Abstract

Graphical abstract: Abstract: A gravity and magnetic analysis was performed over the Western Desert (WD) of Iraq to determine the structural makeup of the Phanerozoic sediments that overlie Precambrian lithologies. The WD contains a series of basins that were formed during a series of Precambrian to Paleozoic compressional tectonic events. Regional and residual gravity and magnetic anomaly maps created by a variety of methods, and a CET lineament analyzes of these maps indicate that the basins were formed mainly by strike-slip and transverse faults. These faults may have been the reactivation of faults formed during Precambrian compressional tectonic events. The prominent Nukhaib graben was found to be a series of smaller grabens and horsts whose origin is probably related to reactivation of Precambrian faults.
