EBOOK SYNOPSIS:

When some useful information is hidden behind a mass of unwanted information we often resort to information processing used in its broad sense or specifically to signal processing when the useful information is a waveform. In geophysical surveys, in particular in aeromagnetic and gravity surveys, from the measured field it is often difficult to say much about any one specific target unless it is close to the surface and well isolated from the rest. The digital signal processing approach would enable us to bring out the underlying model of the source, that is, the geological structure. Some of the tools of dsp such as digital filtering, spectrum estimation, inversion, etc., have found extensive applications in aeromagnetic and gravity map analysis. There are other emerging applications of dsp in the area of inverse filtering, three dimensional visualization, etc. The purpose of this book is to bring numerous tools of dsp to the geophysical community, in particular, to those who are entering the geophysical profession. Also the practicing geophysicists, involved in the aeromagnetic and gravity data analysis, using the commercially available software packages, will find this book useful in answering their questions on "why and how?". It is hoped that such a background would enable the practising geophysicists to appreciate the prospects and limitations of the dsp in extracting useful information from the potential field maps. The topics covered are: potential field signals and models, digital filtering in two dimensions, spectrum estimation and application, parameter estimation with error bounds.

ISBN:
Available Language: English, Spanish, And French
EBOOK SYNOPSIS:

In this book the author presents the state-of-the-art electromagnetic (EM) theories and methods employed in EM geophysical exploration. The book brings together the fundamental theory of EM fields and the practical aspects of EM exploration for mineral and energy resources. This text is unique in its breadth and completeness in providing an overview of EM geophysical exploration technology. The book is divided into four parts covering the foundations of EM field theory and its applications, and emerging geophysical methods. Part I is an introduction to the field theory required for baseline understanding. Part II is an overview of all the basic elements of geophysical EM theory, from Maxwell's fundamental equations to modern methods of modeling the EM field in complex 3-D geoelectrical formations. Part III deals with the regularized solution of ill-posed inverse electromagnetic problems, the multidimensional migration and imaging of electromagnetic data, and general interpretation techniques. Part IV describes major geophysical electromagnetic methods—direct current (DC), induced polarization (IP), magnetotelluric (MT), and controlled-source electromagnetic (CSEM) methods—and covers different applications of EM methods in exploration geophysics, including minerals and HC exploration, environmental study, and crustal study. * Presents theoretical and methodological findings, as well as examples of applications of recently developed algorithms and software in solving practical problems * Describes the practical importance of electromagnetic data through enabling discussions on a construction of a closed technological cycle, processing, analysis and three-dimensional interpretation * Updates current findings in the field, especially with MT, magnetovariational and seismo-electrical methods and the practice of 3D interpretations

Developments In Geophysical Exploration Methods
Author: A. A. Fitch
Publisher: Springer Science & Business Media
Release Date: 2012-12-06
Pages: 234
ISBN:
Available Language: English, Spanish, And French
EBOOK SYNOPSIS:

One facet of development in this field is that the methods of gathering and processing geophysical data, and displaying results, lead to presentations which are more and more comprehensible geologically. Expressed in another way, the work of the interpreter becomes progressively less onerous. The contributions in this collection of original papers illustrate this direction of development, especially in seismic prospecting. If one could carry out to perfection the steps of spiking deconvolution, migration and time--depth conversion, then the seismic section would be as significant geologically as a cliff-face, and as easy to understand. Perhaps this is not yet achieved, but it remains an objective, brought closer by work such as that described by the authors. The editor offers his best thanks to the contributors-busy geophysicists who have written with erudition on this range of subjects of current interest. A. A.

Publisher: John Wiley & Sons
Release Date: 2011-03-03
Pages: 680
ISBN:
Available Language: English, Spanish, And French
EBOOK SYNOPSIS:

Humanity’s ever-increasing hunger for mineral raw materials, caused by a growing global population and ever increasing standards of living, has resulted in economic geology becoming a subject of urgent importance. This book provides a broad panorama of mineral deposits, covering their origin and geological characteristics, the principles of the search for ores and minerals, and the investigation of newly found deposits. Practical and environmental issues that arise during the life cycle of a mine and after its closure are addressed, with an emphasis on sustainable and "green" mining. The central scientific theme of the book is to place the extraordinary variability of mineral deposits in the frame of fundamental geological processes. The book is written for earth science students and practicing geologists worldwide. Professionals in administration, resource development, mining, mine reclamation, metallurgy, and mineral economics will also find the text valuable. Economic Geology is a fully revised translation of the the fifth edition of the German language text Mineralische und Energie-Rohstoffe.

Probability And Statistics In Geodesy And Geophysics
Author: Ludmila Kubackova
Publisher: Elsevier Science Limited
Release Date: 1987
Pages: 427
ISBN:
Available Language: English, Spanish, And French
EBOOK SYNOPSIS:

The purpose of data processing is to obtain in explicit form maximum information on the object of the data measurements. This is accomplished by the use of suitable models based on the most up-to-date knowledge of the theory of probability and mathematical statistics. The need to constantly improve models for processing data sets is stimulated by the rapid development of geodetic and geophysical measurement techniques on the one hand and the possibilities of contemporary computer techniques on the other. The reasons for the incessant improvement of mathematical models are both gnostic and economic; experiments in particular are time-consuming and expensive to prepare and carry out; moreover, they may be unique and impossible to repeat. To develop an effective method for preparing such experiments and a correct procedure for processing the results is a theoretically exacting, although least costly, part of the whole process of preparation, realization and the evaluation of the measurements. The purpose of this book is to acquaint the reader with the mathematical methods in use at present, including those being developed and applied in advanced geodetic and geophysical centres.

Computational Neural Networks For Geophysical Data Processing
Author: M.M. Poulton
Publisher: Elsevier
Release Date: 2001-06-13
Pages: 352
ISBN:
Available Language: English, Spanish, And French
EBOOK SYNOPSIS:

This book was primarily written for an audience that has heard about neural networks or has had some experience with the algorithms, but would like to gain a deeper understanding of the fundamental material. For those that already have a solid grasp of how to create a neural network application, this work can provide a wide range of examples of nuances in network design, data set design, testing strategy, and error analysis. Computational, rather than artificial, modifiers are used for neural networks in this book to make a distinction between networks that are implemented in hardware and those that are implemented in software. The term artificial neural network covers any implementation that is inorganic and is the most general term. Computational neural networks are only implemented in software but represent the vast majority of applications. While this book cannot provide a blue print for every conceivable geophysics application, it does outline a basic approach that has been used successfully.
