Abstract
The 85 papers contained in this two-volume set and reprinted from the journal Lithos were presented at the 8th International Kimberlite Conference in Victoria, British Columbia, Canada, in June 2003. They represent the most current published compendium of knowledge regarding the wide range of topics that the study of diamonds includes. Those economic geologists wishing to learn about the current state of knowledge in the diamond industry and in exploration for kimberlites will be compelled to read these papers, which cover subjects related to diamond growth, grade assessment, exploration methods, kimberlite petrogenesis, emplacement mechanisms, geochronology, mantle geochemistry, tectonics, and geometallurgy. Examples given are from Australia, Botswana, Brazil, Canada, China, Finland, India, Namibia, Russia, South Africa, Tanzania, USA, Venezuela, West Africa, and Zimbabwe, and from the deep mantle to the crust and the laboratory. These volumes address the interests of the mineral deposit and exploration community by providing the details of diamond formation, emplacement, exploration, and recovery, and then some. In exploration, target selection begins with analysis of craton architecture, regional geological terrain characteristics, prospectivity for kimberlite emplacement, and the potential for geologic diamond-producing or diamond-destructive factors at depth or at the surface. Techniques for indicator mineral analysis and diamond grade assessment, stone color, shape, and resorption characteristics, and resource estimation and geometallurgical factors all influence the viability of a project. Economic geologists will be interested to learn that the diamond business encompasses geology from the earth’s core (ultradeep diamonds) …
