Every little wiggle has a meaning all its own. This is our underlying faith, that details of seismic waveshapes can tell us the details of the nature of the earth. But their voices are obscured by many irrelevancies. They speak in a high-noise environment, and we have been able to decipher only a small portion. However, things are looking up: better tech niques are lessening the irrelevancies, and we are learning to read. In exploration of unknown areas, determining the nature of the rocks...

Why do volcanoes go "ka-boom!"? This unique approach to vulcanology is highly inspiring to young children. The use of carefully selected images only help in driving home certain points of discussion. This is a picture book that your child will definitely love and learn the most from. Don't forget to grab a copy today!

Biomass burning profoundly affects atmospheric chemistry, the carbon cycle, and climate and may have done so for millions of years.Bringing together renowned experts from paleoecology, fire ecology, atmospheric chemistry, and organic chemistry, the volume elucidates the role of fire during global changes of the past and future. Topics covered include: the characterization of combustion products that occur in sediments, including char, soot/fly ash, and polycyclic aromatic hydrocarbo...

Carbonate sediments are of increasing relevance for archives of past environmental conditions and for economical reasons in areas of geothermal energy and hydrocarbon reservoirs. Complex interaction of physical and chemical parameters with biological parameters determines the architecture and composition of carbonate sedimentary bodies. This book closes some of the still existing gaps in our understanding of the influence and interplay of physical, chemical, and biological parameters with ...

In modern sediment research on contaminants five aspects are discussed which, in an overlapping succession, also reflect develop ment of knowledge on particle-associated pollutants during the past twenty-five years: (1) identification of sources and their distribution; (2) evaluation of solid/solution relations; (3) study of transfer mecha nisms to biological systems; (4) assessment of environment impact; and (5) selection and further development of remedial measures, in par ticular, of dr...

We live in an early stage of an interglacial period, which began some fifteen thousand years ago - a warming trend which, with the extreme ups and downs, is . still gaining momentum. There is little doubt that, sometime in the foreseeable future, the global climate will inexorably become much warmer l and many regions, such as the Near East, will become much drier. We even accelerate this process by recklessly pumping carbon dioxide from fossil fuels into the atmosphere. And if that is not...

Periplatform slope sediments from the Bahamas serve as an example for a small-scale sedimentologic record of environmental changes. Carbonate platforms react sensitively to sea-level fluctuations. Therefore, sediments deposited on the slope during lowstands differ in composition from highstand deposits. A second focus is the early diagenetic alteration and cementation of these sediments with their high diagenetic potential. This book contributes to and discusses new developments in carbona...

Magic of Minerals and Rocks, featuring 135 splendid color photographs, ranges from vast rock-landscapes recorded in Europe, America, Australia, and Iceland right down to finely detailed images of a few square millimeters. Close-ups of crystals, gems, and fossils are alternated with micro-images of the minute textures and patterns that emerge from thin, translucent sections of rocks and minerals. Literally, as well as figuratively Dirk Wiersma, the photographer, 'zooms in' ...

Dykes occur in a wide variety of geological and tectonic settings and their detailed study through space and time is imperative for understanding several geological events. Dykes are believed to be an integral part of continental rifting and when they occur as spatially extensive swarms of adequate size, they can be of immense utility in continental reconstructions and also help to identify Large Igneous Provinces (LIPs). It is known that continental flood basalts and major dyke swarms hav...

1 2 J. H. SCHROEDER and B. H. PURSER 1 Introduction A symposium convened during the Vth International Coral Reef Congress in Papeete, Tahiti, 1985, encouraged the editors to assemble this volume of case studies by participating and, especially, by nonparticipating scientists. An attempt was made to include case studies from various regions and geological periods, carried out on various scales from regional to ultrastructural. We hope to present an overall view of reef diagenesis. Although ...

Nonrenewable energy resources, comprising fossil fuels and uranium, are not ran domly distributed within the Earth's crust. They formed in response to a complex array of geologic controls, notably the genesis of the sedimentary rocks that host most commercial energy resources. It is this genetic relationship between economic re sources and environment that forms the basis for this book. Our grouping of petro leum, coal, uranium, and ground water may appear to be incongruous or artificial. ...
