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.

使用重力和航磁数据来定义伊拉克西部沙漠的结构配置

摘要 对伊拉克西部沙漠 (WD) 进行了重力和磁力分析，以确定覆盖前寒武纪岩性的显生宙沉积物的结构组成。WD 包含一系列盆地，这些盆地是在一系列前寒武纪至古生代挤压构造事件期间形成的。通过多种方法绘制的区域和剩余重磁异常图以及对这些图的 CET 线性分析表明，盆地主要由走滑和横向断层形成。这些断层可能是前寒武纪挤压构造事件期间形成的断层的重新激活。发现突出的 Nukhaib 地堑是一系列较小的地堑和地堑，其起源可能与前寒武纪断层的重新活动有关。
