| الملخص | The total count radiometric data of KirkukQuadrangle (the map area) was analyzed and separated to its residual and regional (background) maps. The regional maps showed an increase in radiometric background from southwest towards the northeast, while the residual radiometric anomaly map showed two residual radiometric anomalies distributed in the map area.
Anomaly (R1) is located in the southwest part of the map area, which comprises numerous, wide, elongated and isolated anomalies extended in NE–SW and NW–SE directions.The maximum residual radiation value of this anomaly is 275 c/s.This anomaly coincides mainly with Quaternary sediments (mostly with sheet run-off, slope sediments and valley fill sediments), Bai Hassan Formation, Mukdadiyah Formation, Injana Formation and Fatha Formation.
Anomalies (R2) is located in the northeast of the map area, which comprises numerous, wide, narrow, elongated, rounded and isolated anomalies extended in NW-SE direction parallel to the Kirkuk thrust fault , these anomalies coincide with Bai Hassan Formation, Mukdadiyah Formation, Injana Formation,Fatha Formation and Quaternary sediments(slope sediments).
A comparison between total count radiometric map and the geological map of the study area was carried out; it showed a radioactive range of each geologic formation and Quaternary sediments. It was concluded that, in general, the structural setting of the map area, which ischaracterized by existence of numerous surface and subsurface structures might play an important role in forming some radiometric anomalies of the map area. | |
