Lithological structures

Unlike traditional methods, the ZZ Universal 61 channel resistivity meter shows true resistivity at a true location, so that geological features can be seen directly without further interpretation. The following profile shows smooth resistivity contours with the Russo Beds being resistive, and the silcrete horizon being highly resistive especially at its thickest part. Weathered, leached, and bleached Bulldog Shale is clearly contained within a moderate to high resistive zone (orange), while the underlying and less weathered Bulldog Shale is confined to the low resistivity zone (green and blue).
