The book satisfies the need of a text book of a very simple outline in which causes and their consequences are knit together as closely as possible a need long felt the author in his teaching and perhaps by other teachers also. The author has ventured therefore to depart from the common usage which subdivides geology into a number of departments. The plan of the book with its use of problems and treatment of land forms and rock structure in immediate connection with the processes which produce them was thought of keeping graduate and undergraduate courses in mind.
The book is divided clearly into three sections to address external geological agencies like rocks waters deposits erosions glaciers deep seas and sea shores as well as Internal geological agencies like Movements and disturbances within earth metamorphism and mineral veins with elements of historical geology. The historical geology part deals with geological records their formation and study traveling through various ages eras and periods starting from Pre-Cambrian systems to the quaternary. Lastly the book addresses the Geology of India including plate Tectonics Tectonic Evolution major rock groups Precambrian super-eon Phanerozoic Palaeozoic Mesozoic Cenozoic. The Indian plate, Gondwana breakup of Gondawana. Earthquake Hazard zoning in India.
