WebOct 3, 2024 · This paper presents the results of the electrical conductivity measurements of sand–clay mixtures that were formed of three types of sands and five pure clays and prepared with water of low salinity. The results show that an increase in clay content results in an increase in the overall electrical conductivity. Moreover, a direct or inverse … WebSep 12, 2024 · The electrical conductivity (mS/m) of a porous material is the combination of electrical conductivities of the matrix material and the pore fluid . Air, water, or saline water may be present in the pore. When the pore fluid is of low conductivity, for example, air or water, the bulk conductivity of clay mineral is contributed by the matrix ...
WebElectrical conductivity is one of the soil properties, which are associated with the nature of soil composition (i.e., particle ... porosity, and brine saturation of rocks. The application of Archie's law to clay soils is questionable because electrical conductivity is influenced by other parameters such as cation exchange capacity, specific ... WebFeb 1, 2024 · The apparent soil electrical conductivity and magnetic susceptibility were measured by electromagnetic induction with the a Geonics EM38-MK2 Ground Conductivity Meter at two depths: 0.5 and 1 m. For the vertical dipole orientation used during measurements, the effective depth is 1.5 m for a coil distance of 1.0 m and 0.75 m …
