ABSTRACT
 
The study area is located in Kirkuk governorate in the north–eastern part of Iraq within
the footills zone which includes the transverse Kirkuk block that contains oilfield anticlines
(Baba, Bai Hassan and Khabaz) trending NW to SE. The previous studies have pointed out
that there are tectonic faults and sub-blocks in and around the study area.
The enhancement processings were applied on the available geophysical data in the
purpose of identifying the tectonic and structural implications via a correlation with the
previous petroleum and academic studies. The first directional derivatives of the gravity data
revealed the presence of three deep seated secondary blocks coinciding with the boundary of
central faulting and Kirkuk fault. The map of the math's difference between the maps
obtained by filters (8 & 90) delineated the sub-blocks boundaries. Furthermore, the math's
difference between the maps obtained by filter (8) and the original Bouguer is characterized
by associating with faults of south eastern parts of the study area. The map of math's
difference between geogridding and local polynomial data is also displayed that the
structures of Bai Hassan, Khabaz and Jambur representing a huge geological structure
(separated with saddles) parallel to Kirkuk structure.
The first directional derivative map of the geomagnetic data is also illustrated the
deep sub-blocks underneath the structures of the study area. As well, the map of the math's
difference between original total magnetic field and local polynomial is displayed the
presence of shallow magnetized bodies.
