This book was released on 1991 with total page 478 pages. Available in PDF, EPUB and Kindle. Book excerpt: "K-feldspars from two single type source areas were analyzed by X-ray powder diffraction methods to evaluate the effectiveness of structural state for provenance interpretation. For this purpose 21 rock and stream sediment samples were collected from Golden Horn batholith area, Washington (alkali feldspar granite source) and 17 rock and stream sediment samples were collected from Topaz Mountain area, Utah (rhyolite source). Sediment samples were sieved into thirteen fractions to determine if the size affects the structural state of detrital alkali feldspars. The structural state of alkali feldspars from rock and sediment samples was determined by plotting the refined b and c cell parameters on the b-c quadrilateral of Wright and Stewart(1968). The results show a strong correlation between the structural state of alkali feldspars from rocks and that of the sediments in both the study areas. Grain size and transport distance of the sediments had no observable effects on the structural state of the detrital feldspars. Further studies are suggested in areas of multiple source rocks and on ancient sediments that have undergone various degrees of diagenetic changes. This method can be used with plagioclase feldspars for provenance interpretation when used in conjunction with microprobe analytical data"--Document.

This book was released on 2012-12-06 with total page 391 pages. Available in PDF, EPUB and Kindle. Book excerpt: Masters Theses in the Pure and Applied Sciences was first conceived, published, and disseminated by the Center for Information and Numerical Data Analysis and Synthesis (CINDAS)* at Purdue University in 1957, starting its coverage of theses with the academic year 1955. Beginning with Volume 13, the printing and dis semination phases of the activity were transferred to University Microfilms/Xerox of Ann Arbor, Michigan, with the though that such an arrangement would be more beneficial to the academic and general scientific and technical community. After five years of this joint undertaking we had concluded that it was in the interest of all concerned if the printing and distribution of the volumes were handled by an international publishing house to assure improved service and broader dissemi nation. Hence, starting with Volume 18, Masters Theses in the Pure and Applied Sciences has been disseminated on a worldwide basis by Plenum Publishing Corporation of New York, and in the same year the coverage was broadened to include Canadian universities. All back issues can also be ordered from Plenum. We have reported in Volume 37 (thesis year 1992) a total of 12,549 thesis titles from 25 Canadian and 153 United States universities. We are sure that this broader base for these titles reported will greatly enhance the value of this impor tant annual reference work. While Volume 37 reports theses submitted in 1992, on occasion, certain uni versities do report theses submitted in previous years but not reported at the time.

Available in PDF, EPUB and Kindle. Book excerpt: During the past two centuries, crystallography, mineralogy and petrology have evolved from simple compilations of data to powerful disciplines based on interlocking networks of laws, hypotheses and rules-of-thumb. While many data still consist of isolated facts which defy synthesis, a gratifying portion can be organized according to physical and chemical principles. Unfortunately the separation of physical sciences into sub-divisions, especially at the teaching level, makes it difficult to integrate the different approaches to minerals. This separation is worsened by the increasing technical demands of chemical and physical theories, by the number and complexity of experimental methods, by the sheer mass of facts in an observational discipline such as mineralogy or petrology, and by the explosion of papers. This book concentrates on those aspects of the genesis and properties of feldspar minerals which can be related to physical and chemical principles. My main aim is frankly pedagogic: I wish to show how chemical and physical principles can be combined with geologic observation to produce an enhanced level of understanding of the genesis of minerals. The feldspars which demonstrate almost all of the general principles provide the most suitable example.

Available in PDF, EPUB and Kindle. Book excerpt: Remarks by JVS. Volumes 1 and 2 of Feldspar Minerals were published in 1974, but Volume 3 was not completed because I was forced to devote 3 years to the resolution of unforeseen problems in the construction of an ion probe. By 1977, the incomplete draft for Volume 3 had become obsolete because of the enormous advances in knowledge of feldspars, particularly those in lunar rocks and meteorites, and in both deep-seated and ancient terrestrial rocks. Furthermore, it soon became obvious that a completely new version of Feldspar Minerals was needed because of the important new results on the physical and chemical properties. I had kept up with the interesting but tedious chore of weekly reading of the incoming literature and maintenance of the files. By 1980, the intense day-to day pressure had gone from my research programs on lunar rocks and on the development of the ion microprobe as a quantitative geochemical instrument, and I began preparation of a second edition of Feldspar Minerals.
Download or read book Feldspars and Feldspathoids written by W.L. Brown and published by Springer Science & Business Media. This book was released on 2013-04-17 with total page 551 pages. Available in PDF, EPUB and Kindle. Book excerpt: The feldspars form the most abundant group of minerals in the crust of the Earth and Moon and also occur in many meteo rites. They playa fundamental role in all rock-forming processes at shallow depths, but are rare or absent from the upper mantle. Their detailed study is thus essential for the understan ding of such varied processes as magma genesis and differentia tion, metamorphism, al teration, erosion and sedimentation. This interest is show by the fact that two previous NATO Advanced Study Institutes on feldspars were held in Oslo in 1962 and in Manchester in 1972. The feldspars are particularly sui table for detailed studies, as they have very simple chemistry and develop some of the most complex microstructures known. The microstructures are often slow to form but are easily preserved, so that they are potentially extremely informative about the geological history of the rocks in which they occur. Furthermore, their study involves physical and chemical methods of increasing sophistication so that the results obtained are not always immediately understandable to research workers outside the field of modern mineralogy. Progress in knowledge about feldspars is probably slower in penetrating the fields of petrology and geochemistry than that on other mineral groups. For these reasons among others, i~ was particularly appropriate to hold a third NATO ASI on feldspars approximately ten years after the last one.

Download or read book Feldspars and their Reactions written by Ian Parsons and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 672 pages. Available in PDF, EPUB and Kindle. Book excerpt: Feldspar minerals make up 60% of the crust of the Earth. They are stable in the upper mantle, and are so abundant in the crust that they form the basis of the classification of igneous rocks. At the surface, feldspars weather to form clay minerals which are the most important mineral constituent of soils. The articles in this book review the chemical reactions of feldspars over the whole sweep of pressure and temperature regimes in the outer Earth, and describe the fundamental aspects of crystal structure which underlie their properties. The book covers intracrystalline reactions, such as order-disorder transformations and exsolution, and transfer of stable and radiogenic isotopes, which can be interpreted to provide insights into the thermal history of rocks. It is suitable for final year undergraduates or research workers.
Download or read book Electron Diffraction Analysis of Clay Mineral Structures written by B. B. Zvyagin and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 381 pages. Available in PDF, EPUB and Kindle. Book excerpt: As a method of structure analysis, electron diffraction has its own spe cial possibilities and advantages in comparison to the X -ray method for the study of finely dispersed minerals with layer or pseudolayer structures. How ever, possibly because of the prior existence of the X-ray method, which found universal application in different fields and attracted the main efforts of spe cialists, electron diffraction has been unevenly disseminated and developed in different countries. In particular, the oblique texture method, which gives very complete and detailed structural information, has been mainly used in the Soviet Union, where electron-diffraction cameras specially suited to the method have been constructed. In other countries, studies have been made of micro-single crystals, because these studies could be carried out with existing electron microscopes. It should be recognized that the scale of distribution and use attained by electron-diffraction methods, at present limited by exist ing experimental conditions. is more than justified by the value of the results which may be obtained by their aid. The author hopes that the present book will give the reader a fuller idea of the valuable advantages of the method, and of the structural crystallography picture which has been built up for clay minerals, and layer silicates in general, from electron-diffraction data. The time between the appearance of this book and that of the Russian edition has been comparatively short.

Download or read book Petrology of Sedimentary Rocks written by Sam Boggs and published by . This book was released on 2003 with total page 728 pages. Available in PDF, EPUB and Kindle. Book excerpt: Originally published in 1992, Petrology of Sedimentary Rocks is now back in print and available. In Petrology of Sedimentary Rocks, Dr. Sam Boggs wrote what has come to be considered the definitive text on the subject of sedimentary petrology. The book is intended for students at the senior and graduate level. The text provides a comprehensive description, classification and interpretation of all major sedimentary rock groups. The essential aspects of diagenesis, particle and chemical composition, and provenance receive unparalleled coverage. Photographs, line drawings and tables are utilized to enhance understanding and illustrate sedimentary structures, textures and compositions. A clear, fluid writing style distills the vast amount of information contained in the text, and presentation of controversial topics provides students with insight into divergent views and opinions. Prior to receiving his Ph.D. in geology from the University of Colorado in 1964, Sam Boggs worked as a petroleum exploration geologist for the Phillips Petroleum Company. On completion of his doctorate, Dr. Boggs conducted research for Esso Production Research, applying geological and geophysical techniques to interpret the stratigraphic characteristics of sedimentary sequences and stratigraphic controls on oil accumulation in major U.S. basins. During his career, Dr. Boggs, has authored many papers in sedimentary petrology, geological oceanography, stratigraphy and organic geochemistry.
Download or read book Feldspar Mineralogy written by Paul H. Ribbe and published by Walter de Gruyter GmbH & Co KG. This book was released on 2018-12-17 with total page 376 pages. Available in PDF, EPUB and Kindle. Book excerpt: Volume 2 of Reviews in Mineralogy displays the Short Course on Feldspar Mineralogy in Salt Lake City in October 1975. The workshops on x-ray single-crystal, powder diffraction methods and electron optical techniques as applied to the study of feldspars are the substance of which became the nine chapters of the first edition of Feldspar Mineralogy. It will be noted by readers experienced with feldspars that there are many new ideas appearing in Chapters 3, 4 and 5 that have neither received scrutiny by review (other than ourselves) nor survived practical tests of time in the research community. There is some danger in this, but the editor decided the greater risk was to produce a review volume soon to be outdated. Inevitably, given the different goals of individual authors in their assigned topics, some repetition of material has occurred, although usually with quite different emphases. Chapters 1, 2, 9 and 10, in which plagioclase structures and diffraction patterns and their Al,Si distributions, phase equilibria and exsolution textures are featured, are notable in this regard.
