Abstract :
Field geological and petrographic characteristics of granitic rocks and their variants exposed at Devadurga town, Raichur district, Karnataka are described. The granitic rocks of Devadurga are part of younger ‘Closepet granite’ within a country of Peninsular Gneissic Complex (PGC) of Archaean age. Based on field and petrographic observations of this investigation, the younger granitic rocks of ‘Closepet granite’ within the study area can be sub-divided into leucogranite, grey porphyritic granite, pink granite, pink biotite granite, grey biotite granite, pink porphyritic granite. All these granitic variants possess more or less similar mineralogical assemblages and petrographic features such as myrmekitic, perthitic signifying their magmatic origin.
