Geochemical Characteristic and Petrogenesis of Malumfashi Schist around Tandama Area, North-Western Nigeria
between designed the study, the statistical ABSTRACT Malumfashi schists which occur in association with migmatite-gneisses and biotite granite, occupy about 60% of Tandama area, north-western Nigeria. geochemical features like the Na 2 O/Al 2 O 3 values, trace element ratios such as Th/U and REE patterns suggest that the protolith are predominantly derived from felsic igneous sources. Tectonically, SiO 2 /Al 2 O 3 versus K 2 O/Na 2 O plot revealed the protolith to have evolved within passive margin environment.
