Basement Relief Maps for Central & Southern Iraq from Gravity and Magnetic Data

Basement surface relief map for central and southern Iraq is constructed from magnetic data. The estimated depth values are calculated by two dimensional spectral analysis techniques. The smooth depth map has general characteristics features that the depth values increased towards NE direction. The difference between the non smoothed and smoothed basement maps produce the surface relief features of the basement. Areas of high and low relief zones are defined and delineating uplifted blocks and troughs, making continuous features with lateral deviations as faults where they due to the various forces acted in the area. These zones probably influenced the sedimentary cover and created an accompanied various structural features and fault trends. The possibility of studying the main structures of the main oil fields, the river courses and marshes areas are also can be linked with low areas.
