Abstract

Abstract

The 2-D inversion is the best method in the interpretation of DC resistivity sounding profiles data owing to its high speed, but the 3-D inversion, by contrast, needs more measured data and more computer time. Through the 2-D inversional study of several 3-D models, we know that for the good conductor ore-body without strike, there is some deflection between the center of real ore-body and the center of anomaly enclosed by the 2-D inversion, however, the anomaly can still reflect the true shape and the center position of the ore-body in the main. When the ore-body has certain lengths in strike, the effect of 2-D inversion is good to it, no matter its resistivity is high or low.
