Geochemical Anomaly And Mineral Prospectivity Mapping In Gis

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

Excerpt from the review of Remote Sensing Geology (2nd ed., 2003): International Journal of Applied Earth Observation and Geoinformation, 5 (2004) 239–240 “....Graduate students, research workers and professional earth scientists will use this book to their advantage and with pleasure; it is well-written, to the point and with an emphasis on understanding the principles underlying this wide spectre of technology in its application to the earth sciences. Remote sensing is a fascinating subject; so is geology. The author has fully succeeded in providing a fascinating book that combines them in a handy volume.” Jan J. Nossin

This book provides a wealth of geomathematical case history studies performed by the author during his career at the Ministry of Natural Resources Canada, Geological Survey of Canada (NRCan-GSC). Several of the techniques newly developed by the author and colleagues that are described in this book have become widely adopted, not only for further research by geomathematical colleagues, but by government organizations and industry worldwide. These include Weights-of-Evidence modelling, mineral resource estimation technology, trend surface analysis, automatic stratigraphic correlation and nonlinear geochemical exploration methods. The author has developed maximum likelihood methodology and spline-fitting techniques for the construction of the international numerical geologic timescale. He has introduced the application of new theory of fractals and multi fractals in the geostatistical evaluation of regional mineral resources and ore reserves and to study the spatial distribution of metals in rocks. The book also contains sections deemed important by the author but that have not been widely adopted because they require further research. These include the geometry of preferred orientations of contours and edge effects on maps, time series analysis of Quaternary retreating ice sheet related sedimentary data, estimation of first and last appearances of fossil taxa from frequency distributions of their observed first and last occurrences, tectonic reactivation along pre-existing schistosity planes in fold belts, use of the grouped jackknife method for bias reduction in geometrical extrapolations and new applications of the theory of permanent, volume-independent frequency distributions.

In the late 18th century, Neptunists and Plutonists had controversial opinions about the formation of the Earth and its lithological units. The former believed that rocks formed from the crystallization of minerals in the early Earth’s oceans, the latter believed that rocks were formed in fire. Both theories ignored the importance of continuous water-rock interaction processes at Earth ́s surface and underground, which can enhance and define the type of volcanic activity, can cause the formation of secondary hydrothermal minerals and respective ore deposits, or simply alter the natural landscape by weathering. Although not visible at first glance, water-rock interaction plays a significant role in the daily life of humans. Many primary necessities of modern society, such as the availability of high-quality drinking water, the supply of fossil fuel and renewable energy types, the abundance of precious minerals, the remediation of contaminated natural sites, and the reconnaissance of geological hazards require a profound understanding of physicochemical processes interacting between liquid, solid and gas phases. Since 1974, when the first Water-Rock Interaction Symposia (WRI-1) was held in Prague (Czechoslovakia, now the Czech Republic), the Working Group on Water-Rock Interaction of the International Association of GeoChemistry (IAGC) has organized an international meeting every three years to present and discuss the most recent results in geochemical technologies. In 2010, WRI-13 attracted about 300 geoscientists affiliated with universities, research institutions, regulatory agencies and from private industry, from 35 countries to Guanajuato, Mexico. The 231 papers published in this volume describe novel advances in research related to interactive processes between the hydrosphere and the lithosphere. Innovative field-based studies, theoretical approaches and small-scale lab experiments are applied to reconstruct and combine pieces of the complex hydrological puzzle, and to confront society ́s impact on the environment. The papers reveal details on high-temperature reactions during the formation of hydrothermal ore deposits and geothermal reservoirs, practical case studies on groundwater quality and karst systems, environmental issues by mine tailings, novel technologies for the attenuation and remediation of contaminated sites, water/mineral interfacial processes on a micro- to macroscopic scale, the kinetics of weathering during low temperature conditions, examples for the advanced modeling of flow and transport processes as well as for CO2 reservoir injection, biochemical factors in surface and underground media, and the application of novel isotope techniques in rock/water/gas systems. Special emphasis in many papers is given on environmental concerns in abandoned mining districts, the occurrence and hazards of non-metals (especially arsenic) in exploited groundwater systems, and an increasing interest in mitigating CO2 emission by its injection into underground reservoirs. The papers in this volume are of wide-ranging interest to professionals and students in Earth sciences, including geochemistry, hydrochemistry, hydrology, geology, mineralogy, volcanology and environmental sciences, but also to decision-makers and engineers involved in the management of energy and natural resources, as well as professionals concerned about environmental issues.
