Abstract

This study examines the use of remote sensing technology in geology to discover probable extensions of an iron ore deposits in the eastern part of Wadi Shati, Libya. Enhanced Thematic Mapper Plus (ETM+) data, registered in eight thematic bands in order to produce a false color image were used in this study. The eight bands were subjected to different methods of statistical analysis that resulted in choosing bands (7, 4 and 2) assigned to red, green and blue respectively. Landsat ETM images were geometrically corrected and the registered. Images were rectified according to geographic projection WGS. Radiometric correction was applied to remove the effects that alter the spectral characteristics of land features. Image processing techniques such as Maximum Likelihood supervised classification image for bands (7, 4, 2), band ratio images (5/7, 5/4, and 3/1), Intensity, Hue and Saturation (HIS) and data fusion of Landsat ETM+ image with Radar SAR ERS-2, were applied to Landsat ETM+ images to discriminate and delineate the lithological units; a few samples were collected from the promising new areas and analyzed by XRD and XRF techniques. New areas of iron ore occurrences were found along the south-eastern part of Wadi Shati iron ore belts. The finding of this new iron ore deposit may suggest that the iron ore deposits extend beyond the sand covered area. This study may improve the knowledge of the iron ore deposit distribution, locate new extended areas of iron ore and finally a new potential map of iron ore deposits that indicate a new area of iron occurrences can be produced.
