Book Description
Historic stratigraphic illustrations depict the earth beneath our feet in captivating hand-drawn diagrams. Each drawing tells a unique geologic story, exquisitely rendered in colors from pastel palettes to brilliant bolds that show evolving scientific graphic conventions over time. Created by federal and state geologists over the course of one hundred years, the maps reveal sedimentary rock layers that present an unexpected view of our treasured public lands, making this collection an important record of natural resources, as well as a beautiful display of map design. The fascinating history of the science behind the drawings is explored by sedimentary geologist Jody Bourgeois, a professor emeritus at the University of Washington's College of the Environment and a fellow of the Geological Society of America.

Book Description
Designed to be carried in the field, this pocket-sized how-to book is a practical guide to basic techniques in mapping geological structures. In addition to including the latest computerised developments, the author provides succinct information on drawing cross-sections and preparing and presenting 'fair copy' maps and geological diagrams. Contains a brief chapter on the essentials of report writing and discusses how to keep adequate field notebooks. A checklist of equipment needed in the field can be found in the appendices. Quote from 3rd edition "provides a wealth of good advice on how to measure, record and write reports of geological field observations" The Naturalist

Book Description
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.
