Construction of basement depth map in al-Jezira Area Northwestern Iraq using two-dimensional spectral analysis technique

الملخص EN

A basement depth map can be considered as an aiding tool in deducing the structural and stratigraphical features existing in the sedimentary sections overlying basement rocks.

Sometimes, structures within the sedimentary cover that affected by basement relief were individually acquired it’s geometrical characteristics as a result of compaction occurred in sediments around hills or protrusions carved on an underlying basement, this may caused structural closures on overlying sedimentary formations.

In this paper, a basement depth map of Al-Jezira area north western Iraq is constructed from gravity data by applying two-dimensional spectral analysis technique.

The estimated basement depth values are ranging between (6) km in the northwestern part of the studied area to about (10.5) km in the eastern part of it.
