Добрый день, Коллеги. Важное сообщение, просьба принять участие. Музей Ферсмана ищет помощь для реставрационных работ в помещении. Подробности по ссылке
This volume is devoted to the memory of the Russian petrologist D.S. Korzhinskiy. The world community of geoscientists has highly valued his contributions to petrology, particularly the discovery and thermodynamic description of open systems with perfectly mobile components. Korzhinskiy's work reached this community's attention because his book Physicochemical Basis of the Analysis of the Paragenesis of Minerals (1959, Consultants Bureau, New York) was translated into English. However, in the Soviet Union D.S. Korzhinskiy is also highly regarded for his contributions to geology and study of ore deposits as well as to theoretical petrology. Stratigraphy and geology of the Precambrian Aldan shield in Eastern Siberia; origin of lapis lazuli and phlogopite deposits and iron formations; boron mineralization; genesis of skarns and general theory of metasomatic zoning; origin of granites, charnockites and anorthosites; theory of the acid-basic interaction of components in the dry silicate melts: all of these were subjects of his more than 200 papers and books. The papers in the present volume span Korzhinskiy's broad interests. These papers were selected with the aim of illustrating the progress made in physicochemical petrology since Korzhinskiy.
Earthquakes pose a significant threat to countries around the world. But, equipped with the right knowledge and tools, engineers and seismologists can support policy and decision-makers in creating a safer future for all of us. The Third European Conference on Earthquake Engineering and Seismology (3ECEES), jointly organized by Technical University of Civil Engineering of Bucharest (UTCB) and National Institute for Earth Physics (INFP) in Bucharest, Romania,
This book is about raising finance for the international petroleum industry, an industry that represents one of the most important sectors in the modern world’s economy. The activities of the petroleum industry span the globe and many of its products have become essential for modern society. At its core, the industry is about providing energy in the form of fuels, especially for transportation and electrical power generation. This is achieved by extracting and transporting raw materials from underground reservoirs, processing these materials into fuels and then delivering the final products to end-consumers in all parts of the world. This industry is, however, about more than just fuels. The hydrocarbon molecules that the industry extracts from the earth are also used to produce a wide range of other important materials. The petrochemicals industry produces the vast majority of synthetic materials including: plastics, polymers, synthetic rubbers, detergents, solvents and so on. The refining industry produces waxes, lubricants and bitumens. More specialist petroleum processes produce fertilisers, pharmaceuticals and other essential chemicals <...>
Our combined experiences in the global minerals industry are the central source for the effective project management tactics and methods that we seek to convey within this book. We are forever indebted to the corporations who so generously employed us and to our colleagues who so patiently educated us over these past 50 years. This publication is a culmination of the wisdom we gleaned and gathered from so many others as we worked our way through almost 500 projects following our entry into the mining profession.
The subject of project management has become one of the most common themes in the recent past, and that is due to the increase in the number of mega projects worldwide and the development of modern technology in all areas of knowledge, which requires new methods of project management to cope with fast-pace developing.
On the occasion of the 65th birthday of K Alex Muller (KAM), the IBM Zurich Research Laboratory in Ruschlikon, with the help of J. Georg Bednorz, offered a compilation of almost all the publications he had authored or co-authored. Those two volumes encompass thewritings until 1992. They are very useful to access KAM's earlier work, with the more than 300 papers arranged in chronological order. When KAM turned seventy, Prof. KK Phua, chairman of World Scientific, suggested to collect relevant original work in a volume to be published by this well-established house. After some reflection, Muller thought this might be a reasonable undertaking, and selected, from the then more than 400 original publications, those he considered the relevant ones. The result is this book with its eleven chapters, arranged in topological rather than chronological order. In each chapter the pertinent publications in one specific area of investigations are grouped together. Therefore it should be easy for the reader to find a paper of interest to him or her. To bring this work up to date, it also includes KAM's articles on the topics in this book published after 1992 and publications by Tom Kool, the second author, who worked in the field of oxide perovskites as well and kept helping to realize and edit the present volume <...>
Исследования Геологического Комитета в Крымском горном кряже доставили немало новых материалов, как для понимания морфологии, так и для тектоники и стратиграфии этих гор. В частности это касается и той песчаноглинистой толщи, которая слагает нижнюю часть склона Южного берега, а также значительныя площади на северном склоне кряжа. Эта толща является то более глинистой, и тогда почти черного цвета, с отдельными известковыми и сферосидеритовыми стяжениями и с пропластами плотных, более или менее железистых песчаников и вулканических туфов, то более песчаной и тогда более светлых цветов, обычно сильно слюдистой и с массой плохо сохраненныхъ растительных остатков; <...>
Pterosaurs (meaning ‘winged lizard’) were the first vertebrates to fly (figure 1) and are therefore often referred to as ‘flying reptiles’. However, like the dinosaurs, they are only remotely related to modern reptiles. For the same reason, it is not correct to refer to pterosaurs as ‘flying dinosaurs’.
Vein arrays are often composed of pull-aparts which are linked by shear fractures, good examples of which occur in the Lower Jurassic limestones of Somerset, southwestern England. Such pull-apart arrays have displacement-distance characteristics which are similar to fault zones, with maximum displacement (indicated by the largest pull-apart widths) near the centre of the array, and with displacement decreasing towards the tips. Pull-apart arrays usually die out into en echelon or pinnate veins. Evidence for pressure solution along the shear fractures which connect pull-aparts include their dark and braided nature, their obliquity to the displacement direction, the high dihedral angles (often > 90°) between conjugate shear fractures, and the dissolution of earlier structures. A range of geometries occurs, with varying relative amounts of veins and pressure solution being related to varying amounts of transtension or transpression. There is a general trend for an increase in the angle between vein segments and the shear fractures as contraction increases. There is therefore a trend for increased pressure solution on the shear fractures in more contractional arrays. The concentration of insoluble material along shear fractures has important implications for the mechanics and sealing of faults.
