Resistivity Profiling – Banded Iron Formation – South Dakota

Two-dimensional resistivity profiling of geological media to distinguish structure and stratigraphy. The example shows different sized targets at different depths and their relative resolution. One of the great advantages of this type of geophysical survey is the nonintrusive nature of the methodology. In the example below all data were acquired from the surface, and a significant amount of detail is realized before any drilling commences.
