Geology and Economic Potentials of Migmatite Around Filin Shagari, Kafin Madaki (SHEET 129 NW & SW) Bauchi N.E, Nigeria

Abstract

The rocks in the study area were carefully mapped and studied to understand their relationships, geological setting, distribution, structures in order to harness their economic potentials. The area is located within Pan African Older Granite in the Northwestern region of Ganjuwa L.G.A. in Bauchi state and is accessible through Bauchi-Ningi Road about 15km off from Federal High way. Adopting the Sawyer classification of migmatite, the rocks within the research area have few morphologies predominantly the Banded orthogneiss, Diatexites, massive Pegmatite ridges, and pocket of Nebulite. Morphological changes in the rocks were critically observed due to partial melting rate and possible deformation due to shear stress which possibly acted on the banded orthogneiss that was tilted vertically. Geochemical analyses from XRF and studies indicate that the presence high concentration of Al2O3 and SiO2 indicating a possible metasedimentary source and with further analysis to ascertained the economic potentials of the rocks AAS was also conducted on some selected samples that indicated some signals of lithium mineralization. And from the field observation hydrothermal fluid tend to be occupying the foliation planes of these banded orthogneiss to form mineralization.
