The Canadian Shield and adjacent areas underlain by cratonic rocks are a highly prospective geologic environment for diamonds. This volume reviews the genesis of diamonds and the petrology of kimberlites and lamproites, the major diamond-bearing rock types. It then describes diamond exploration techniques, focusing on the use of indicator minerals as a means of identifying prospective areas. Topics covered include major-element geochemistry of indicator minerals, eclogitic paragenesis, and trace element techniques. The volume also discusses the indicator mineral geochemistry results from a study of 18 localities around the world. In addition, since conventional indicator mineral techniques are not always applicable to lamproite exploration, alternative pathfinder minerals are reviewed.

Steep crystalline-basement faults, commonly indicated by potential-field anomalies, played a crucial role in evolution of continental cratonic platforms. In the Phanerozoic Western Canada Sedimentary Province, history of crustal block movements and warps is reconstructed from the distribution of depocenters, lithofacies and structures in structural-formational étages in sedimentary cover. Each étage is a rock succession formed during a particular tectonic stage; regional tectonic restructuring closes each stage, and the next stage represents a new tectonic regime. Practical tectonic analysis, based on observation of rocks and geophysical data, is a reliable guide for deciphering a region's geologic history and for resource exploration.

Diamond is the record-setter in many mineralogical properties such as hardness, diffusivity, thermal conductivity, purity, and covalency of bonding. Similarly, diamond, as the premier gemstone of the mantle holds primacy for geological features such as age and depth of origin. Diamond was among the first crystalline structures to be solved by X-ray diffraction and the first materials measured for their Raman spectrum. At more than 80 billion USD in yearly commercial value, diamond sets the record for the most traded, valuable mineral on the planet. Despite its chemical simplicity, diamond has been the object of more research effort, and had more scientific and popular press pages written about it, than any other mineral.

First published in 2001, Barren Lands is the classic true story of the men who sought—and found—a great diamond mine on the last frontier of the far north. From a bloody 18th-century trek across the Canadian tundra to the daunting natural forces facing protagonists Chuck Fipke and Stewart Blusson as they struggle against the mighty DeBeers cartel, this is the definitive account of one of the world’s great mineral discoveries. Combining geology, science history, raw nature, and high intrigue, it is also a tale of supreme adventure, taking the reader into a magical—and now fast-vanishing—wild landscape. Now in a newly revised and updated edition.

Diamonds in Nature: A Guide to Rough Diamonds illustrates the range of crystal shapes, colours, surface textures, and mineral inclusions of rough, uncut, naturally forming diamonds. Each chapter contains photographs that show the unique physical characteristics of the diamonds, and the accompanying text describes the processes that led to their formation. This book is an invaluable reference manual for professional geoscientists—including gemmologists and exploration geologists.
