Summary:

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 ora
