Gold exploration by remote sensing techniques in the Wadi El Allaqi area, Egypt

Abstract

The Wadi El Allaqi area is the site of ancient and intermittent, recent activity in gold exploration and mining. The present work examines the application of remote sensing techniques to gold exploration under the natural conditions prevailing in this area. The geologic-lithologic units in the Wadi El Allaqi area have influenced the deposition of gold mineralizations. Rock units over 600 million years old act as hosts to the gold. Aerial photographs on a scale of 1:20,000 have been interpreted to delineate geologic-lithologic units, structural lineaments, and drainage and geomorphology. The results are compared with interpretations of Landsat imagery.
