Abstract

Abstract Transfer of geologic data and superimpositioning of Landsat imagery and digital airborne gamma ‐ ray spectrometric data was conducted to extract useful geologic information related to exploration targets and to detect geologic associations suitable for mineral emplacement. Three major plutonic bodies located in eastern Nova Scotia were selected as test sites to examine the utility of such a database in humid, heavily vegetated regions. The integration technique permitted the extraction of spectral relationships controlled by the existing geology of the region, detection of plutonic phases, and the delineation of lineament distribution. Exploration target areas were selected on the basis of the detection of above threshold values for the equivalent Uranium, equivalent Thorium ratio, as well as the intersection of lineaments and other geologic characteristics. These localities are suitable for mineral emplacement and warrant systematic field investigation including geologic, geophysical, and geochemical analysis.
