5 Project team project workers: 4 project workers (full time) ca. 20 other persons (permanent staff, part time) Basel 2009 run time: 3 years (1. october 2008 to 30. september 2011) 5

6 Geology lithostratigraphic record Cenozoic rift and wrench basin Thickness of Cenozoic graben fill: up to 3.5 km (sediments including salts) local volcanic activity (diatremes, Miocene effusives) Mesozoic and Posthercynian sediments (Permian Upper Jurassic) crystalline basement: hercynian deformed metamorphic and magmatic rocks Geopotentials can be found in every depositional complex! 6

5 km (sediments including salts) local volcanic activity (diatremes, Miocene effusives) Mesozoic

7 Geology tectonic structures Cenozoic rift and wrench basin closely spaced Cenozoic fault systems 4-5 km extension, km sinistral strike slip offset normal faults, transtensional and transpressional structures Mesozoic and Hercynian faults Tectonic structures are essential for geopotentials! 7
