Spectral induced polarization of Na-montmorillonite dispersions.
Montmorillonite (Mt) clays have a high specific surface area and surface charge, which confer them remarkable adsorption properties. Nevertheless, their electrochemical and aggregation behavior are not completely elucidated because of the complexity of their microstructural and interfacial properties. In this work, the conductive and dispersive properties of Na-Mt suspensions of weight fraction...
متن کاملUsing a combination of genetic algorithm and particle swarm optimization algorithm for GEMTIP modeling of spectral-induced polarization data
The generalized effective-medium theory of induced polarization (GEMTIP) is a newly developed relaxation model that incorporates the petro-physical and structural characteristics of polarizable rocks in the grain/porous scale to model their complex resistivity/conductivity spectra. The inversion of the GEMTIP relaxation model parameter from spectral-induced polarization data is a challenging is...
متن کاملApparent resistivity and spectral induced polarization in the submarine environment
Relatively few investigations have employed electrical methods in the submarine environment, which may be promising for mineral deposits or threatened by environmental problems. We have measured the electric field using both disk and bar electrodes in the sea water at three different levels: sea surface, seven meters deep, and sea bottom at a depth of ten meters, employing a 2 m spacing dipole-...
متن کاملEstimation of Chargeability and Permeability using Spectral Induced Polarization Data
Induced polarization (IP) method has been successfully implemented in investigation of groundwater, geothermal and metallic ores. From published (Nordsiek and Weller, 2008) spectral induced polarization (SIP) data, the amplitude and phase spectra have been derived. Frequencydependent impedance data sets have been calculated from these SIP data sets, which were derived for chargeability by Debye...
متن کاملSpectral Induced Polarization Measurements on Unsaturated, Unconsolidated Sediments
Understanding the Spectral Induced Polarization (SIP) response to saturation is required to improve application of this geophysical technique in the vadose zone. SIP measurements (0.11000 Hz) were conducted on three unconsolidated sediments during evaporative drying. Sample grain size distribution was determined from laser particle size diffraction measurements. The dependence of the real and i...
