Добрый день, Коллеги. Важное сообщение, просьба принять участие. Музей Ферсмана ищет помощь для реставрационных работ в помещении. Подробности по ссылке
Although it is generally understood that the Antarctic Ice Sheet plays a critical role in the changing global system, there is to date still a lack of generally available information on the subject. Climatic change and the role of the polar areas are often discussed in the media.
Craters on the Earth are traces on the path our planet has followed to come to existence from the early nebula which was filling this corner of the galaxy. Millions of cataclysmic events were necessary about five billions of years ago to form the Earth. We do not have evidences of this part of the Earth history on the surface. However, impacts continued through the Ages and traces of the most recent craters are present over the surface of the Earth. Documenting them through satellite observations provides important information on the genesis of our planet through a very valuable, systematic observational approach.
Geostatistical techniques are extensively used for mineral resources assessment, including grade estimation and uncertainty analysis. Support is the term used in Geostatistics to describe the size or volume of a sample. For example, suppose a grade sample obtained from diamond drill holes (DDH). In this case, the support is a function of the core’s radius and length.
The Second European Conference on Geostatistics for Environmental Applications took place in Valencia, November 18-20, 1998. Two years have past from the first meeting in Lisbon and the geostatistical community has kept active in the environmental field. In these days of congress inflation, we feel that continuity can only be achieved by ensuring quality in the papers. For this reason, all papers in the book have been reviewed by, at least, two referees, and care has been taken to ensure that the reviewer comments have been incorporated in the final version of the manuscript. We are thankful to the members of the scientific committee for their timely review of the scripts. All in all, there are three keynote papers from experts in soil science, climatology and ecology and 43 contributed papers providing a good indication of the status of geostatistics as applied in the environmental field all over the world. We feel now confident that the geoENV conference series, seeded around a coffee table almost six years ago, will march firmly into the next century. <...>
Landforms and landscapes vary enormously across the Earth, from high mountains to endless plains. At a smaller scale, Nature often surprises us by creating shapes which look improbable. Many physical landscapes are so immensely beautiful that they have received the highest possible recognition—they hold the status of World Heritage properties. Apart from often being immensely scenic, landscapes tell stories which not uncommonly can be traced back in time for tens of million years and include unique events.
Investment decisions are critical part of a company’s success, and capital budgeting is a central topic of financial management. However, in contrast to other strategic decisions in business, decisions on capital projects are decentralized, from corporate to divisions, divisions to operations, from operations to departments. Engineers at various levels within the organization who make a capital proposal are contributing to the strategic success of the organization. This book will assist engineers to contribute strategically to the organization, so that they can contribute to the success of their company and can make a success of their careers.<...>
This book contains chapters presented at the International workshop ‘Minerals as Advanced Materials I’ that was held in the hotel of the Russian Academy of Sciences on the Imandra lake, Kola peninsula, one of the most beautiful places of the Russian North, during 8–12 July, 2007. The idea of the workshop originated from the necessity of interactions between mineralogy and material science, including all aspects of both these disciplines. Many important materials that dominate modern technological development were known to mineralogists for hundreds years, though their properties were not fully recognized. Mineralogy, on the other hand, needs new impacts for the further development in the line of modern scientific achievements, including novel insights provided by development of bio- and nanotechnologies as well as by the understanding of a deep role that information plays in the formation of natural structures and definition of natural processes. <...>
Basin analysis is a comprehensive approach to decipher the geological evolution of a basin by constructing the stratigraphic framework and facies relationships, by mapping and understanding the geological structures in light of their historical development, and by examining the physical and chemical properties of rocks and their sedimentological and petroleum attributes. The purpose of the analysis is to identify potential source rocks and reservoir rocks, and to evaluate the maturation, generation, migration, and entrapment of hydrocarbons in a sedimentary basin. <...>
Vesuvianite-group minerals (VGM) are widespread and occur in different geological formations including regional metamorphic rocks, skarns, rodingites, etc. Specific crystal-chemical features of these minerals reflect conditions of their crystallization. As a rule, high-temperature VGM have high-symmetry structures (space group P4/ nnc), whereas low-temperature samples are characterized by the symmetry P4/n or P4nc (Allen and Burnham 1992).
While ancient man must have had some intuitive knowledge of geology, as evidenced by the feats of mining and civil engineering performed in the distant past, the present science of geology owes much of its origin to the civil engineers working in the eighteenth century. These engineers, while constructing the major engineering works associated with the industrial revolution, had the opportunity to view and explore excavations in rocks and soils. Some, intrigued by what they saw, began to speculate on the origin and nature of rocks, and the relationships between similar rocks found in different places. Their ideas and theories, based on the practical application of their subject, formed the groundwork for the development of geology as a science. Engineers such as Lewis Evans (1700–1756) in America, William Smith (1769–1839) in England, Pierre Cordier (1777–1862) in France and many others were the ‘fathers’ of Geology. <...>
