Book excerpt: This report describes a system designed to measure the concentrations of potassium, uranium, and thorium in boreholes. The system is divided into a linear pulse processing subsystem that consists of the probe and part of the surface electronics, and a digital recording subsystem. Gamma rays are detected in one of two NaI (Tl) crystals and the voltage pulses resulting from the scintillations in the crystal are linearly transmitted to the surface. The pulses are separated and counted in each of three channels corresponding to a window of energies in the gamma-ray spectrum. The resulting counts are then recorded on magnetic tape and optionally listed on a printer and strip-chart recorder. The recorded data are processed at a central computer where a graphic display of potassium, uranium, and thorium concentrations is constructed. Following a detailed description of the spectrometer system, some geologic/lithologic relationships are suggested where this system can be applied; some examples of log data obtained with this system are also included. 22 figures, 6 tables.

This book was released on 2012-12-06 with total page 352 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is a collection of original papers, each by an expert in his field. They deal with different sectors of recent geophysical development. It may be, at first, difficult to see what else unites them, and how these several technologies can contribute to an integrated exploration process. What brings these writers together is that they have all contributed to the improvement of what comes to the eye of the geophysical interpreter. Some of the improvement is achieved at the data-gathering stage, some of it in processing, and in presentation. For all of this improvement interpreters in general are most grateful. The editor is appreciative in a quite personal way, not only of the advances in technology, but also of the effort in writing which has been made by these busy contributors, and so created this collection. Something can be said here about interpretation and the environment in which it is carried out, since it represents the field where the results of these technical developments are ultimately tested. In the commercial world it is from the geophysical interpreter that management learns the results of a large sector of exploration expenditure, and learns them in a form on which still larger expenditures on later phases of exploration can be based.

Available in PDF, EPUB and Kindle. Book excerpt: Gamma-Ray Spectrometry of Rocks: Methods in Geochemistry and Geophysics provides information pertinent to the fundamental aspects of the gamma-ray spectrometry of rocks. This book discusses the increasing interest in using gamma spectrometry in the search for uranium ore. Organized into seven chapters, this book begins with an overview of the approximate frequency and wave length of electromagnetic radiations. This text then examines the quantitative detection of X and gamma photons, which is based upon their interactions with matter. Other chapters consider the inorganic scintillation crystals as the most favorable detectors due to its requirement of a high intrinsic efficiency. This book discusses as well the shape of the spectrum of a monoenergetic gamma-ray beam, which is dependent on the photon energy. The final chapter deals with the determination of the abundances of natural radioisotopes and their stable end products in a rock or mineral. This book is a valuable resource for radiological health physicists, chemists, geochemists, and exploration geologists.

Available in PDF, EPUB and Kindle. Book excerpt: Developments in Economic Geology, 7: Nuclear Methods in Mineral Exploration and Production elaborates on the status of applicable nuclear techniques used in mineral exploration and production. The selection first offers information on radiometric methods and X-ray analysis in mineral exploration. Discussions focus on gamma-ray spectrometry, radon detection, autoradiography of uranium and thorium, X-ray diffraction, and application of X-ray analysis. The text then examines X-ray fluorescence geochemical analysis on the surface of Mars and radioactivation methods, as well as nuclear geochemical measurements of planetary surface; radioactivation methods for mineral exploration; and radioactivation sources. The publication takes a look at nuclear well logging for petroleum and the potential of plowshare for resource development. Topics include natural radiation, induced logs, description of potential applications related to energy resources, and obstacles to the development of a commercial plowshare program in the U.S. The selection is a dependable source of data for readers interested in the use of nuclear techniques in mineral production and exploration.

Available in PDF, EPUB and Kindle. Book excerpt: Gamma-ray transport calculations were performed to determine the energy distribution of gamma rays inside a borehole introduced into an infinite medium. The gamma rays from the naturally occurring radioactive isotopes of potassium, thorium, and uranium were uniformly distributed in a sandstone formation (having a porosity of 0.30 and a saturation of 1.0) surrounding the borehole. A sonde was placed coaxially inside the borehole. Parametric studies were done to determine how the borehole radius, borehole fluid, and borehole casing influence the gamma-ray flux inside the sonde.

This book was released on 1993 with total page 24 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Geological Survey of Canada has been involved with the calibration of borehole gamma-ray spectrometers since 1977 when it constructed the first borehole gamma-ray calibration facilities. Inconsistencies in the results from intercomparisons with other facilities demonstrated the importance of reliable quantitative gamma-ray borehole measurements. The model boreholes described in this bulletin have been designed to avoid many of the problems associated with the construction of borehole calibration facilities which were revealed through the intercomparison exercises. This report should therefore be of practical use to those wishing to construct similar calibration facilities elsewhere.

This book was released on 2012-12-06 with total page 317 pages. Available in PDF, EPUB and Kindle. Book excerpt: One of the themes in current geophysical development is the bringing together of the results of observations made on the surface and those made in the subsurface. Several benefits result from this association. The detailed geological knowledge obtained in the subsurface can be extrapolated for short distances with more confidence when the geologi cal detail has been related to well-integrated subsurface and surface geophysical data. This is of value when assessing the characteristics of a partially developed petroleum reservoir. Interpretation of geophysical data is generally improved by the experience of seeing the surface and subsurface geophysical expression of a known geological configuration. On the theoretical side, the understanding of the geophysical processes themselves is furthered by the study of the phenomena in depth. As an example, the study of the progress of seismic wave trains downwards and upwards within the earth has proved most instructive. This set of original papers deals with some of the more vigorous developments in subsurface geophysics: and it is hoped that it will contribute to the understanding of geophysical phenomena in the solid. The editor thanks the busy workers in the several fields who have made time to produce these contributions.
