Khor Eit area is exposed geological units located at about 70 km north of Port-Sudan town along the Red Sea coast of Sudan, it may implement very important role for understanding the rifting process. The overall objective of this study is to investigate the rifting phases and their evidences considering the geological and the structural setting. The methods of investigation include; the satellite imageries of Landsat 8 OLI and Sentinel radar images had been directed to identify different lithological units and the major structural patterns. The geological mapping was conducted in helps of remote sensing data and field survey. Structural documentations were conducted during the field survey to identify the important structural elements. The obtained satellite gravity data was processed and manipulated to investigate subsurface geology. In this investigation, Bouguer gravity Anomalies (BA) and the Second Vertical Derivatives (SVD) were conducted for to detect rock density variations and structural alignments. The study concludes that the rifting firstly started with N-S fractures in Maghersum, Khor Eit and Abu Imama formations. The second phase is the subsidence phase after the deposition of Dungonab and upper clastic sediments formations that made the paleo-channel direction change toward the sea.
