This is the completely revised edition of a book which was published in 1978 and, such was its popularity, was sold out within two years. It was described as ``An excellent compilation and condensation of a vast field of literature and experience in economic geology. Clear illustrations, charts and tables punctuate the text material very nicely... Valuable for all economic geologists and resource developers.'' (Choice).The material is illustrated by 215 text figures and 76 tables, and is presented in two parts. The first part covers the geological background of the genesis of mineral deposits as a clue to new discoveries, and the methods of geological, geochemical and geophysical prospecting. The second part concerns sampling, documentation and computation of ore reserves and economic assessment of mineral deposits. This new edition has been very extensively revised and brought up to date. This holds true particularly for the chapters on geochemical and geophysical methods, the use of photo-geology and satellite imagery, oil and gas prospecting, exploration of underwater minerals, the application of the principles of global tectonics in prospecting for deposits, and the evaluation of reserves. These new or thoroughly revised chapters comprise almost half of the entire text.

Developments in Economic Geology, 15: Geochemical Exploration 1980 focuses on practices, processes, methodologies, and principles involved in geochemical exploration. The selection first takes a look at the simultaneous determination of sulfide, polysulfides, and thiosulfate as an aid to ore exploration; hydrogeochemical exploration for uranium ore deposits; and mercury and mercury compounds in surface air, soil gas, soils, and rocks. Discussions focus on the methods of mercury analysis, calibration, sensitivity and computations, exploration, titration of hydrogen sulfide, polysulfides, thiosulfate and sulfite, and leaching of a sulfide deposit by percolating water. The book then examines meteorological noise in crustal gas emission and relevance to geochemical exploration; a mercury vapor survey in an area of thick transported overburden in Shanghai, China; and mechanisms of ore formation and primary dispersion at the Dexing porphyry copper deposit in Jiangxi and their implications to geochemical exploration. The publication explores the organic matter of a gulf coast well studied by a thermal analysis; selective extraction procedures applied to geochemical prospecting in an area contaminated by old mine workings; and application of radionuclide energy-dispersive X-ray fluorescence analysis in geochemical prospecting. The selection is a vital source of data for researchers interested in geochemical exploration.

Empirical Metallogeny: Depositional Environments, Lithologic Associations, and Metallic Ores, Vol. 1: Phanerozoic Environments, Associations, and Deposits, Part B focuses on the composition, characteristics, properties, and reactions of Phanerozoic metallic ore deposits. The book first offers information on intracrustal and subcrustal environments and plutonic granite, diorite, (gabbro) association (GDG) and its aureole. Discussions focus on petrography, origin, and setting of GDG plutonic rocks; mineralization styles associated with Phanerozoic (higher-level) granite, diorite, (gabbro) association; copper skarns and carbonate replacements; and magnetite skarn and replacement deposits. Manganese, uranium, antimony, mercury, and arsenic deposits, hydrothermal iron ores, and hydrothermal-plutonic silver deposits are also discussed. The publication also takes a look at high- to medium-grade metamorphosed terrains, katazonal granites and pegmatites and continental fragmentation, rifts, and paleo-rifts. Topics include examples of modern rift and taphrogenic systems; mineralization styles in and related to the zone of ultrametamorphism and granitization; and petrography, origin, and setting of high-grade metamorphic terrains. The text is a valuable reference for readers interested in the study of Phanerozoic metallic ore deposits.

This is the most comprehensive, all-embracing, single source of data on metallic deposits and their worldwide distribution. With over 1,750 pages it contains: 594 figures illustrating ore styles and their setting; 113 tables providing concise but highly quantitative data on several thousand locality examples; 4 indexes (general, locality, genetic, metals) enabling rapid and thorough searches; and more than 2,000 references. This vast body of information on metallic ore deposits is arranged by environments in which they presently form or lithologic associations in which they occur. The organization of the book follows the approach employed in regional mineral-potential evaluation and exploration. Long-lasting, objectively observable host units and empirical indicators of ore presence are stressed. The coverage is balanced and truly worldwide, based on original literature consulted in over 30 languages and on the author's personal familiarity with more than 2,000 ore deposits located in 85 countries. The book is a must for practising exploration geologists, petrologists, and economic geologists, as well as for specialists in various other branches of geology (e.g. glacial geologists, carbonate sedimentologists, volcanologists, and geochemists). Teachers and students will find this most complete data sourcebook an ideal supplement to the theory and basic data found in textbooks.

Regional Studies and Specific Deposits deals with regional studies of strata-bound and stratiform ore deposits. Topics covered include the geological association between coal and metallic ores; the genesis of iron ores in banded iron-formation (BIF) by supergene and supergene-metamorphic processes; mineral zoning in sediment-hosted copper deposits; and the formation of gossans. The role of hydrothermal karst phenomena in the formation of Mississippi Valley-type deposits is also discussed. Comprised of five chapters, this volume begins with a review of the geological association of coal and metallic ores, focusing in particular on which metallic accumulations could be expected to be possibly present, within or close to the coal. The next chapter examines the origin of strata-bound enrichment deposits derived from BIF and presents the basic conceptual model for BIF-derived iron ores. The evolution of sulfide mineral zonation in low-temperature, sediment-hosted copper deposits is then evaluated. The book also describes the processes underlying the formation of gossans before concluding with an analysis of the hydrothermal karst phenomena as a factor in the development of Mississippi Valley-type deposits. This handbook will be useful to students, practitioners, and researchers in the fields of energy and earth sciences, mineralogy, mining, and metallurgy.
