This study integrates remotely sensed and fieldwork data around the Atmur-Makhasharaf ophiolite belt in the Nubian Desert, Northern Sudan. The region's harsh, arid, rugged terrain makes spaceborne data highly effective for updating geological mapping and mineral prospecting. The optical multispectral Landsat 8 OLI, Sentinel-2, ASTER, and microwave Sentinel-1 scenes, combined with satellite gravity data, were digitally processed. The fused Landsat 8 OLI/Sentinel-2 data, processed by Decorrelation Stretched (DS), Principal Component Analysis (PCA), and Band Ratio (BR) transformations, enable lithological unit discrimination. The Sentinel-1 and fused Landsat 8/Sentinel-1 data enhanced structural lineaments and geological boundaries. The W-E and SE-trending dismembered Atmur- Makhasharaf ophiolitic nappes are of Neoproterozoic age, composed of basal ultramafic tectonites (serpentinite.. View More»
