    2020-1-7  electrical conductivity in typical minerals is usually due to some “impurities” such as ferric iron and hydrogen (Fig. 2). The electrical conductivity in iron-bearing minerals can still be “intrinsic”, i.e., conductivity could occur by the formation of a pair of electrons and holes through reaction (5).

    The rocks may be classified as Archie rocks or Non-Archie rocks, depending on the link between pore structure and resistivity of the rock. For carbonate rocks, keeping this factor in view, the applicability of Archie's law tends to be unreasonable and employing Archie's equation will ultimately lead to inaccurate estimates of the water saturation.
