Relation of SIP Relaxation Time of Sands to Salinity, Grain Size and Hydraulic Conductivity

P054 Relation of SIP relaxation time of sands to salinity grain size and hydraulic conductivity Abstract 1 The spectral induced polarisation (SIP) characteristics of sedimentary rocks contain structural information which potentially can be linked to flow and transport parameters such as hydraulic conductivity. We examined this connection for pure saturated sands by measuring SIP spectra of sands with different grain size and pore water electrical conductivity. For each spectrum relaxation times chargeabilities and Cole-Cole exponents were determined for identified dispersion ranges under the assumption of superimposed Cole-Cole model responses. We here focus on the results concerning the relaxation time of
