ABSTRACT
The objective of this work is to show the
contribution of multispectral remote sensing data to detect and distinguish the
ophiolite rocks of Bi’r Umq and their geologic setting, southeast of Al Madinah
Al Munawarrah in Saudi Arabia. This work includes detailed fieldwork lab
studies, as well as processing operations, were performed on The Advanced Spaceborne Thermal
Emission and Reflection Radiometer (ASTER 2006, 2007) and Satellite Pour L’Observation
de la Terre SPOT 5 (2005) images of the study region. Among the processing techniques applied are band ratio, histogram stretching, the combination of spectral bands, image fusion. The techniques used
permitted a clearly show that the ultramafic rocks are distinct from other rock
units and contain important economic minerals. This research also illustrates the
tectonic parameters and that the remains of the oceanic crust are exposed and
juxtaposed to the rocks of the continental crust of the Arabian Shield. The
results of the spatial data processing revealed a good positive concordance
with the results of the field investigations.
