| dc.description | Many geophysical methods have been ,tried in the exploration for geothermally "hot" areas in the upper regions of the earth's crust. The only method that has been cbnsistently found to be succes sful has been the resistivity technique. In this geophysical method, the specific resistivity (or its reciprocal, the specific conductivity) of the earth's subsurface is measured during traverses over the surface. The principle of the technique is bas ed on the fact that the resistivity of solution-saturated rocks will decrease as the salinity of the solutions is increased and! or the temperature of the system is increased (see _Figure 1). I Therefore, volumes of the earth's crust that contain abnormally hot and saline solutions can often be detected as regions of low resistivity. | |
