    Integrating geophysical signatures for delineating mineralized zones in Ikungi, Central Tanzania
    (The University of Dodoma, 2023) Matiku, Raymond P.
    This study presents the results of nine potential zones of mineralization in Ikungi, Manyoni Singida region. Integration of high-resolution geophysical signatures and geochemical data sampled from both active and abandoned pits have provided insights into the structural controls of mineralization and delineated the most potential mineralized zones in the study area. The geophysical signatures, which were obtained from magnetic, radiometric and VTEM datasets facilitated the understanding of structural controls such as faults and shear zones and identifying the most favourable location for gold mineralization. The results of the geophysical anomalies have delineated the subsurface structures, anomalous bodies, and lithological boundaries, which all play important control on gold mineralization. The geophysical anomaly results have delineated the presence of subsurface structures, which control the mineralization. These faults and shears structures are characterized by NW-SE, SW-NE and E-W trend direction. Furthermore, the geochemical laboratory analysis results have revealed high-gold concentrations from these structures, which supports the presence of significant mineral deposits in the area. Nine zones of mineralization are found in Granitic gneiss implying that the gneiss might have been affected by phases of metamorphism and deformations. The presence of active gold mines such as Shanta Gold Mine and Muhintili Artisanal Mine pits in the study area increases the likelihood of gold mineralization of the rest of the seven (7) potential zones in the study area.
