It is normally understood that the granite rocks represent the original crystal rocks of the earth’s lithosphere. During the cooling of magma the formation of granite rocks takes place towards the end of the differentiation of magma. The Presence of quartz, orthoclase feldspar and muscovite mica are indicative of the formation of granite and allied rocks as the Bowen’s reaction series developed during the last phase in the magma chamber. Because of lower specific gravity, although the granite rocks are generated as last units of magma cooling but occupy the topmost position and form the crust of the earth. During the geologic periods after the formation of the crust the granites have also been subjected to many tectonic activities and orogenic activities which have brought many changes in the original mineral composition ,texture and structure and therefore in their appearance and properties. These modified, altered or metamorphosed members of the granite family have developed stress minerals , shown presence of second generation minerals, crushing, pulverization and alteration including assimilation resulting in hybrid verities .This paper envisages to present some of these features which were found during the optical study of granites at different places of Jabalpur city.
