Book excerpt: The objective of this study is to detect the presence of anthropogenic magnetic particles by measuring the magnetic signature of soil samples in Baton Rouge, LA. Baton Rouge is currently ranked third among the United States' most polluted cities, so it is necessary to locate the sources of the problem and find solutions (U.S. Environmental Protection Agency [EPA], 2014). Magnetic susceptibility is a property that is easily, quickly, and inexpensively determined. It provides a highly-sensitive measurement of the compositional changes of minerals in soil. Magnetic susceptibility is influenced both anthropogenically and naturally by lithological and pedological heavy metal content. In this study, roughly 260 km2 (110 mi2) were sampled within the Baton Rouge, Louisiana area, and multiple environmental settings were covered. Geospatial and x-ray fluorescence analysis (XRF) were used to correlate magnetic susceptibility measurements and indicate increased anthropogenic activity near major industrial areas and interstates. Soil samples were analyzed, and isothermal remanent magnetization (IRM) acquisition curves indicate the presence of high- and low coercivity minerals, presumably magnetite and hematite. Enhanced susceptibility measurements do not appear to be dominated by lithology or soil in this particular area.

This book was released on 2004 with total page 6 pages. Available in PDF, EPUB and Kindle. Book excerpt: Detection and discrimination of unexploded ordnance (UXO) and landmines with total field magnetic and electromagnetic induction (EMI) sensors can be severely inhibited by large variations in background magnetic susceptibility. Sites in Hawaii, USA, and similar settings have very high magnetic susceptibility over the entire site due to the basaltic soils. The basaltic soils exhibit magnetic viscosity, which is frequency dependence of the magnetic susceptibility. This makes detection of UXO or landmines difficult. There are current efforts to model the influence of magnetic susceptibility variations on geophysical data. A different situation exists at sites such as Jefferson Proving Ground, IN, USA, where sections of the site exhibit variations in magnetic susceptibility that are of the same spatial wavelength and amplitude as the target UXO or landmines. The JPG soils do not exhibit magnetic viscosity. We have collected total magnetic field data over several grids as well as lines of magnetic susceptibility data with two instruments and at three frequencies over several of the anomalous regions. We have also collected soil samples at three depths at stations along these lines and measured their magnetic susceptibilities in the lab at two frequencies. We have found a correlation between the surface geology, topography, and magnetic susceptibility measurements. Also, the variations in magnetic susceptibility with depth are a function of the variable weathering and mineral transport due to surface water runoff through the areas of lower elevation. We are currently developing a laboratory measurement system to measure magnetic susceptibility at discrete frequencies from 30 Hz to 100 kHz. This capability will allow us to model the various EMI measurement systems currently in use and filter the background magnetic susceptibility variations.

Available in PDF, EPUB and Kindle. Book excerpt: This book honors the career of Professor Elizabeth Gierlowski-Kordesch who was a pioneer and leader in the field of limnogeology since the 1980s. Her work was instrumental in guiding students and professionals in the field until her untimely death in 2016. This collection of chapters was written by her colleagues and students and recognize the important role that Professor Gierlowski-Kordesch had in advancing the field of limnogeology. The chapters show the breadth of her reach as these have been contributed from virtually every continent. This book will be a primary reference for scientists, professionals and graduate students who are interested in the latest advances in limnogeologic processes and basin descriptions in North and South America, Europe, Africa, and China. *Free supplementary material available online for chapters 3,11,12 and 13.

This book was released on 2010-10-17 with total page 244 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since the 1960s, x-ray fluorescence spectrometry (XRF), both wavelength and energy-dispersive have served as the workhorse for non-destructive and destructive analyses of archaeological materials. Recently eclipsed by other instrumentation such as LA-ICP-MS, XRF remains the mainstay of non-destructive chemical analyses in archaeology, particularly for volcanic rocks, and most particularly for obsidian. In a world where heritage and repatriation issues drive archaeological method and theory, XRF remains an important tool for understanding the human past, and will remain so for decades to come. Currently, there is no comprehensive book in XRF applications in archaeology at a time when the applications of portable XRF and desktop XRF instrumentation are exploding particularly in anthropology and archaeology departments worldwide. The contributors to this volume are the experts in the field, and most are at the forefront of the newest applications of XRF to archaeological problems. It covers all relevant aspects of the field for those using the newest XRF technologies to deal with very current issues in archaeology.
Download or read book Environmental Magnetism written by Mark Evans and published by Elsevier. This book was released on 2003-06-23 with total page 318 pages. Available in PDF, EPUB and Kindle. 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
Download or read book Characterization of Solid Surfaces written by Philip F. Kane and published by Springer Science & Business Media. This book was released on 2013-11-27 with total page 675 pages. Available in PDF, EPUB and Kindle. Book excerpt: Until comparatively recently, trace analysis techniques were in general directed toward the determination of impurities in bulk materials. Methods were developed for very high relative sensitivity, and the values determined were average values. Sampling procedures were devised which eliminated the so-called sampling error. However, in the last decade or so, a number of developments have shown that, for many purposes, the distribution of defects within a material can confer important new properties on the material. Perhaps the most striking example of this is given by semiconductors; a whole new industry has emerged in barely twenty years based entirely on the controlled distribu tion of defects within what a few years before would have been regarded as a pure, homogeneous crystal. Other examples exist in biochemistry, metallurgy, polyiners and, of course, catalysis. In addition to this of the importance of distribution, there has also been a recognition growing awareness that physical defects are as important as chemical defects. (We are, of course, using the word defect to imply some dis continuity in the material, and not in any derogatory sense. ) This broadening of the field of interest led the Materials Advisory Board( I} to recommend a new definition for the discipline, "Materials Character ization," to encompass this wider concept of the determination of the structure and composition of materials. In characterizing a material, perhaps the most important special area of interest is the surface.
