ABSTRACT

The quality of solid materials in rocks of Michika local government area of Adamawa state, was studied and the results of the chemical analysis shows that all the areas sampled are silicate rocks, because of their high silica contents ranging from 59.359+0.02% to 93.761+0.002%. Based on the silica content classification scheme all the sampled areas are felsic rocks except Futuless B that is intermediate rock with 59.359+0.02%, the results of the analysis indicates the presence of quartz, mica and feldspar. Most of the sampled areas contained appreciable value of Al₂O₃, Fe₂O₃, Na₂O and K₂O from the comparative analysis between rocks of these areas and similar rocks elsewhere shows that they compares favourably with respect to their chemical composition. Base on this analysis, the principal rocks commonly found in the sampled areas are granite and rhyohite.
