Geological investigations are usually made by a number of techniques. The purpose of present work was to explore the chemical composition of the samples under study and also to see the reliability of the different instrumental techniques used for rock and mineral analysis. Chemical tests were performed prior to the use of any other technique in order to determine the nature of these rocks. The chemical analysis indicated the silica dominance in the rock composition, hence the acidic nature of the rock. The major, minor and trace elements were determined by employing X-ray fluorescence and atomic adsorption spectroscopic methods.
