Practical Geochemistry

Practical Geochemistry PDF Author: Paul Alexandre
Publisher: Springer Nature
ISBN: 3030724530
Category : Science
Languages : en
Pages : 124

Book Description
This book is a marked departure from typical introductory geochemistry books available: It provides a simple, straightforward, applied, and down-to-earth no-nonsense introduction to geochemistry. It is for the undergraduate students who are introduced to the subject for the first time, but also for practicing geologists who do not need the heavy-duty theory, but some clear, simple, and useful practical tips and pointers. This book, written from the point of view of a practicing geologist, introduces the fundamental and most relevant principles of geochemistry, explaining them whenever possible in plain terms. Crucially, this textbook covers – in a single volume! – practical and useful topics that other introductory geochemistry books ignore, such as sampling and sample treatment, analytical geochemistry, data treatment and geostatistics, classification and discrimination diagrams, geochemical exploration, and environmental geochemistry. The main strengths of this book are the breadth of useful and practical topics, the straightforward and approachable way in which it is written, the numerous real-world and specific geological examples, and the exercises and review questions (using real-world data and providing on-line answers). It is therefore easily understood by the beginner geochemist or any geologist who desires to use geochemistry in their daily work.

Geochemical Anomaly and Mineral Prospectivity Mapping in GIS

Geochemical Anomaly and Mineral Prospectivity Mapping in GIS PDF Author: E.J.M. Carranza
Publisher: Elsevier
ISBN: 008093031X
Category : Science
Languages : en
Pages : 365

Book Description
Geochemical Anomaly and Mineral Prospectivity Mapping in GIS documents and explains, in three parts, geochemical anomaly and mineral prospectivity mapping by using a geographic information system (GIS). Part I reviews and couples the concepts of (a) mapping geochemical anomalies and mineral prospectivity and (b) spatial data models, management and operations in a GIS. Part II demonstrates GIS-aided and GIS-based techniques for analysis of robust thresholds in mapping of geochemical anomalies. Part III explains GIS-aided and GIS-based techniques for spatial data analysis and geo-information sybthesis for conceptual and predictive modeling of mineral prospectivity. Because methods of geochemical anomaly mapping and mineral potential mapping are highly specialized yet diverse, the book explains only methods in which GIS plays an important role. The book avoids using language and functional organization of particular commercial GIS software, but explains, where necessary, GIS functionality and spatial data structures appropriate to problems in geochemical anomaly mapping and mineral potential mapping. Because GIS-based methods of spatial data analysis and spatial data integration are quantitative, which can be complicated to non-numerate readers, the book simplifies explanations of mathematical concepts and their applications so that the methods demonstrated would be useful to professional geoscientists, to mineral explorationists and to research students in fields that involve analysis and integration of maps or spatial datasets. The book provides adequate illustrations for more thorough explanation of the various concepts. - Explains GIS functionality and spatial data structures appropriate regardless of the particular GIS software in use - Simplifies explanation of mathematical concepts and application - Illustrated for more thorough explanation of concepts

Groundwater Geochemistry

Groundwater Geochemistry PDF Author: Broder J. Merkel
Publisher: Springer Science & Business Media
ISBN: 3540746684
Category : Science
Languages : en
Pages : 230

Book Description
To understand hydrochemistry and to analyze natural as well as man-made impacts on aquatic systems, hydrogeochemical models have been used since the 1960’s and more frequently in recent times. Numerical groundwater flow, transport, and geochemical models are important tools besides classical deterministic and analytical approaches. Solving complex linear or non-linear systems of equations, commonly with hundreds of unknown parameters, is a routine task for a PC. Modeling hydrogeochemical processes requires a detailed and accurate water analysis, as well as thermodynamic and kinetic data as input. Thermodynamic data, such as complex formation constants and solubility-products, are often provided as databases within the respective programs. However, the description of surface-controlled reactions (sorption, cation exchange, surface complexation) and kinetically controlled reactions requires additional input data. Unlike groundwater flow and transport models, thermodynamic models, in principal, do not need any calibration. However, considering surface-controlled or kinetically controlled reaction models might be subject to calibration. Typical problems for the application of geochemical models are: • speciation • determination of saturation indices • adjustment of equilibria/disequilibria for minerals or gases • mixing of different waters • modeling the effects of temperature • stoichiometric reactions (e.g. titration) • reactions with solids, fluids, and gaseous phases (in open and closed systems) • sorption (cation exchange, surface complexation) • inverse modeling • kinetically controlled reactions • reactive transport Hydrogeochemical models depend on the quality of the chemical analysis, the boundary conditions presumed by the program, theoretical concepts (e.g.
