**4.2 Self-potential anomaly of manganese ore body**

**Figure 7** demonstrates a self-potential anomaly over a Weiss copper ore body in the Ergani copper district, Turkey [46]. The Weiss self-potential anomaly profile has a length of 144 m and digitized with an interval of 7.7 m. This anomaly has subjected to the three interpretation approaches as discussed earlier. Firstly, the interpreted results due to applying the least-squares approach are shown in **Table 7** for various s-values. Also, the applying of the Werner deconvolution approach, the interpretive results obtained are *z* = 36.9 m and *xo* = �2.1 m. Finally, the depth and the other model parameters evaluated by using the particle swarm approach are presented in **Table 8**.
