Overview






This course is a basic to advanceintroductionfortheundergraduatestudentspursuing B.Sc. Geology / Engineering Graduate for Civil and Mining.The term petrology comes from the ancient GreekwordPetra “rock” and Logos “explanation”thatmeans the study of rocks and theirprocessesof origin.This coursedeals with the naturally occurringrocksin fieldas well aslaboratory analysisdatathat providesufficient information how they occur in the nature. It gives idea of modern petrological theories which are widely accepted for their origin.Thecoursedefinitelyprovides better understanding to students for the processes and principles involvedduring theoriginand evolutionof the rocks
