Book Description

The analysis of materials containing several elements used to be a difficult problem for analytical chemists, so a well established sequence of wet chemical qualitative tests were performed to ensure each element was detected. Quantitative tests could then be carried out on the sample, according to the range of elements present. Most analytical chemists were very familiar with these techniques, having been taugth them from a very early stage in their education and careers. The analytical chemist can now call on a range of specialist instrumental techniques which can detect the presence of many elements, often simultaneously, and often quantitatively, providing rapid results on samples which, in the past, could take days. The drawback is that the instruments tend to be expensive, suited to particular sample types or matrices and complex in both setting up and in the interpretation of results. Furthermore the general analytical chemist may have access and familiarity with only one or two methods.Written by an international team of contributors, each experts in their particular fields, this book familiarizes analytical chemists with the range of elemental analysis techniquers, to enable them to specify the most appropriate test for any given sample. In addition, it contains important chapters on sample preparation and quality control, essential elements in obtaining accurate and reliable analytical results. As such, this book will be essential reading for all analytical chemists. The techniques of elemental analysis are important in many other disciplines, so the book will be of particular interest to those commissioning a wide range of analytical measurements, such as chemists, geologists, environmental scientists and biologists. The breadth and depth of coverage will also make the book very useful for advanced students. ... Read more

Book Description

Researchers in geomorphology, geochemistry, Quaternary geology, soil science, and mineralogy will welcome this volume, the first to focus exclusively on rates of silicate chemical weathering.Consisting largely of previously unpublished data from six countries, the volume examines the latest experimental, modelling, and field results.****New information is presented on topics of current research interest, including inferences about chemical mechanisms at the level of mineral surfaces, and data relating weathering rates to landscape evolution over millions of years.The volume integrates the variety of approaches used by diverse subdisciplines in the assessment of weathering rates, and provides up-to-date references. ...

Book Description

This newly published book is an organized collection of papers dealing with changes in the quality of water as it moves through the world's hydrologic cycle-from the sea, lakes, and rivers-to its hydrosphere and then back to earth as precipitation, where the water again percolates through the soil or falls on the ocean, rivers, or lakes. (Changes that occur are physical, chemical, and biological.) Though chapters discuss results of specific lab or field experiments which in themselves have value for the scientist, focus is on processes involved. Many general concepts of water quality are provided in this cohesively organized book. ... Read more

Book Description

This is the first book entirely devoted to travertine, a material in use for over 4000 years. The single-author work is a valuable reference source for travertine, covering all aspects of travertine origins, formation, composition, flora and fauna, occurrence and utilisation, as well as covering allied continental carbonates such as lake marls, calcretes and beachrocks.
Travertine, some forms of which are often known as ‘tufa’, is of particular significance as a source of environmental information (fossils and isotope geochemistry), often permitting the reconstruction of past environments. Reviews of dating techniques, classification and geomorphology are included and the author attempts to provide an unbiased but critical appraisal of current models of travertine formation.
Currently, travertine is in great demand as a building and ornamental stone. It has also been exploited in unconventional ways, such as ‘petrifying springs’ and by way of unusual and little known artistic techniques. Scaling of pipes and boilers is often the result of processes allied to travertine formation. The phenomenon is described parallel to  methods of scale elimination and compared with natural processes where travertine formation is inhibited. Travertine sites are of special scientific interest, with their rich and often unique floras and faunas displaying their unique biodiversity, and their unusual and often fragile biota. Conservation issues are discussed, together with the description of travertine fossils and occurrences throughout the geological record.
The content will be of interest to carbonate sedimentologists, hydrobiologists, palaeoclimatologists, physical geographers, water treatment engineers, astrobiologists, architects, and sculptors.

Book Description

A knowledge of crystallography opens the door to a clearer understanding of topics in physics, chemistry, and other disciplines. In this new text, basic ideas in crystallography and diffraction are explained simply and comprehensively. The physical concepts and geometrical features common to diffraction modes are emphasized by simple analogies and demonstrations, with special attention paid to two-dimensional patterns and symmetry. The book, written by an experienced teacher, is an ideal introduction for students. ... Read more

Highly recommended.
Very nice book, very comprehensive, excellent quality of pictures. Can be recommended as a very gentle introduction to crystallography and diffraction. Probably not so useful for more advanced students. ... Read more

From the supplier: The CHEMFORM program converts geochemical data files to formats read by the U.S. Geological Survey (USGS) family of codes namely: WATEQ4F, PHREEQE and NETPATH. The program can also convert data from one USGS code to another and performs database functions for files in the NETPATH format. The program is available on a single high-density diskette and requires 480K of free memory.

Book Description

The dynamic, evolving Earth, and the mathematical representation of its geochemical changes are the subject of this timely, helpful handbook. Global warming, changes in the ocean, and the effects of fossil fuel combustion are just a few of the phenomena that make the development of geochemical models critical. But what computational methods will help to accurately carry out this task? This new text teaches the methodology of computational simulation of environmental change. The author presents interesting applications of his methods to describe the response of the ocean and atmosphere to the infusion of pollutants, the effect of evaporation on seawater composition, climate change, and many other aspects of the Earth's evolving ecosystem. He also presents simple approaches for solving non-linear systems, calculating isotope ratios, and dealing with chains of identical reservoirs. With creative programs that can be executed on any personal computer, Walker offers earth scientists the techniques necessary to address the key problems in their field. ... Read more
