Beschreibung / Inhaltsverzeichnis: Digital signal processing has become more and more an integral part of observational seismology. While it offers unprecedented power in extracting information from seismic signals, it comes at the price of having to learn a variety of new skills. Dealing with digital seismic data requires at least a basic understanding of digital signal processing. Taking the calculation of true ground motion as the guiding problem, this course covers the basic theory of linear systems, the design and analysis of simple digital filters, the effect of sampling and A/D conversion and an introduction to spectral analysis of digital signals. It contains a number of examples and exercises that can be reproduced using the PITSA software package (Scherbaum and Johnson 1993) or similar programs.

Beschreibung / Inhaltsverzeichnis: Knowledge of the relation between sonic velocity in sediments and rock lithology is one of the keys to interpreting data from seismic sections or from acoustic logs of sedimentary sequences. Reliable correlations of rock velocity with other petrophysical parameters, such as porosity or density, are essential for calculating impedance models for synthetic seismic sections (BIDDLE et al. , 1992; CAMPBELL and STAFLEU, 1992) or identifying the origin of reflectivity on seismic lines (SELLAMI et al. , 1990; CHRISTENSEN and SZYMANSKI, 1991). Velocity is thus an important parameter for correlating lithological with geophysical data. Recent studies have increased our understanding of elastic rock properties in siliciclastic or shaly sediments. The causes for variations in velocity have been investigated for siliciclastic rocks (VERNIK and NUR, 1992), mixed carbonate siliciclastic sediments (CHRISTENSEN and SZYMANSKI, 1991), synthetic sand-clay mixtures (MARION et aI. , 1992) or claystones (JAPSEN, 1993). The concepts derived from these studies are however only partly applicable in pure carbonates. Carbon­ ates do not have large compositional variations that are, as is the case in the other sedimentary rocks, responsible for velocity contrasts. Pure carbonates are character­ ized by the lack of any clay or siliciclastic content, but are mostly produced and deposited on the top or on the slope of isolated or detached carbonate platforms, that have no hinterland as a source of terrigeneous material (WILSON, 1975; EBERLI, 1991).

Beschreibung / Inhaltsverzeichnis: The study of opaque minerals or synthetic solids in polished section using the polarizing reflected-light microscope is the most important technique for the identification and characterization of the opaque phases in a sample and the textural relationships between them. Since most metalliferous ores are comprised of opaque minerals, this study has been traditionally known as ore microscopy and has found its greatest applications in the study of mineral deposits. It may be applied, however, as a general technique in the study of igneous, sedimentary, or metamorphic rocks containing opaque minerals and even in the study of metallurgical products or other synthetic materials. The objective of this text is to present an up-to-date introduction to ore microscopy for the student or professional scientist who is unfamiliar with the technique-an introduction that would accompany a course at the senior undergraduate or graduate level or that would provide the professional with a first step in familiarization. No attempt has been made at a comprehensive treatment of the subject; for this the reader is referred to the excellent works of such authors as Rarndohr, Uytenbogaart and Burke, Galopin and Henry cited in relevant sections ofthis text. Emphasis is placed on the basic skills required for the study of opaque minerals in polished section, and information in the text and appendices on the more common ore minerals and assemblages provides examples. The first two chapters cover the design and operation of the ore microscope and the preparation of polished (and polished thin) sections. A chapter dealing with qualitative mineral properties used in identification is followed by a discussion of reflected-light optics. The quantitative measurement of reflectance, color, and microhardness are treated in Chapters 5 and 6 along with overall schemes for employing these measurements in identification. Chapters 7 and 8 deal with ore mineral textures and paragenesis, and include a brief discussion of the study of fluid inclusions. Chapters 9 and 10 are concise discussions of many of the major ore mineral associations observed under the microscope. These discussions are not intended to be exhaustive, especially with regard to comments made on the genesis of the ores, but are designed to aid understanding by placing the ore mineral textures and associations in a broader geological context. Chapter 11 deals with the applications of ore microscopy in mineral technology. The appendices contain the data necessary to identify approximately 100 of the more common ore minerals-those likely to be encountered by the student in an introductory course andthose frequently encountered by the professional scientist. Key references to more detailed accounts are provided throughout the text. The dependence ofthe properties, textures, and associations of the minerals on their crystal chemistry, thermochemistry, and phase relations is an aspect of modern studies of ore minerals that is particularly emphasized. This second edition retains the overall structure of the first edition. Chapters 1and 2, dealing with the ore microscope and with the preparation of samples for ore microscopy, have been updated and revised to take account of technical developments. Chapters 3 and 4 deal with qualitative methods of mineral identification and with reflected light optics, and remain largely unchanged. Chapters 5 and 6 deal with quantitative methods in reflected-light microscopy and have been revised to include new technical developments and advances in theory. Chapters 7 and 8, dealing with ore mineral textures, paragenesis, formation conditions, and fluid inclusions, incorporate new data and examples. Chapters 9 and 10, which cover the most important examples of ore mineral assemblages, have been rewritten so as to incorporate many new references to original studies that have been performed in the years since the publication of the first edition. Developments have also taken place in the applications of ore microscopy in mineral technology and in the study of both the products of milling and concentration of ores,and the synthetic analogs of minerals that occur in metallurgical, corrosion, and waste products. As in the first edition, an important feature of this text is the incorporation of appendices detailing and tabulating the diagnostic properties of about 100 ofthe most common ore minerals. These data tabulations have been updated using the most recently available quantitative data. Another appendix, which briefly describes ancillary techniques for the study of ore minerals, has been extended to include the most recent innovations.

Beschreibung / Inhaltsverzeichnis: Volatile components, by which we mean those magma constituents which typically prefer to occur in the gaseous or super-critical fluid state, may influence virtually every aspect of igneous petrology. The study of volatile-bearing systems, both in nature and in the laboratory, has far exceeded the relative abundances of these components in igneous rocks, yet in many ways the words of Bowen (1928) are still broadly applicable: " ... to many petrologists a volatile component is exactly like a Maxwell demon; it does just what one may wish it to do." (Bowen, 1928, p. 282) What we hope to show in this volume are some areas of progress in understanding the behavior of magmatic volatiles and their influence on a wide variety of geological phenomena; in doing this it also becomes apparent that there remain many questions outstanding. The range of topics we have tried to cover is broad, going from atomisticscale aspects of volatile solubility mechanisms and attendant effects on melt physical properties, to the chemistry of volcanic gases and the concentrations of volatiles in magmas, to the global geochemical cycles of volatiles. The reader should quickly see that much progress has been made since Bowen voiced his concerns about Maxwell demons, but like much scientific progress, answers to old questions have prompted even greater numbers of new questions. The Voltiles in Magmas course was organized and transpired at the Napa Valley Sheraton Hotel in California, December 2-4, 1994, just prior to the Fall Meetings of the American Geophysical Union in San Francisco.
