The quadripole mapping method is a surface based direct current exploration technique to investigate the subsurface resistivity structure. Two orthogonal bipole sources are used. The electric field intensity and azimuth due to each bipole source is measured and by adding the two electric field vectors in various combinations, the apparent resistivity and conductance can be calculated as a function of the direction of the resultant electric field vector at each of the receiver stations. The result is a resistivity ellipse for which only three parameters are needed to define it. This technique was applied to several types of the theoretical models in order to understand and better interpret the field data. The quadripole mapping method was used in the vicinity of Hualapai Flat to study the subsurface geology and evaluate the geothermal prospect in Hualapai.
