Abstract
With an objective to evaluate effects of clayish minerals in the electric and electromagnetic exploration methods, resistivities were measured on samples which have adjusted contents of clayish minerals. Samples were prepared for an experiment by mixing 300 g of glass beads having a diameter of about 1 mm, 200 g of aqueous solutions, and 3 to 90 g of smectites. The aqueous solutions used KCL, NaCL and CaCL2 at concentrations of 0.1 to 0.001 mol/L. The result of the experiment may be summarized as follows: among the three kinds of smectites, KN-1 has the greatest effect to reduce the resistivity; the resistivity decreases when the smectite amount is increased except when the concentration of the solution is high; this phenomenon is thought to be caused by increase in the region of an electrically doubled layer which has higher ion concentration; change in the resistivity increases when the solution concentration is low, and decreases when the concentration is high; and in the case of the solution concentration being 0.1 mol/L, the resistivity increases with increase in the smectite content. 5 refs., 7 figs., 1 tab.
