Use Of Square Array Resistivity To Assess The Style Of Jointing On The Palisades Cliffs, Northern New Jersey

The square electrode array has been shown to be particularly sensitive to anisotropy in<br>the subsurface (Habberjam, 1972); however, little work has been published which uses it (Lane,<br>et al., 1995). We discuss a study which has used both the square array and the Wenner array for<br>determining joint patterns on the Palisades Cliffs, which overlook the Hudson River on its west<br>side between Hoboken, New Jersey, and Nyack, New York. These joint patterns are of interest,<br>because rockfalls from the cliffs are common and pose a significant hazard to a road which runs<br>along their base.
