Available in PDF, EPUB and Kindle. Book excerpt: "From 2008 to 2013, the Canadian government is investing in a major initiative termed Geo-mapping for Energy and Minerals. The objectives of this program are to stimulate economic development in northern Canada and to diversify the economy of northern communities by providing new geoscientific data on energy and mineral potential. These objectives have led to the implementation of numerous projects by the Geological Survey of Canada (GSC), conducted in collaboration with territorial and provincial geological surveys as well as students enrolled in graduate programs. Several of these projects involve a surficial geology component and the sampling of till. As a first step towards the development of consistent methodologies for the GSC's GEM projects that include till sampling activities, a working group of Quaternary scientists from the Northern Canada Division has prepared this protocol manual. The purpose of the protocols presented in this manual is not to restrict development of or experimentation with new methodologies but rather to ensure that projects use common methods for sample collection, preparation and analysis as a minimum. These protocols will ultimately allow comparison of data sets separated by large distances and gathered through the course of different projects. Hopefully, the protocols presented herein will be adopted in future programs with objectives similar to GEM. However, adaptation and modification of these protocols will be required as technological developments continue and new ideas and concepts are put forward"--Introd., p. 1, 2.

Download or read book Geochemistry of European Bottled Water written by Clemens Reimann and published by . This book was released on 2010 with total page 268 pages. Available in PDF, EPUB and Kindle. Book excerpt: In Europe, ca. 1900 "mineral water" brandsare officially registered and bottled for drinking. Bottled waters isgroundwater and is in large parts of the continent rapidly developing into themain supply of drinking water for the general population.This book is the first state of the art overview of the chemistry ofgroundwaters from 40 European countries from Portugal to Russia, measured on1785 bottled water samples, equivalent to 1189 distinct bottled water brandsfrom 1247 wells in 884 locations plus an additional 500 tap water samplesacquired in 2008 by the network of EuroGeoSurveys experts all across Europe.In contrast to previously available compilations, all chemical data (containedon the enclosed CD) were measured in a single laboratory, under strict qualitycontrol with high internal and external reproducibility, affording a singlehigh quality, internally consistent dataset. More than 70 parameters weredetermined on every sample using state of the art analytical techniques withultra low detection limits (ICPMS, ICPOES, IC) at a single hydrochemical labfacility. Because of the wide geographical distributionof the water sources across 40 European countries, the bottled mineral,drinking and tap waters characterized herein may be used for obtaining a firstestimate of "ground- water geochemistry" at the scale of the EuropeanContinent, previously unavailable in this completeness, quality and coverage.The data published here allow for the first time to present a comprehensiveinternally consistent, overview of the natural distribution and variation ofthe determined chemical elements and additional state parameters of groundwaterat the European scale. Most elements show a very widerange, usually 3 to 4 but up to 7 orders of magnitude, of natural variation of their concentration. Data are interpreted in terms of their origin, considering hydrochemical parameters, such as the influence of soil, vegetation cover and mixing with deep waters, as well as other factors (bottling effects, leaching from bottles). A chapter is devoted to comparing the results from the bottled waters with those of European tap waters and previously published datasets. The authors also provide an overview of the legal framework, that any bottled water sold in the European Union must comply with. It provides a comprehensive compilation of current drinking water action levels in European countries, limiting values of the European Drinking/Mineral/Natural Mineral Water directives (1998/83/EC, 2003/40/EC, 2009/54/EC) and legislation in effect in 26 individual European Countries, and for comparison those of the FAO and in effect in the US (EPA, maximum contaminant levels [MCA]). The accompanying CD contains the extensive data sets, sample data (of 1189 different brands) and two previously published European water chemistry data sets.

This book was released on 2023 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Regional-scale lake sediment surveys have been successfully used since the 1970s as a means for reconnaissance geochemical exploration. Lake sediment sampling is typically performed in areas with a lack of streams and an overabundance of small-sized (≤5 km across) lakes. Lake sediments are known to have major, minor and trace element concentrations that reflect the local geology. Overall, surveys are planned and conducted following four distinct stages: 1) background research, 2) orientation survey, 3) regional survey, and 4) detailed survey. At the Geological Survey of Canada, samples are usually collected from a helicopter with floats. Sample density ranges from 1 sample per 6 to 13 km2. Samples are collected from the centre of the lake using a gravity torpedo sampler which corresponds to a hollow-pipe, butterfly bottom-valved sampler attached by a rope to the helicopter. Collected sediment samples are then placed in labelled bags and left to air dry. Detailed field notes and additional samples (field duplicates), for the purpose of a quality assurance and quality control program, are also taken. Samples are then milled and sent to analytical laboratories for element determination. Commonly used analytical methods include: X-ray fluorescence (XRF), atomic absorption spectroscopy (AAS), inductively coupled plasma-atomic emission spectrometry (ICP-AES) and -mass spectrometry (ICP-MS), instrumental neutron activation analysis (INAA), and/or determination of volatile compounds and organic carbon using Loss on Ignition (LOI). Analytical data is first evaluated for quality (contamination, accuracy and precision). Numerous options for the analysis of lake sediment data exist, ranging from simple basic element concentration maps and statistical graphical displays with summary statistics, to employing multivariate and machine learning methodologies. By adopting the set of guidelines and examples presented in this report, scientific researchers, exploration geologists, geochemists and citizen scientists will be able to directly compare lake sediment datasets from anywhere in Canada"--Abstract, page 3.

This book was released on 2012-12-06 with total page 419 pages. Available in PDF, EPUB and Kindle. Book excerpt: How large is the natural variation in concentration of the various elements in different media? How do the oft-cited "World average concentrations" in different media compare with actual analytical data? How low a detection limit do I need to attain if I want to analyse for an element in soils, sediments, water or plants? All these questions and many more can be answered by using this unique reference book. It collates data on the most important properties and uses of all naturally occurring chemical elements. It combines these with data obtained from actual analyses of different sample media (soil, stream sediment, stream water, ground water, plants, human body fluids). This combination of facts and actual data makes this book suitable for learning and teaching applied geochemistry as well.

Download or read book Biogeochemistry in Mineral Exploration written by Colin E. Dunn and published by Elsevier. This book was released on 2011-08-30 with total page 481 pages. Available in PDF, EPUB and Kindle. Book excerpt: Significant refinements of biogeochemical methods applied to mineral exploration have been made during more than twenty years since the last major publication on this technique. This innovative, practical and comprehensive text is designed as a field handbook and an office reference volume. It outlines the historical development of biogeochemical methods applied to mineral exploration, and provides details of what, how, why and when to collect samples from all major climatic environments with examples from around the world. Recent commercialization of sophisticated analytical technology permits immensely more insight into the multi-element composition of plants. In particular, precise determination of ultra-trace levels of ‘pathfinder’ elements in dry tissues and recognition of element distribution patterns with respect to concealed mineralization. Data handling and interpretation are discussed in context of a wealth of previously unpublished information, including a section on plant mineralogy, much of which has been classified as confidential until recently. Data are provided on the biogeochemistry of more than 60 elements and, by case history examples, their roles discussed in assisting in the discovery of concealed mineral deposits. A look to the future includes the potential role of bacteria to provide new focus for mineral exploration. Describes the practical aspects of plant selection and collection in different environments around the world, and how to process and analyze them Discusses more than 60 elements in plants, with data interpretation and case history results that include exploration for Au, PGEs, U, base metals and kimberlites
