The study area covers Zaranda village and environs within Latitude 10° 16' 00" N, 10° 13' 00" N and longitude 9° 39' 21" E, 9°42' 35"E, on the northern pre-cambrian basement, the area comprises mainly of pan African migmatites, based on previous literatures. 15 samples of rocks have been subjected to geochemical and petrology studies after geological mapping technique. the rock samples are found to contain high amount of silicon oxides and low major oxides, Minerals identified are: Biotite, illimenite, silimanite, garnet, quartz feldspar (plagioclase orthoclase). microstructures observed under cross- and plane- polarised light, is an indication of rock forms as a result of partial melting the structures includes; melting of feldspar in quartz and vis -e- vis, and cleavages in plagioclase feldspar , the paleosome appears finer and lighter as observed on the field, it is found to be the remains of metasedimentary rocks as evident by quartzite rock is observed at a point within the study area, This work shows sodium rich plagioclase the work has successfully categorise the homogeneous and inhomogeneous migmatite in to metatexite, melanocratic and leucocratic diatexites.
Key words: Migmatites, Older ganite, Bauchi Anatectic Granite.
