Ore Geology and Industrial Minerals: An IntroductionMuch new data and many new ideas have emerged in the area of ore geology and industrial minerals since publication of the second edition of this text in 1987. The overriding philosophy behind this new edition is the inclusion and integration of this new material within the established framework of the text. The third edition is re-presented in the modern double-column format. Non-metallic deposits of industrial and bulk materials are fully covered to meet the changing emphasis of courses in applied geology. In addition, chapter 1 has been considerably enlarged to include a section on mineral economics covering metals, industrial minerals and bulk materials. In this section, the various aspects of economic exploitation of industrial and bulk materials are compared with those of metallic deposits. Other major revisions and additions include a section on fluid inclusions, expansion of the section on wall rock alteration, expansion of the material on isotope studies, and the inclusion of a section on hydraulic fracturing and seismic pumping. |
