The Deposit Modeling Program was founded by UNESCO-IUGS with the major aim to disseminate knowledge from scientists in more developed countries to their counterparts from less developed ones. A fringe benefit of this effort was the compilation of information on existing models and promotion of topical workshops in developing countries. This book is the result of one such workshop that took place in Delhi and Udaipur, India, in December 2001. Sediment-hosted Lead-Zinc Sulphide Deposits compiles the work of renowned economic geologists from three continents. The authors highlight the recent advances in the understanding of the temporal and tectono-stratigraphic distribution of sediment-hosted Pb-Zn sulphide ores and processes governing their genesis. The first section comprises five chapters covering some of the most important deposits of this class in Australia and Canada in detail, emphasizing their genetic models. It also includes a paper on the "geoenvironmental model," which concerns behavior before mining and resulting from mining, processing, and smelting. The second section discusses the mineralized terranes in the state of Rajasthan, northwest India, which host three major sulphide deposits. This reference is packed with color and black and white photographs, illustrations, charts, and graphs, making it a valuable, up-to-date resource for any geologist or geotechnical scientist studying major mineral deposits.

The present volume Stratabound Ore Deposits in the Andes has its roots in an international seminar on stratabound ore deposits which took place in September 1986 in Cusco, Peru, sponsored by Multi ciencias (Peru) and UNESCO. During this seminar it became clear that the amount and quality of research done on stratabound ore deposits in the Andes required a synthesis. Researchers in industry and government as well as in academia, including many which had participated at the Cusco Seminar, were invited to contribute. The answer was extremely positive, confirming the idea that a book expressing the state of the art of the study of stratabound ore deposits in the Andes was long overdue. As editors we sought to give maximum coverage to the present knowledge, yet keeping the length, and thereby the price, within rea sonable limits. The book contains three types of contributions. In the first part the reader will find review papers focusing on ( 1) the geologic framework (Frutos), (2) the metallogenesis in Andean countries including also types of deposits differing from those of stratabound nature (Cardozo and Cedillo, Oyarzun), and (3) an in troductory overview of the stratabound ore deposits in the Andes, emphasizing their geotectonic position as a classification tool (Font bote).

As the importance and dependence of specific mineral commodities increase, so does concern about their supply. The United States is currently 100 percent reliant on foreign sources for 20 mineral commodities and imports the majority of its supply of more than 50 mineral commodities. Mineral commodities that have important uses and face potential supply disruption are critical to American economic and national security. However, a mineral commodity's importance and the nature of its supply chain can change with time; a mineral commodity that may not have been considered critical 25 years ago may be critical today, and one considered critical today may not be so in the future. The U.S. Geological Survey has produced this volume to describe a select group of mineral commodities currently critical to our economy and security. For each mineral commodity covered, the authors provide a comprehensive look at (1) the commodity's use; (2) the geology and global distribution of the mineral deposit types that account for the present and possible future supply of the commodity; (3) the current status of production, reserves, and resources in the United States and globally; and (4) environmental considerations related to the commodity's production from different types of mineral deposits. The volume describes U.S. critical mineral resources in a global context, for no country can be self-sufficient for all its mineral commodity needs, and the United States will always rely on global mineral commodity supply chains. This volume provides the scientific understanding of critical mineral resources required for informed decisionmaking by those responsible for ensuring that the United States has a secure and sustainable supply of mineral commodities.

This Special Publication combines results obtained by interdisciplinary groups from numerous academic institutions working on Paleoproterozoic formations to decipher the origins of the main mineralization resources in the West African Craton (WAC) and their impacts on African economic development. Structural, geophysical, sedimentological, stratigraphical, geochemical, petrophysical and mineralogical analyses have been used to highlight the complexities involved in mineralization emplacement and its origin and evolution within the WAC. Fourteen articles contribute to new knowledge in mineral research. They show that the geodynamic evolution of the WAC is complex from one area to another: it involves subduction, collision and obduction during several deformation phases ranging from Birimian (2.3–2.0 Ga) to Pan-African (650–450 Ma) events. Various modelling techniques, when integrated, help in understanding the mechanisms of mineralization emplacement, some of which are still a matter of debate. The challenge for further studies is mitigation for sustainable development that can be appropriately used to minimize such damage.
