2080 | Geof%u00edsica Internacional (2026) 65-25.2.3. 3D Inverse ModelFor structural geological characterization, inversion was conducted on both potential datasets utilizing polygons (Ply1 and Ply2) that defined two areas of interest. The 3D models of the Magnetic Anomaly delimit distributions of different materials with their corresponding magnetic susceptibility value [SI] in both polygons (Figure 8).Conversely, the 3D model constructed from the Bouguer Anomaly and utilizing Polygon 1 demonstrates a density distribution with a standard reduction density of 2.67 g/cm3, which is conventionally employed for calculating the Bouguer Anomaly and serves as a reference in this instance, as established at the onset of the data inversion (Ayala & Rey, 2009). This indicates that the density variations within the model are assessed relative to this standard, regarded as the baseline of its measurement scale.The 3D model derived from Polygon 1 confirms the presence of highly dense bodies associated with granitic-monzonitic intrusions during the Laramide Orogeny (Figure 8. Isosurface 1), which, based on its value range, corresponds to acidic igneous rocks, metamorphic rocks, granite, and quartz. Mineralization is observable above and around these bodies (Figure 8. Isosurface 2), which, based on its value range, may be related to certain sulfides, igneous and sedimentary rocks (Table 3).Upon examining solely, the peak values of both 3D models (Figure 8), it is evident that the mineralization correlates with the presence of the highly dense bodies 1 and 2, and that seemingly interlinks both bodies, exhibiting a distinct directional distribution (NW-SE), potentially influenced by geological faults identified in the 2D maps (Figure 6).To enhance understanding of the distribution of magnetic susceptibility values and densities, four sections were created based on two profiles that intersect several boreholes in both carbonate and volcanic environments.Distribution of mineralization correlated with material with magnetic properties (Isosurface). Also included is the topographic map superimposed with both 3D models, illustrating the geographic position of the wells under investigation.Sections 1a and 1b (Figure 9) intersect with the Muhi well and extend towards the SPFM well, where the lowest susceptibility values (Figure 9. 1b) and Figure 10. 2b), around -0.00031 SI) align with those of calcite [CaCO3] (Table 3., M.S. Calcite = around -0.00001 SI). Conversely, the highest magnetic susceptibility values may be indicative of sulfide mineralization located within the transition zone of densities, suggesting the potential emplacement of the carbonate sequence by a granitic intrusion. This cavity is located near a surface body of low density, such as the Muhi, which may be associated with groundwater. A normal type of fault was detected near the Muhi well, indicated by alterations in terrain and a significant discrepancy in density. The HA well is located within a density transition zone; nonetheless, substantial mineralization is absent.Figure 7. Analytical Signal Map of the Residual Effect of the Magnetic Anomaly.
