The Nuweibi intrusion was emplaced during the final tectono-magmatic stage of Arabian-Nubian Shield development (ANS). Two cogenetic phases can be recognized in field: early phase is represented by porphyritic albite granite and non-porphyritic granite. Mineralogically, both are essentially composed albite, quartz, K-feldspars with subordinate muscovite. Accessory minerals include fluorite, zir...

Abstract The integration of remote sensing, spectral measurements and field verification helped in discriminating new iron occurrences hosted the metavolcanic rocks at Wadi Karim Gabal El-Hadid areas Central Eastern Desert (CED) Egypt. host were carefully recognized through different image processing techniques that applied on Landsat-8 satellite data with implementation signatures various mine...

Utilization of the digital Landsat TM bands for automatic lineaments extraction and selection of the optimum bands are the main objects of this article. The classical method for lineament extraction was manually performed through aerial photographs and satellite imagery. Nowadays several commercial softwares are developed to deal with the automatic linear features extraction using the optical a...

The existence of radioactivity linked to the heavy-bearing minerals in building materials—such as granite—has increased attention extraction procedure. Granite rocks play an essential economic role various areas Egypt. Thus, this study intended detect 238U, 232Th, and 40K activity concentrations examined granite samples determine corresponding radiological risks associated with granite. studied...
