Mineral resource estimation has changed considerably in the past 25 years: geostatistical techniques have become commonplace and continue to evolve; computational horsepower has revolutionized all facets of numerical modeling; mining and processing operations are often larger; and uncertainty quantification is becoming standard practice. Recent books focus on historical methods or details of geostatistical theory. So there is a growing need to collect and synthesize the practice of modern mineral resource estimation into a book for undergraduate students, beginning graduate students, and young geologists and engineers. It is especially fruitful that this book is written by authors with years of relevant experience performing mineral resource estimation and with years of relevant teaching experience. This comprehensive textbook and reference fills this need.

This book is intended to provide the reader with information regarding diamond prospecting. It also points out areas to prospect. I have prospected in this area of Virginia and West Virginia in the past, but my ill health prevents me doing it anymore. It's all yours now. Finding diamonds will not be that difficult, but remember, they should be two carats or larger and free of flaws to be worth much. You may want to save everything smaller, too. Some third world company may purchase them from you.

Minerals and Human Health is written in response to the demand for additional knowledge about global climate change, the industrial contamination of water reservoirs, and epidemiological intoxication from industrial hazards related to the use of mineral resources. The book addresses issues associated with the physical and geological processes of the Earth, the sustainability and fragility of the Earth's resources, and the interplay between health, industrial activities, and environments. It combines mineralogy, medicine, and the environmental, life, and political sciences to develop solutions to ease human suffering from geological toxicity. Minerals and Human Health helps students to understand the Earth's activities and the unique resources that sustain life and facilitate industrial progress. The text teaches readers how the dispersal of geological materials effects the human population. In-book quizzes allow students to assess their own progress. Questions for discussion and review encourage critical thinking and debate and support retention. Minerals and Human Health can be used in courses on earth and environmental sciences, geopollution, and geochemistry.

Here is a state-of-the-art survey of artificial intelligence in modern exploration programs. Focussing on standard exploration procedures, the contributions examine the advantages and pitfalls of using these new techniques, and, in the process, provide new, more accurate and consistent methods for solving old problems. They show how expert systems can provide the integration of information that is essential in the petroleum industry when solving the complicated questions facing the modern petroleum geoscientist.

By definition, biosphere is the Earth's geological shell populated by living organisms. Therefore, the biosphere's origin and evolution are primarily a geological problem. At present geological problems are solved using methods of physics, chemistry, biology, and mathematics. The multidisciplinary approach is a basis of this book. Life origin problems occupy the main part of this book. What is life, and can we understand its origin and evolution on the basis of laws of physics and chemistry? A number of works are dedicated to experimental study of the synthesis of organic compounds of the prebiotic significance, including ATP and photoactive systems. The characteristic feature of our scientific approach is to consider the problem of life origin in the context of the origin and evolution of the solar system, beginning with the protoplanetary stage and including the events of the Earth's early history. The last chapter comprises papers that concern modern problems and approaches to the study of various aspects of biological evolution. The present edition is a collection of articles by scientists representing more than 20 institutes of the Russian Academy of Sciences and other organisations, joined by the science program "Problems of Biosphere Origin and Evolution". This book will be interesting for a wide range of researchers: physicists, chemists, biologists, mathematicians. The book represents the stance of the Russian scientific school on the problem of life origin, which does not always coincide with opinions of other scientific schools.

This work presents mathematical models for pressure and saturation distributions of oil and water flow through semi-infinite porous media. The mathematical models were developed from the popular Darcy's equation and the continuity equation. The mathematical model, which contains simultaneously saturation and pressure gradients, was decoupled to have a pure pressure and saturation differential equations. The Crank-Nicolson Finite Difference Method was used to provide solution to the partial differential equations. System of linear equations resulted from the discretized partial differential equations were solved for saturation and pressure distributions using the Modified Gaussian Elimination Method algorithm, which was implemented in Microsoft Excel Visual Basic for Application. The solution was tested using hypothetical oil/water well production data. The solution scheme and computer language adopted in this work are easy to apply and use as opposed to the sophisticated and expensive computer software used by most researchers in the area.

Elliot L. Richardson The United States is finally awakening to the fact that it has a major stake in the future of the Arctic. Recognition of the national importance of the Arctic has been slow in coming despite the resource wealth that Arctic Alaska has thus far yielded. Although the United States has had strategic interests in the Arctic since World War II and active oil and gas interests there since the discovery of oil at Prudhoe Bay in 1968, its interest in the Arctic has been low in comparison with that of its Arctic neighbors, Canada and the Soviet Union. What has been described by some as an attitude of neglect toward the Arctic is now changing. The notion of change has become central in most current discussions about the future of the Arctic. It is apparent that the Arctic region is entering a period of greatly accelerated economic, social, strategic, and is political change. The driving force behind the changes taking place resource development activity, and although the present scale of this activity is not inconsequential, it is small in comparison to its projected growth in the next two decades. In short, the Arctic is about to come alive. However, knowledge of the Arctic and experience in the Arctic is comparatively limited. Moreover, competing interests and differing val ues exist among national groups and between countries in the Arctic, just as they do in the lower latitudes."
