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.

Where on Earth is it like Mars? How were the Apollo astronauts trained to be geologists on the Moon? Are volcanoes on Earth just like the ones on other planets? The exploration of our solar system begins in our own backyard. Discoveries on other planetary bodies cannot always be easily explained. Therefore, geologic sites on this planet are used to better understand the extraterrestrial worlds we explore with humans, robots, and satellites. Analogs for Planetary Exploration is a compilation of historical accounts of astronaut geology training, overviews of planetary geology research on Mars, educational field trips to analog sites, plus concepts for future human missions to the Moon. This Special Paper provides a great overview of the science, training, and planning related to planetary exploration for students, educators, researchers, and geology enthusiasts. After all, as we learn about the solar system we can better understand our own planet Earth.

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.
