The study was conducted on exposed rocks of Zaranda village of Bauchi state in Nigeria, which falls within latitudes 10°16'00" N & 10°13'00"N and longitudes 9°39'21"E & 9°42'35"E. Previous studies have identified the rocks as metatext, leucocratic & mesocratic, these rocks compose of quartz biotite, plagioclase, microcline, and garnet which are results of fractional crystallization and partial melting in some areas, this two mechanism of differentiation are both capable of segregating minerals, This research work uses trace elements and rare earth elements, previous literature, rock features, mode of rock emplacement, structures & minerals found in rock to determine whether or not economic mineralization has taken place during the metamorphism/crystallization of the rocks of the study area. Rock samples are generally low laying out crops, Geochemical data were analysed, and interpretation indicates rock samples are A-type granite, in peraluminus, calcic, and are emplaced by volcanic arc & syn-collitional. The research work concludes that the quartzite sample (S1) contains Gold, However, no fracture is observed on the rock sample compared to elsewhere where gold mining is taking place, sample metatexite S24 appears as anomalous granite while in addition has the same mineralogical composition as mineralised granite field of New England, with leucocratic sample number S3, S22, & 215, mesocratic S20, metatexite S16 The three microstructures myrmekite, perthite & antipatithe observed on the rock samples are not related to any mineralisation.
