Summary:

Nowadays, mapping of geochemical anomalies and/or prospective areas involves stacking digital geochemical and geological maps on top of each other on an electronic light table (i.e., by using a GIS or geographic information system). This volume documents, surveys and demonstrates various GIS-aided and/or GIS-based techniques for mapping of geochemical anomalies and prospective areas in the target generation phase of mineral exploration. It consists of three parts, all centred on the theme predictive modeling or mapping. 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 synthesis for conceptual and predictive modeling of mineral prospectivity. This volume is intended to be an instructional textbook and general reference manual for exploration geochemists and/or exploration geologists, who are enthusiastic and already possess skills in applying GIS or who are interested in applying GIS. It is also hoped that geoscience academics and graduate students not only in the knowledge fields of geo-resource exploration but also in the knowledge fields of geohazard mapping and/or geo-environmental characterisation would find the concepts and methods described in this volume useful in their work.
