“…Detection of such responses in field surveys is likely to be very difficult. Non conductive minerals also typically produce small SIP phase responses arising from ion migration within the electrical double layer (EDL) at the mineral water interface (typically <<10 mrad at frequencies <1000 Hz; Vaudelet et al, 2011;Zhang et al, 2012). In contrast, semiconductive minerals dispersed in a matrix of non conducting minerals, including natural authigenic minerals such as magnetite, secondary precipitates and metallic particles may give larger phase responses, typically of the order of several tens to hundreds of mrad Personna et al, 2008;Ntarlagiannis et al, 2010a).…”

Spectral induced polarization (SIP) phase anomalies in field surveys at contaminated sites have previously been shown to correlate with the occurrence of chemically reducing conditions and/or semiconductive minerals, but the reasons for this are not fully understood. We report a systematic laboratory investigation of the role of the semiconductive mineral magnetite and its interaction with redox-active versus redox-inactive ions in producing such phase anomalies. The SIP responses of quartz sand with 5% magnetite in solutions containing redox-inactive [Formula: see text] and [Formula: see text] versus redox-active [Formula: see text] were measured across the pH ranges corresponding to adsorption of these metals to magnetite. With redox inactive ions [Formula: see text] and [Formula: see text], SIP phase response showed no changes across the pH range 4–10, corresponding to their adsorption, showing [Formula: see text] anomalies peaking at [Formula: see text]–74 Hz. These large phase anomalies are probably caused by polarization of the magnetite-solution interfaces. With the redox-active ion [Formula: see text], frequency of peak phase response decreased progressively from [Formula: see text] to [Formula: see text] as effluent pH increased from four to seven, corresponding to progressive adsorption of [Formula: see text] to the magnetite surface. The latter frequency (3 Hz) corresponds approximately with those of phase anomalies detected in field surveys reported elsewhere. We conclude that pH sensitivity arises from redox reactions between [Formula: see text] and magnetite surfaces, with transfer of electrical charge through the bulk mineral, as reported in other laboratory investigations. Our results confirm that SIP measurements are sensitive to redox reactions involving charge transfers between adsorbed ions and semiconductive minerals. Phase anomalies seen in field surveys of groundwater contamination and biostimulation may therefore be indicative of iron-reducing conditions, when semiconductive iron minerals such as magnetite are present.

“…Two electrical conduction mechanisms are recognized as viable pathways in porous media: electrolytic conductivity (σ el ) occurs within the fluid in the interconnected pore volume and surface conductivity (σ surf *) which is the result of electrochemical polarization of the electrical double layer (EDL) at the grain fluid interface (Revil and Glover, 1998;Wu et al, 2008;Vaudelet et al, 2011). This polarization is frequency dependent and controlled by the surface chemical and microgeometrical properties of the sample (Knight and Endres, 1990).…”
