An approach is presented to establish a state-wide basis for geochemical background values from the available data of Geological Survey Bavaria. For this purpose, typical element concentrations rock units in Bavaria were statistically evaluated and lithogeochemical map derived geological at scale 1:25,000. The elements comprise 39 geogenic main trace (SiO2, Al2O3, Fe2O3, MnO, MgO, CaO, Na2O, K2...
