摘要：

Preliminary results of some model tank resistivity experiments with Wenner and surface laterolog arrangements are reported. The latter is the surface equivalent of a focused electrode system used by Doll (1951) for bore-hole investigations. The ore model is a sheet of finite conductivity with varying depths, dips and conductivity ratios. The surface laterolog has two advantages: (1) the shape of the anomaly is simpler and consists of one trough centered over the ore body and (2) the magnitude of the anomaly is considerably larger. It is thus more effective for deeper investigations. The Wenner system, however, provides a more direct measure for the thickness and the dip of the ore sheet. In addition, the field procedure and computations are simpler. © 1969.
