Integrated Studies Intrigue to Mineral Prospectivity. Applicability to Kikombo, Dodoma, Tanzania.

Detailed prospecting studies were carried out in Kikombo, Dodoma, Central Tanzania to examine the possible mineralization zones through delineating subsurface structures and characterizing geochemical distribution of various elements by integrating the results of the methods applied. The prospecting methods utilized include geological methods, regional aeromagnetic survey, local ground magnetic survey, airborne gravity survey, induced polarization survey and geochemical survey. Geological observation shows the area’s underneath geology to be composed of tonalitic — orthogneiss rock types whose regolith is composed of brown sand which is light as well as reddish. Gravity survey results suggest high gravity anomaly to most of the occupied area. Aeromagnetic surveys reveal high magnetic anomaly to most of the occupied area with NE-SW structural trending patterns. Local ground magnetic survey reveals to lack prominent structures (faults) that are deep and localized, however, the shallow structures were revealed showing similar trend of NE -SW. The depth to the magnetic anomaly of various methods employed goes up to 494.1 m. IP results indicate high resistive and chargeable bodies at the basement with some faults striking NE-SW. Geochemical survey shows the concentration of elements such as As, Au, Ca, Cr, Cu, Fe, K, Mg, Mn, P, S, Ti, V, Zn and Zr while suggesting a strong positive correlation of Mn and Cu.
