Petrophysic and mineralogical characterization of a perialpine gravel aquifer using geophysical logging methods. Kappelen test Site, Switzerland

Applied to the Kappelen test site, electric and nuclear logging methods permit to determine petrophysic characteristics of the formation of saturated gravels: total porosity and density. The estimation of matrix densityvalues starting from these parameters led to the determination of dominating mineral contents in the solid phase. The obtained petrophysic and mineralogical information can be used to understainding to hydraulic behaviours and paleogegraphical history
