| Abstract | ||||
| Remote sensing datasets have offered amazing breakthroughs in mapping rock units, structural components, and hydrothermal alteration zones. The main objective of this study is to distinguish the lithological elements of Ras Abdah Abu-Hadedah area, Northeastern Desert (NED), Egypt. This study used a multispectral dataset from Landsat-8. Image processing technologies include False Colour Combination (FCC) and Band Ratio (BR) were applied for lithological and alteration mapping. Lineament extraction is done using PCI Geomatica's commonly used LINE module. In addition, the correlation between hydrothermally-altered zones and structural characteristics highlights the need for additional investigation of ore deposits in the research region. These lineaments features are extracted using a panchromatic 15m pixel band. An image processing results provided updated geologic map to the study area. The dominated structural trends are presented in the area by NW-SE and NE-SW trends. This also demonstrates the effectiveness of the data and methods used. | ||||
