Abstract

Previous work between the University of Birmingham and Technical University Clausthal<br>examined the basic shape of the complex conductivity spectra of sandstones saturated with a synthetic<br>groundwater solution and compared the two different laboratory measurement procedures. It is known<br>that the Spectral Induced Polarisation (SIP) is also dependent upon the pore fluid so we examined the<br>effect of two different salinity groundwaters on the SIP response. The changes caused by decreasing the<br>salinity of the groundwater varied widely for different sandstones with both increasing and decreasing<br>phase angles recorded along with some changes in the shape of the spectra. We are now continuing to<br>make multiple salinity measurements with a variety of cations in order to better quantify these changes.
