A direct means of indicating the presence of concealed mineralization would be the ultimate in exploration. In many ways the.induced-polarization (IP) technique comes close to achieving this goal. it has been remarkably successful in locating concealed bodies containing even small percentages of metallic-luster minerals.

When I put pen to paper in the summer of 1982, uppermost in my mind was the need to provide new practitioners with an introduction to the theory and practice of thermoluminescence (TL) dating, particularly those without a strong background in physics. Assimilating the corpus of specialist papers which at present define the theory and practi…
This practical step by step guide describes the key geological field techniques needed by today's exploration geologists involved in the search for metallic mineral deposits. The techniques described are fundamentals to the collection, storage and presentation of geological data and their use to locate ore. This book explains the various tasks which…
There are few places in the developed world particularly where the coal industry does not feel that it faces major challenges. Climate change, safety and a variety of other environmental.issues are just some of the concerns. In many cases these concerns are justified, and certainly in the developing world much more needs to be d…
Each year approximately 40 million metric tons of processed kaolin are sold around the world into markets ranging from brick making to paper coating. This functional versatility is a direct consequence of natural variability in deposit quality, which is controlled by mineralogy and processing. Poorer quality deposits, which contain relatively large …
A century has passed since the first X-ray diffraction experiment (Friedrich et al.1912). During this time, X-ray diffraction has become a commonly .used technique for the identification and characterization of materials and the field has seen continuous development. Advances in the theory ofdiffraction, in the generation o…
Archaeological geophysics is not the kind of research one can do alone. Every project I have worked on, whether field research, data processing, or software development, has involved someone in a crucial capacity towhom.I owe a great deal. My great thanks go to Ieffrey Lucius at the U.S. Geological Survey in Denver, Colorado, who first held my…
There is a new breed of superhero in, the world, and you are one of them. These new superheroes are part of a special club. Not the Justice League, nor theAvengers, They are GPR practitioners. Congratulations on beirig part of this exclusive club! I am not calling you a superhero for the reason you probably think.Yes, you h…
In the field of applied geophysics, the geoelectric methods have been important for about a century, particularly for shallow and near-surface investigations. Geoelectric methods are used extensively to locate buried targets that are conductive and resis• tive in nature. The purpose of active geoelectric surveys is to determine the subsur• face …
Ground Penetrating (or Probing) Radar, more commonly known as GPR, is sirriply one of the most useful geophysical techniques available to engineers and scientists;' It allows us to detect what lies beneath the ground or within buildings. It is primarily a safety aide since it' is used to prevent potentially dangerous situations arising or for the de…
