# Detection of Mineralization Zones Using Aeromagnetic Data
## 4 Results and Discussion
This technique was utilized to aid mineral exploration by detecting favorable zones, and only the positive traits were utilized in this case. Here, the boundary between ophiolitic rocks, sediments, and other rock units was cleared here. Noise and background signals were reduced using amplitude thresholding. The extracted linear features were then thinned using skeletonization. Finally, the skeleton, which included the linear features extracted, was transformed to lineaments, as indicated by the magnetic lineaments map (Figure 9). The proposed prospective areas are inferred from the rose diagram's defined patterns in the N-S, NW-SE, NNW-SSE, NNE-SSW, minor E-W, and NE-SW structures of the CET grid approach (Figure 9). Favorable zones include those where altered sediments are linked to basement rocks lithologically (Figure 9). Figure 7: The research area’s AS map. Figure 8: A map showing the research area’s TDR.

The structural complexity orientation entropy (OE) map was used to illustrate porphyry properties (Figure 10B). It depicts regions where structures appear in a variety of orientations; high-entropy regions are assumed to have a high level of statistical unpredictability, and thus a high level of structural complexity. The ophiolitic serpentinite, metagabbro, and ophioliitic basic metavolcanic rocks have most of these similar traits. The NE-SW and NW-SE directions are the favored orientations of these deposits, meaning that additional ore will be deposited in the investigated area.

The boundary tracing plugin is useful for outlining discovered porphyry-like features from the CET porphyry analysis. This plugin makes use of the output from the Central Peak Detection and Amplitude Contrast Transform plugins, which offer detected porphyry center locations and a halo-shaped ring around the porphyrins, respectively. The RTP and the OE maps (Figure 10A,B) were overlaid with the circular boundary tracing and vectorization lineaments. As can be seen, the study region contains many locations for porphyry mineral deposits, which are almost concentrated in the Barramiya gold mine area in the western part of the region, as well as large deposits delineated on the Barramiya Umm-Salatti belt in the northeast of the study region and extending in the NE-SW direction. However, the western part of the study area, which is represented by Abu Marwa and Abu Mireiwah, covers a large amount of porphyry deposits. The CET have a significant role in the detection of the potential location for mineralization where the favorable locations for deposition are determined on the entropy map (Figure 10B) and structurally controlled by the lineaments detected from the vectorization lineaments map (Figure 9). The results obtained by this technique are concordant with the geological studies conducted by many researchers on the area. In terms of geophysical techniques, aeromagnetic techniques, for example, are appropriate and effective in examining mineralized, alteration, and prospective zones [33; 34; 35; 36; 37; 38]. However, there are just a few publications that have been published that look at the relationship between magnetic intensity and gold mineralization zones (e.g., [16; 39; 40]. We used magnetic data and various techniques to determine the structural trends and/or shear zones that control and identify mineralization zones in this study. Lineaments are utilized in magnetic studies to indicate the main shear zones, fracturing, and faulting patterns so that we may learn more about the forces that have influenced the area in the past. The mine area is affected by lateral strike-slip faults [14].
