Development and Testing of New Square-Array Resistivity Sounding Method

As part of OGW BG geophysical site characterization research through the USGS Toxic Substances Hydrology Program in 2000-2001, modified square-array resistivity sounding experiments were conducted at the Mirror Lake fractured rock research site in Hubbard Brook Experimental Forest, New Hampshire.

A newly developed azimuthal resisitivity sounding method was tested at the Mirror Lake fractured-rock field site. The new array should make it possible to discriminate between azimuthal resisitivity changes induced by steeply dipping sets of fractures and resistivity changes induced by a dipping bedrock surface or lateral resistivity changes.
