Gravimetrische Untersuchungen fiber einer Salzstruktur in der Nӓhe von Lübbecke, Norddeutschland
A detailed gravity survey was conducted parallel to the “Wiehengebirge” northwest of Minden in Northern Germany. The survey localized between Liibbecke and Levern a salt deposit, which is known as “Münder Mergel” salt of the Upper Jurassic. The salt deposit forms a cylindrical structure with an axis striking NWW. With a deep drill hole detailed interpretation was possible using the polygon method of TALWANI, WORZEL and LANDISMAN , The section shapes of salt bodies under eight profiles show asymmetrical figures of two salt units. Both increase in thickness strongly to the northeast, where the salt is interrupted by a fault zone. Here the strong gradient of the residual anomaly can only be explained by an increase of thickness and rise of the upper salt unit to about 50 m below the surface. This accounts for a number of sulfur and salt wells along the strike direction of the fault zone.
