"From the Preface: Diamonds and their source rocks have long been recognized in India where a fully fledged diamond industry flourished for nearly two hundred years during the medieval period. The industry gradually dwindled mainly due to depletion of easily accessible surface resources. Consequently, interest in the source rocks gradually diminished. Currently, India is not a world leader in diamond production and very little information on Indian diamond bearing rocks is available, although a few studies have been presented at International Kimberlite Conferences. In contrast, a significant amount of data have been published in Indian periodicals and government reports which are not easily accessible to geologists outside the subcontinent." The book is comprised of six chapters. The first gives a brief account of Indian geology, distribution of Kimberlites, Lamproites and lamprophyres in India, and the IUGS recognized definitions of these rocks. Chapters 2,3,4,5 and 6 provide information on diamonds, Kimberlites and related rocks occurring in the Dharwar, Aravalli-Bundelkhand and Bastar cratons, the Gondwana coalfield Lamproites and lamprophyres of the Northeastern region, respectively"--www.vedamsbooks.com/no107883/diamonds-their-source-rocks-india-fareeduddin-roger-h-mitchell.
