect geophysical measurements to parts of the known cave systems, and
present structural models describing both geometry and groundwater flow in these caves with
the help of numerical tools. |
