Available in PDF, EPUB and Kindle. Book excerpt: Magnetic susceptibility (MS) is a tool frequently used by geologists on sediments or rocks to perform correlations and sea-level or climatic reconstructions. Applied measurements are made on unoriented, bulk samples and bulk MS is mostly influenced by the magnetic mineral content of the rock and often interpreted as influenced by detrital inputs. Magnetic data acquisition is fast and straightforward and this allows the high-resolution sampling needed for palaeoclimatic research (e.g. spectral analysis). However, the link with detrital inputs is not always preserved and the impact of diagenesis on the final MS signal can blur primary information. This volume includes contributions dealing with the origin of the magnetic minerals, and the application of MS as a palaeoenvironmental or palaeoclimatic proxy and also as a tool to provide astronomical calibration in order to improve the chronology of selected time intervals.

This book was released on 2012 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The management of a petroleum reservoir requires good understanding of the geology and the properties of the reservoir. This understanding can be obtained from the analysis of results of down-hole tests and laboratory measurements. One of the properties that can be measured is the magnetic behaviour of the reservoir fluids and mineral scales. The build-up of scale is an important process in oil and gas reservoirs, and can have a damaging effect on the flow of fluid in reservoir rocks and in wells. An understanding of the magnetic properties of fluids such as brines, crude oils, brines with a scaling tendency, brines containing scale inhibitors, and of scale minerals is a key objective of this research. These magnetic techniques have the advantage of being environmentally neutral, nondestructive, rapid and low cost (Potter 2005). Understanding of the magnetic properties of the petroleum reservoir matrix rock may provide new techniques for improved reservoir characterisation, petroleum exploration and production. Magnetic susceptibility measurements of brines, crude oils and scale inhibitors have been carried out and are reported in this thesis. All fluids are diamagnetic, with distinct differences between them. The magnetic susceptibility values for brines are related to their solute composition, while for crude oils the magnetic susceptibility values are related to their physical and chemical properties. The effect of solute composition and concentration on the magnetic susceptibility of a brine is also measured. Measuring the magnetic susceptibility of a produced water sample would allow rapid detection of injection water breakthrough at the production facilities, and therefore iii improve the prospect of quickly deploying a preventative or remedial action to mitigate the risk of inorganic scale damage in the production system. The proposed method described herein introduces the potential for either an in line system, or at least an immediate analysis of the sample when captured, thus allowing operators to make important scale management decisions much earlier than is currently possible. Magnetic hysteresis measurements of reservoir scale minerals could be used as a rapid, non-destructive method to characterise and indentify the types of scale minerals occurring (diamagnetic, paramagnetic, ferromagnetic and antiferromagnetic). Changes in the slope (the magnetic susceptibility) of the hysteresis curves may be used to identify different scale minerals. Straight lines with negative slope are due to diamagnetic minerals, whilst straight lines with positive slope are due to paramagnetic minerals. The relative amounts of diamagnetic and paramagnetic minerals contained in a mixture of the two can potentially be quantified by the slope of the straight line at high fields.

Available in PDF, EPUB and Kindle. Book excerpt: The second revised edition of the Encyclopedia of Quaternary Science, Four Volume Set, provides both students and professionals with an up-to-date reference work on this important and highly varied area of research. There are lots of new articles, and many of the articles that appeared in the first edition have been updated to reflect advances in knowledge since 2006, when the original articles were written. The second edition will contain about 375 articles, written by leading experts around the world. This major reference work is richly illustrated with more than 3,000 illustrations, most of them in colour. Research in the Quaternary sciences has advanced greatly in the last 10 years, especially since topics like global climate change, geologic hazards and soil erosion were put high on the political agenda. This second edition builds upon its award-winning predecessor to provide the reader assured quality along with essential updated coverage Contains 357 broad-ranging articles (4310 pages) written at a level that allows undergraduate students to understand the material, while providing active researchers with a ready reference resource for information in the field. Facilitates teaching and learning The first edition was regarded by many as the most significant single overview of Quaternary science ever, yet Editor-in-Chief, Scott Elias, has managed to surpass that in this second edition by securing even more expert reviews whilst retaining his renowned editorial consistency that enables readers to navigates seamlessly from one unfamiliar topic to the next

Book excerpt: Magnetism is important in environmental studies for several reasons, the two most fundamental being that most substances exhibit some form of magnetic behavior, and that iron is one of the most common elements in the Earth's crust. Once sequestered in a suitable material, magnetic particles constitute a natural archive of conditions existing in former times. Magnetism provides a tracer of paleo-climatic and paleo-environmental conditions and processes.Environmental Magnetism details the occurrence and uses of magnetic materials in the natural environment. The first half of the volume describes the basic principles. The second half discusses the applications of magnetic measurements in various environmental settings on land, in lakes, in the ocean, and even various biological organisms.* Material is broadly applicable to environmental studies* Case histories illustrate key points* Extensive bibliography makes further research quick and easy
