Review

Superb...Mitchell has clearly established himself as an authority in his field. He writes with admirable clarity and his mastery of the literature of this vast subject is both encylopaedic and discerning ... [This book] is an outstanding good contribution to petrology.' Geological Magazine

Synopsis

The final volume in a trilogy of monographs devoted to the petrology of primary diamond-bearing rocks. The principal objective is to present a revised terminology for primary diamond-bearing rocks. Much of the text is devoted to summarizing all that is known of the mineralogy and geochemistry of orangeites, incorporating several thousand new analys
