| Abstract | ||
| The concealed geology and structures of southern part of Iraq has been investigated by analyzing the gravity fields. The main structural and tectonic trends are clearly defined in the N – S and NW – SE directions through using Fan Filtering technique. Deep regional geological trends represent basement features, while shallow structural trends are confined to structures in the sedimentary rocks. The deep trends act as zones of weakness that affected the sedimentary cover through the different phases of the Alpine Orogeny and led to create different types of N – S and NW – SE folded shallow structures. The obtained structural trends indicate the possibility of N – S and NW – SE distribution, of the geological features all over the central and southern part of Iraq and they add new information concerning deep geologic structures. | ||
