This book was released on 2005 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: [Truncated] A major challenge in modern mineral exploration is to identify critical relationships between geological characteristics and economically significant mineral deposits, and to apply these in conceptual targeting. With increasingly global exploration, it is important that GIS tools for prospectivity analysis apply to all scales of exploration from global, craton, regional to local. This allows spatial controls of mineralisation to be better defined, at these scales and hence improve our exploration criteria. To achieve this, a number of parameters have to be integrated to produce the best targeting methodology for each scale. This study examines the effectiveness of a variety of GIS methods and exploration criteria for orogenic gold at different scales. The geological features used to estimate prospectivity were identified using a new approach to modelling GIS fuzzy membership functions and economic deposit target sizes to create and test input GIS layers. This approach was found to be effective for global- to regional-scale targeting strategies, where sufficient numbers of deposits are available for statistical analysis of spatial relationships between geological map features and sites of known deposits. This study resulted in the development of; 1) a robust measure of the strength of GIS input layers based on both deposit frequency and total contained gold (TCG), 2) a methodology for incorporating economic criteria e.g., 31 t TCG (1 Moz Au) in the conversion of raw data to fuzzy membership values for GIS input layers, 3) an approach to identifying the relationship between the size of gold deposits at a regional-scale, based on a variety of GIS deposit layers, i.e., a) all deposits (dep-all), b) deposits 6 t TCG (dep-min), c) deposits 6 t TCG, with deposits > 31 t TCG reduced to 31 t TCG (dep-cut), d) deposits > 18 t TCG (dep- max), 4) an improved method of calculating the capture efficiency ratios that quantifythe predictive power of candidate fuzzy membership GIS input layers, and 5) abinominal statistical test to determine confidence levels for the significance of spatial relationships based on both deposit frequency and TCG.

Book Synopsis Geochemical Anomaly and Mineral Prospectivity Mapping in GIS by : E.J.M. Carranza
Download or read book Geochemical Anomaly and Mineral Prospectivity Mapping in GIS written by E.J.M. Carranza and published by Elsevier. This book was released on 2008-11-26 with total page 365 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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

Book Synopsis Statistical Models for Optimizing Mineral Exploration by : J.G. De Geoffroy

This book was released on 2012-12-06 with total page 443 pages. Available in PDF, EPUB and Kindle. Book excerpt: After the spectacular successes of the 1960's and 1970's, the mineral exploration business is at a crossroads, facing uncertain t:imes in the decades ahead. This situation requires a re-thinking of the philosophy guiding mineral exploration if it is to emulate its recent performance. The ma:i. n argument of a previous volume titled "Designing Opt:lmal Strategies for Mineral Exploration", published in 1985 by Plenum Publishing Corporation of New York, is that a possible answer to the challenge facing mineral explorationists lies in the philosophy of opt:irn1zation. This new approach should help exploration staff make the best achievable use of the sophisticated and costly technology which is presently available for the detection of ore deposits. The main emphasis of the present volume is placed on the mathematical and computational aspects of the opt:irn1zation of mineral exploration. The seven chapters making up the ma:i. n body of the book are devoted to the description and application of various types of computerized geomathematical models which underpin the optimization of the mineral exploration sequence. The topics covered include: (a) the opt:lmal selection of ore deposit types and regions of search, as well as prospecting areas within the regions (Chapters 2, 3, 4, 6), (b) the designing of airborne and ground field programs for the opt:lmal coverage of prospecting areas (Chapters 2, 3, 4), (c) delineation and evaluation of exploration targets within prospecting areas by means of opt:irn1zed models (Chapter 5).

Available in PDF, EPUB and Kindle. Book excerpt: Few knowledgeable people would deny that the field of mineral exploration is facing some difficult times in the foreseeable future. Among the woes, we can cite a worldwide economic uneasiness reflected by sluggish and at times widely fluctuating metal prices, global financial uncertainties, and relentless pressures on costs despite a substantial slowing down of the rate of inflation. Furthermore, management is forced to tum to more sophisticated and expensive technologies and to look farther afield to more remote regions, as the better quality and more easily accessible ore deposits have now been revealed. This rather gloomy outlook should persuade explorationists to cast about for a new philosophy with which to guide mineral exploration through the challenging decades ahead. Once already, in the early 1960s, a call for change had been heard (Ref. 30 in Chapter 1), when it became obvious that the prospecting methods of yesteryear, so successful in the past, could not keep up with the rapidly growing demand for minerals of the postwar period. The answer, a massive introduction of sophisticated geophysical and geochemical technologies backed by new geo logical models, proved spectacularly successful throughout the 1960s and the 1970s. But for both economic and technological reasons, the brisk pace of the last two decades has considerably slowed down in the early 1980s, as if a new threshold has been reached.

This book was released on 1991 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Groups and individuals concerned with the search for mineral deposits use a great deal of information with high spatial content to generate prospecting targets. The information is commonly in the form of maps and may be subjected to a variety of qualitative and quantitative techniques of map analysis, the objective of which is to avoid mindless wandering in the field by reducing the exploration area while retaining a high potential for success. Geographic information systems are of great interest as a means of managing map-based information. The systems are used in government but costs and complexity are slowing their acceptance in the for-profit sector. This research demonstrates low-cost software on a widely available computer system to explore five alternative methods of applying a geographic information system to the problem of generating prospecting targets. The methodology could be applied equally well to defining targets of other kinds, from sites for toxic waste disposal to candidates for mass marketing. Success of the applications is measured by their ability to reduce the exploration area while retaining a high proportion of the known mineral deposits that provide an estimate of the undiscovered deposits. Area reductions range from zero percent, a worst case, to 98%; retentions of known deposits range from 100% to 29%. Efficiency, a ratio of the area containing known deposits within the favorable area to the entire favorable area, is introduced as a comparative measure of success. The most efficient approach is more than 40 times as efficient as the least efficient. Two of the approaches demonstrated are new, and provide a formal approach to map analysis. The research demonstrates the utility and flexibility of a low-cost, raster-format geographic information system in a pioneer application to the east half of the Tucson quadrangle, an area of over 10,000 square kilometers.
