Electrical conductivity of minerals and rocks

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).
