Mining Potential of the Upper Cheliff Area (North of Algeria): Gravimetric and Magnetic Evidences

Located in the North of Algeria, the Upper Cheliff region boasts significant mineral potential, particularly in iron resources. Several studies have been conducted in the Upper Cheliff region, revealing the existence of multiple mineralized occurrences. In the context of mining, we utilized gravimetric and aeromagnetic data to study the subsurface characteristics of the Upper Cheliff region. By examining these data sets, valuable information can be gleaned regarding the mining prospects within the area. The processing of gravity and magnetic anomalies data reveals complex information, pinpointing the areas with varying densities and magnetic susceptibilities in Upper Cheliff. The mining indexes are discovered within the positive gravity anomalies and maxima analytic signal magnetic anomalies. The geophysical observations suggest that the mineralization is carried by dense and fractured structures. Based on this image, we interpret the other positive anomalies and maxima analytic signal magnetic anomalies identified in the Upper Cheliff as the continuity of these heavy structures, which do not reach the surface.
