Rajasthan (Northwest India) is perhaps one of the very few regions in the world -- exhibiting, as it does, well-preserved records of an unbroken geological history of over 3,500 million years: from Middle Archaean to the present day. Marshalling the whole extent of available data, this volume vividly delineates the geological evolution of Rajasthan''s crust -- within the framework of modern concepts. The book embodies 300 illustrations, including line-drawings, photographs, and geological maps of key regions.
