Abstract
Remote sensing techniques provide meaningful information to mineral exploration by identifying the hydrothermally altered minerals and the fracture/fault systems. In this irticle, Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) data were processed to detect the hydrothermal alteration zones in Hamama area in the central part of the Eastern Desert of Egypt. Band ratios and principal component analyses uccessfully revealed he extent and the geometry of the hydrothermal alteration zones that trend in an NE-SW direction. Matching pixel spectrum derived from Minimum Noise Fraction, Pixel Purity Index, and n-dimensional visualization wIth reference spectra allowed characterizing key hydrothermal alteration minerals, including chlorite, kaolinite-smectite, muscovite, and haematite, in successive alteration pattern. cield investigations ind X-Ray Diffraction analysis validated hne results revealed by ASTER data. In addition, the present prospects of significant gold and massive sulphide_ mineralizations are consistent with the detected hydrothermal alteration zone.
