### Aeromagnetic & Airborne Gravity Interpretation
#### 5.1.1 Aeromagnetic Interpretation
Red arrows are pointing to the structural trends that are more prominent in either TMI_RTE data and rectangle in (**E**) is highlighting the complex faults within the low magnetic zone in the south of the area. An evaluation of the Analytical Signal (AS) (Figure 7) maps confirms the presence of E-W oriented magnetic bodies in the southern section of the survey area, with local variations of elongated geological bodies with high magnetic anomalies. The residual AS magnetic map at a wavelength less than 20 km shows a distinct E-W structural trend while WNW-ESE to E-W trends are seen on the residual map for wavelength less than 50 km. Overall, the magnetic data preserve a dominant E-W trend (Figure 7) and minor features oriented in NW-SE and NE-SW (Table 2). It can be assumed that a large E-W oriented magnetic bodies may be controlling the crystalline basement of Central Luconia with the major magnetic signal caused by the differences in the composition or changes of the sources of the geological bodies.

(**B**) The interpretation of structural trend based on (**A**). (**C**) Rose plot diagram for interpreted structural trend in (**B**), showing NW-SE, E-W and NE-SW orientations. (**D**) Analytical signal (Regional) for >50 km wavelength. (**E**) The interpretation of structural trend based on (**D**).
