Excerpt from The Enrichment of Ore Deposits The problems of superficial alteration and enrichment are not simple. Not only do the several metals segregate in different ways, but each metal may behave differently in different mineral associa tions. Every district and every deposit should be studied separately in the light of all available chemical and geologic data. There are, however, certain laws Of segregation that almost invariably are clearly indicated, and as data have accumulated many puzzling ap parent exceptions to these laws have disappeared. This paper is an amplification of, an earlier Survey bulletin on the enrichment of sulphide ores (bulletin It is a discussion of representative deposits, especially Of the paragenesis of their ores and of the principles that underlie the processes of enrichment. I hope it may suggest to those engaged in geologic work and in mining some lines Of approach to the solution of the complex problems that are encountered in the field. I realize fully that there may be serious omissions and possibly errors in the discussion of the complex problems here presented. I shall esteem it a favor if anyone whose statements I may have mis quoted or misinterpreted will set me right, and if those who have had superior opportunities for study Of certain districts will correct any wrong impressions that I may have given.

This book presents a new synthesis of the major metallogenic provinces of Europe and the geodynamic processes involved that can lead to the formation of world-class ore deposits. It represents the culmination of a 5-year research programme, GEODE, set up by the European Science Foundation, that brought together researchers across Europe from a wide range of disciplines into collaborative research projects. They focused on five metallogenic provinces across Europe; the Precambrian Fennoscandian Shield, the Upper Palaeozoic Urals, the Variscides of France and SW Iberia, the Alpine-Balkan-Carpathian-Dinaride belt and sediment-hosted deposits of Europe. Because of the long and well-known tectonic history of Europe and the diversity of ore deposits, linkages between geodynamics and ore deposit evolution have been established and new insights into mineralizing fluids and ore formation processes have been gained. Presented as a set of individual review papers and a final synthesis, this book offers a coherent and structured appraisal of geodynamics and metallogeny in Europe, with valuable lessons for mineral exploration and research throughout the world.

The fundamental concepts of fractal geometry and chaotic dynamics, along with the related concepts of multifractals, self-similar time series, wavelets, and self-organized criticality, are introduced in this book, for a broad range of readers interested in complex natural phenomena. Now in a greatly expanded, second edition, this book relates fractals and chaos to a variety of geological and geophysical applications. All concepts are introduced at the lowest possible level of mathematics consistent with their understanding, so that the reader requires only a background in basic physics and mathematics.

This thoroughly revised and expanded new edition incorporates the most recent research findings on the subject, such as the discovery of dramatic undersea hydrothermal vents. It describes the key process in the generation of ore deposits and emphasizes solid theoretical understanding.

This comprehensive reference examines all aspects of mineral processing, from the handling of raw materials to separation strategies to the remediation of waste products. It incorporates state-of-the-art developments in the fields of engineering, chemistry, computer science, and environmental science.
