Download or read book Diamond Genesis Mineralogy and Geochemistry written by Karen Smit and published by Walter de Gruyter GmbH & Co KG. This book was released on 2023-05-03 with total page 898 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: This is the only book to focus on the geomorphological landscapes of Canada West. It outlines the little-appreciated diversity of Canada’s landscapes, and the nature of the geomorphological landscape, which deserves wider publicity. Three of the most important geomorphological facts related to Canada are that 90% of its total area emerged from ice-sheet cover relatively recently, from a geological perspective; permafrost underlies 50% of its landmass and the country enjoys the benefits of having three oceans as its borders: the Arctic, Pacific and Atlantic oceans. Canada West is a land of extreme contrasts — from the rugged Cordillera to the wide open spaces of the Prairies; from the humid west-coast forests to the semi-desert in the interior of British Columbia and from the vast Mackenzie river system of the to small, steep, cascading streams on Vancouver Island. The thickest Canadian permafrost is found in the Yukon and extensive areas of the Cordillera are underlain by sporadic permafrost side-by-side with the never-glaciated plateaus of the Yukon. One of the curiosities of Canada West is the presence of volcanic landforms, extruded through the ice cover of the late Pleistocene and Holocene epochs, which have also left a strong imprint on the landscape. The Mackenzie and Fraser deltas provide the contrast of large river deltas, debouching respectively into the Arctic and Pacific oceans.

Download or read book Mining Country written by John Sandlos and published by James Lorimer & Company. This book was released on 2021-09-07 with total page 226 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mining has had a significant presence in every part of Canada — from the east to west coasts to the far north. This book tells the stories of those who built Canada’s mining industry. It highlights the experiences of the people who lived and worked in mining towns across the country, the rise of major mining companies, and the emergence of Toronto and Vancouver as centres of global mining finance. It also addresses the devastating effects mining has had on Indigenous communities and their land and documents several high-profile resistance efforts. Mining Country presents fascinating snapshots of Canadian mining past and present, from pre-contact Indigenous copper mining and trading networks to the famous Cariboo and Klondike Gold Rushes. Generously illustrated with more than 150 visuals drawn from every period of mining history, this book offers a thorough account of the story behind the industry.
Download or read book Proceedings of 10th International Kimberlite Conference written by D Graham Pearson and published by Springer Science & Business Media. This book was released on 2013-08-24 with total page 355 pages. Available in PDF, EPUB and Kindle. Book excerpt: International Kimberlite Conferences (IKCs) are special events that are held across the world once in four to five years. IKC is the confluence platform for academicians, scientists and industrial personnel concerned with diamond exploration and exploitation, petrology, geochemistry, geochronology, geophysics and origin of the primary diamond host rocks and their entrained xenoliths and xenocrysts (including diamond) to get together and deliberate on new advances in research made in the intervening years. Ever since the organization of first IKC in 1973 and its tremendous success, the entire geological world eagerly look forward to subsequent such conferences with great enthusiasm and excitement. The scientific emanations from IKCs continue to make significant impact on our understanding of the composition, nature and evolution of the planet we live on. The previous conferences were held at Cape Town (1973), Santa Fe, New Mexico (1977), Clermont-Ferrand, France, (1982), Perth, Western Australia (1987), Araxa, Brazil (1991), Novosibirsk, Russia (1995), Cape Town (1998), Victoria, Canada (2003) and Frankfurt, Germany (2008). The 10th IKC was held at Bangalore, India between 5th and 11th February 2012. The conference was organized by the Geological Society of India in association with the government organizations, academic institutions and Indian diamond mining companies. About 300 delegates from 36 countries attended the conference and 224 papers were presented. The papers include 78 oral presentations and 146 poster presentations on following topics: Kimberlite geology, origin, evolution and emplacement of kimberlites and related rocks, petrology and geochemistry of metasomatised lithospheric mantle magmas, diamond exploration, cratonic roots, diamonds, diamond mining and sustainable developments and policies and governance of diamond exploration. Pre- and post-conference field trips were organized to (i) the diamond bearing kimberlites of Dharwar Craton in South India, (ii) lamproites of Bundelkhand Craton in northern India and (iii) diamond cutting and polishing industry of Surat, Gujarat in western India. A series of social and cultural programmes depicting cultural diversity of India were organized during the conference. The Kimberlite fraternity enjoyed yet another socially and scientifically successful conference.

Available in PDF, EPUB and Kindle. Book excerpt: In this book, the first dedicated entirely to the petrology of lamproites and their relationships to other potassium-rich rocks, the objective of the authors is to provide a comprehensive critical review of the occurrence, mineralogy, geochemistry, and petrogenesis of the clan. Although lamproites represent one of the rarest of all rock types, they are both economically and scientifically important and we believe the time is ripe for a review of the advances made in their petrology over the past two decades. Many of these advances stem from the recognition of diamond-bearing lamproites in Western Australia and the reclassification of several anomalous diamond-bearing kim berlites as lamproites. Consequently lamproites, previously of interest only to a small number of mineralogists specializing in exotica outside the mainstream of igneous petrol ogy, have become prime targets for diamond exploration on a worldwide basis. Contemporaneously with these developments, petrologists realized that lamproites possess isotopic signatures complementary to those of midoceanic ridge basalts, alkali basalts, kimberlites, and other mantle-derived melts. These isotopic studies provided new insights into the long-term development of the mantle by suggesting that the source regions of lamproites were metasomatically enriched in light rare earth and other incompatible elements up to 1-2 Ga prior to the melting events leading to generation of the magma.

Download or read book Composition Deep Structure and Evolution of Continents written by R.D. van der Hilst and published by Elsevier. This book was released on 1999-10-22 with total page 355 pages. Available in PDF, EPUB and Kindle. Book excerpt: The ensemble of manuscripts presented in this special volume captures the stimulating cross-disciplinary dialogue from the International Symposium on Deep Structure, Composition, and Evolution of Continents, Harvard University, Cambridge, Massachusetts, 15-17 October 1997. It will provide an update on recent research developments and serve as a starting point for research of the many outstanding issues.After its formation at mid-oceanic spreading centers, oceanic lithosphere cools, thickens, and subsides, until it subducts into the deep mantle beneath convergent margins. As a result of this continuous recycling process oceanic lithosphere is typically less than 200 million years old (the global average is about 80 Myr). A comprehensive, multi-disciplinary study of continents involves a wide range of length scales: tiny rock samples and diamond inclusions may yield isotope and trace element signatures diagnostic for the formation age and evolution of (parts of) cratons, while geophysical techniques (e.g., seismic and electromagnetic imaging) constrain variations of elastic and conductive properties over length scales ranging from several to many thousand kilometers. Integrating and reconciling this information is far from trivial and, as several papers in this volume document, the relationships between, for instance, formation age and tectonic behavior on the one hand and the seismic signature, heat flow, and petrology on the other may not be uniform but may vary both within as well as between cratons. These observations complicate attempts to determine the variations of one particular observable (e.g., heat flow, lithosphere thickness) as a function of another (e.g., crustal age) on the basis of global data compilations and tectonic regionalizations.Important conclusions of the work presented here are that (1) continental deformation, for instance shortening, is not restricted to the crust but also involves the lithospheric mantle; (2) the high wavespeed part of continental lithospheric mantle is probably thinner than inferred previously from vertically travelling body waves or form global surface-wave models; and (3) the seismic signature of ancient continents is more complex than expected from a uniform relationship with crustal age.
Download or read book Under Pressure written by Lindsay A, Bell and published by University of Toronto Press. This book was released on 2023-04-27 with total page 139 pages. Available in PDF, EPUB and Kindle. Book excerpt: In 2007, Canada became the third largest producer of diamonds in the world. Primarily mined on the edge of the Arctic, these diamonds are said to bring economic development and opportunity to nearby Indigenous communities. In Under Pressure, anthropologist Lindsay A. Bell examines the effects of diamond mining on an increasingly diverse northern population. Through an ethnographic focus on everyday life in Hay River, a multi-ethnic town in the Northwest Territories, this book illustrates the different ways Indigenous, settler, and immigrant northerners navigate the opportunities and obstacles created by large-scale resource development. By situating contemporary diamond mines within the long history of extraction in the region, Bell describes the social, cultural, and economic pressures that shape the people in this Northern community. In contrast to many polarizing accounts that deem mining as either good or bad, Under Pressure uses diamonds as an anthropological prism to consider larger issues related to Arctic extraction, globalization, Indigenous rights, and ethical consumption.
