WebPore-Water Salinity: The induced polarization within a rock depends on having a mechanism for accumulating ionic charges. It also depends on the salinity of the pore water; i.e. the concentration of ions within the pore water. As the pore-water salinity increases, so does the capacity of the rock to support a build-up of ionic charges. floral patchwork dhurrie cushion world marketWebThe pore-microfracture structure, water-rock interaction and capillary water absorption mechanism of red-layer mudstone were comprehensively studied.
