Book Description
This is a book about the petrology of kimberlites. It is not about upper mantle xenoliths, diamonds, or prospecting for kimberlites. The object of the book is to provide a comprehensive survey and critique of the advances which have been made in kimberlite studies over the last twenty-five years. Kimberlites are rare rock types; however, their relative obscurity is overriden by their economic and petrological importance to a degree which is not shared with the commoner varieties of igneous rocks. Kimberlites are consequently of interest to a diverse group of earth scientists, ranging from isotope g~ochemists concerned with the evolution of the mantle, to volcanologists pondering the origins of diatremes, to exploration geologists seeking new occurrences of the diamondiferous varieties. A common factor essential to all of these activities is a thorough understanding of the characteristics of kimberlites. For the petrologist, kimberlites are exciting and challenging objects for study. Their petrographic diversity, complex mineralogy and geochemistry, and unusual style of intrusion provide endless opportunities for stimulating hypothesis and conjecture concerning their origin and evolution. Kimberlites are a part of a wide spectrum of continental intra-cratonic magmatism. Only by understanding all of the parts of this activity in detail may we make progress in our understanding of the whole.

Book Description
Developments in Petrology, 11B: Kimberlites, II: The Mantle and Crust-Mantle Relationships focuses on the formation, characteristics, and properties of kimberlites. The selection first offers information on silicate and oxide inclusions in diamonds and diamond eclogite and graphite eclogite xenoliths from Orapa, Botswana. The text also ponders on petrography, petrology, and geochemistry of xenoliths and megacrysts from the Geronimo Volcanic Field in Arizona and two-pyroxene megacrysts from South African kimberlites. The text elaborates on the nature of the upper-most mantle beneath Victoria, Australia as deduced from ultramafic xenoliths and depleted mantle rocks and metasomatically altered peridotite inclusions in tertiary basalts from the Hessian Depression. Topics include area and rocks of investigation, composition, abundance, and properties of metasomatically altered mantle, and petrography and mineralogy. The selection is a dependable source of information for readers interested in the formation, properties, and characteristics of kimberlites.

Book Description
In these days of information explosion and high-cost publishing, it is perhaps only reasonable for an author to convince the reading public that it is getting something worth reading. After all, intense research into the upper mantle over the past two decades has already resulted in a number of volumes on kim berlites and their xenoliths. So why yet another one? First, in this book I have concentrated on kimberlite as an individual rock-type and a sampler of the upper mantle, in the hope of complementing such monographs as Deep seated inclusions in kimberlites and the problem of the composition of the upper mantle by N. V. Sobolev and Geologie du Diamant by M. G. Bardet, which have concentrated more on specific aspects of kimberlite and upper mantle geology; as a result I have not attempted to describe diamond prospecting and mining and, although I have attempted to give some of the up-to-date views on xenolith petrology, the confines of space have not permitted me to explore the complexities of the upper mantle as deeply as has Sobolev. Second, the literature is vast and I have tried to pull together for the reader the wide range of views and infor mation presented both in the recent geological literature and in recent multi-author volumes such as the Proceedings Vol umes of the two International Conferences on Kimberlite held at Capetown in 1973 and Santa Fe in 1977.

Book Description
Volume 1 of this special issue of Lithos, dedicated to Roger Clement, presents papers describing the geology and emplacement of several of the recently discovered kimberlites in northern Canada in which diamond mines are now operating. Other papers are concerned with the petrography, age of emplacement, geochemistry and petrogenesis of kimberlites from Canada and other worldwide localities.
