Nickel Sulfide Ores and Impact Melts: Origin of the Sudbury Igneous Complex presents a current state of understanding on the geology and ore deposits of the Sudbury Igneous Complex in Ontario, Canada. As the first complete reference on the subject, this book explores the linkage between the processes of meteorite impact, melt sheet formation, differentiation, sulfide immiscibility and metal collection, and the localization of ores by magmatic and post-magmatic processes. The discovery of new ore deposits requires industry and government scientists and academic scholars to have access to the latest understanding of ore formation process models that link to the mineralization of their host rocks. The ore deposits at Sudbury are one of the world's largest ore systems, representing a classic case study that brings together very diverse datasets and ways of thinking. This book is designed to emphasize concepts that can be applied across a broad range of ore deposit types beyond Sudbury and nickel deposit geology. It is an essential resource for exploration geologists, university researchers, and government scientists, and can be used in rock and mineral analysis, remote sensing, and geophysical applications. - Provides the only reference book to focus entirely on the Sudbury Igneous Complex - Brings together an understanding of ore deposit and impact melts as a basis for future exploration - Authored by a leading expert on the geology of the Sudbury Igneous Complex with 35 years of experience working on nickel sulfide ore deposits

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.

This timely and topical look at the role of ethics in fieldwork takes into account some of the major issues confronting qualitative researchers. The main purposes of this book are twofold: to promote an understanding of the harmful possibilities of fieldwork; and to provide ways of dealing with ethical problems and dilemmas. To these ends, examples of actual fieldwork are provided that address ethical problems and dilemmas, and posit ways of dealing with them.
