Volume 2, dedicated to Barry Hawthorne, presents papers concerned with the genesis of eclogites, the mineralogy of diamond and its inclusions, exploration methods for kimberlite, the geochemistry of the upper mantle and the character of cratons.
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.
This extensively updated new edition of the widely acclaimed Treatise on Geochemistry has increased its coverage beyond the wide range of geochemical subject areas in the first edition, with five new volumes which include: the history of the atmosphere, geochemistry of mineral deposits, archaeology and anthropology, organic geochemistry and analytical geochemistry. In addition, the original Volume 1 on "Meteorites, Comets, and Planets" was expanded into two separate volumes dealing with meteorites and planets, respectively. These additions increased the number of volumes in the Treatise from 9 to 15 with the index/appendices volume remaining as the last volume (Volume 16). Each of the origin...
Electron paramagnetic resonance (EPR) applications remain highly significant in modern analytical science and this volume compiles critical coverage of developments in the recent literature by a handpicked group of researchers at the cutting-edge of the field.
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 excite...
The Crisis, founded by W.E.B. Du Bois as the official publication of the NAACP, is a journal of civil rights, history, politics, and culture and seeks to educate and challenge its readers about issues that continue to plague African Americans and other communities of color. For nearly 100 years, The Crisis has been the magazine of opinion and thought leaders, decision makers, peacemakers and justice seekers. It has chronicled, informed, educated, entertained and, in many instances, set the economic, political and social agenda for our nation and its multi-ethnic citizens.
Confronting a reality that many policy makers would prefer to ignore, contributors to this volume offer the latest information on the trend toward the racial and socioeconomic resegregation of southern schools. In the region that has achieved more widespread public school integration than any other since 1970, resegregation, combined with resource inequities and the current "accountability movement," is now bringing public education in the South to a critical crossroads. In thirteen essays, leading thinkers in the field of race and public education present not only the latest data and statistics on the trend toward resegregation but also legal and policy analysis of why these trends are acce...
Taking into account the political and intellectual forces that shape Supreme Court decisions, Constitutional Debate in Action examines how and why the U.S. Constitution continues to grow and adapt to human wants, passions, and values. Not your traditional constitutional-law textbook, this three-volume set views the Constitution as an institutionalized form of debate by which people press their political demands and arguments upon the Supreme Court. This process-oriented approach goes beyond a straightforward examination of how the decisions of Supreme Court justices have transformed constitutional doctrine through the ages; it explores the actual process of adjudication itself. Each case stu...
This update to SAT Wars provides new evidence in the case against standardized college entry tests, including the experiences of test-optional colleges. The Scandal of Standardized Tests sheds significant light on key problems such as: Are the tests stronger proxies for race and family income today than they were 20 years ago? Does going test-optional promote racial and economic diversity? Are there any differences in academic records between students admitted without test scores and those with them? How does testing figure into race-sensitive admissions legal controversies? Why is the College Board’s “environmental dashboard” inadequate as a way to create a fair playing field? How are...
Multidisciplinary overview of lithospheric structure and evolution, based on a full set of geophysical methods, for researchers and advanced students.
