    Characteristics of graphite mineralization and it’s exploration potential in Chenjere area Ruangwa district south eastern Tanzania
    (The University of Dodma, 2021) Moye, Charles Daniel
    Electromagnetic and magnetic surveys, geological mapping, trenching, drilling and geochemical analysis were carried out in the Chenjere area to investigate the graphite characteristic and the exploration potential of graphite mineralization. Mtimbo, Matochi, Ng'imbwa, and Nakapelo were discovered to have graphite potential using these approaches. Loss on ignition (LOI) and infrared spectroscope (IR) analysis revealed graphite grades ranging from 4 to 8 wt.%. The graphite zones have thicknesses of 13 to 29 m and strike lengths of 1 to 4 km. The study has revealed that the graphite mineralization zones are concordant with the prominent strike of NE to SW. The electromagnetic signals have shown a positive correlation with the graphite mineralization as the high conducting bodies are coinciding with the graphite mineralization. This is proven by samples from trenching and drilling analysed by the IR method. Petrographic studies have confirmed that the graphite encountered is of flake type disseminated in the host rock of graphitic gneiss. Flakes showed dip-slip lineation similar to those of hosting rocks. Based on the field observation, electromagnetic survey, graphite grade, petrographic studies and comparison with the renowned graphite deposits the Chenjere graphite is of sedimentary origin. The graphite flakes are coarse ranging from 50 to 1000 µm. The lath shape flakes had inter growth with silicate gangue minerals with no overgrowth. The graphite flake size, the grade and the extension are warranting for the economic exploration potential in the Chenjere area
