Fig. 15From: A laboratory approach for the calibration of seismic data in the western part of the Swiss Molasse Basin: the case history of well Humilly-2 (France) in the Geneva areaGrain density versus the compressional and shear seismic velocity with lines of constant acoustic impedance. Reflection coefficients values are reported between the acoustic impedance contours. All seismic velocities have been calculated at borehole conditions.
