Stratigraphy. „The potential Upper Jurassic aquifer ranges from 3992 – 4404 mMD. Yellowish-brown micritic limestones containing residues of siliceous sponges were developed here from 3992 – 4280 mMD, a dark-grey micrite with sponge needles (basinal limestones) from 4280 - 4375 mMD, ▇▇▇▇▇ calcisiltites down to 4404 mMD, and Dogger rocks down to 4450 mMD. In place of the expected ▇▇▇▇▇▇▇ limestones (Helvetian facies), Swabian sponge mass facies were found. Dolomites causing the good permeabilities in the eastern Molasse Basin could only be observed subordinately. Indications of karstification, open porosities and fractures were only scarce. Increased quantities of transparent calcites could be observed only at 4070 mMD and from 4150 –4210 mMD; white calcites observed from 4315 – 4335 mMD indicate a fault zone with closed fractures.
