or more of the individual data sets. Magnetic measurements proved to be the most useful geophysical tool for locating dikes in the area. Contacts between dikes and surrounding rock have been shown to be major water conduits, so the locations of dikes were as important as fault and fracture location. The combination of data sets proved valuable for corroborating the findings from any given data set. From the geophysical data, it appears that the western half of the survey area is more intensely fractured than the eastern half, although a few large lineations, presumably fractures or faults, appear in both areas. Ground follow-up in selected areas confirmed the reliability of the airborne data.
