摘      要：Mineral deposit mapping is very essential for sustainable and eco-friendly exploitation of natural *** Kingdom of Saudi Arabia has abundant natural resources such as natural gas,oil and *** reserves high quantity of minerals such as phosphates,bauxites,copper,gold and other industrial *** red soil regions located in Hail and Qassim provinces of Saudi Arabia have rich amount of bauxite(major aluminum ore)*** order to initiate the focus on mapping of mineral deposits along this area,standardized hyper-spectral analysis has been carried out by using Advanced Spaceborne Thermal Emission and Reflection Radiometer(ASTER)satellite *** spectral signature of gibbsite(major element in bauxite)samples is analyzed with reference to the spectral features of gibbsite in the visible near infrared and short-wave infrared bands electromagnetic *** hyper-spectral transformations such as minimum noise fraction function and pixel purity index have been performed to identify the target *** existence of the mineral is confirmed by comparing the spectral signatures of the endmember with the predefined spectral plots of ASTER and United States Geological Survey spectral ***,the end-members are mapped and their abundance is estimated in 0–1 *** study has opened up new areas for mapping of bauxite deposits in the area and leads to eco-friendly exploitation of natural *** also validates the high potential of ASTER multispectral satellite data for the exploration and mapping of mineral resources.
