    Petrographic and geochemical analysis of basement rocks in Federal University Gusau and its environs, Zamfara State, Northwestern Nigeria were carried out in order to unveil the major rock forming minerals as well as the textural relationships composition within the rock. The identified rock unit is granite and they are mainly whitishgrey in colour, with the majority of them having porphyritic-coarse-grained texture and minor with fine-grained texture. The light coloured crystals in hand specimens are the felsic minerals mainly quartz, and feldspars while the grey-dark crystals are the mafic minerals like the biotite-mica. The result of the thin section analysis depicts that the minerals present within the rock samples in the area: quartz (40%), orthoclase (40%) and biotite (20%). These identified minerals are classified as the major rock forming silicate minerals. The geochemical ana.. Read More»
