DOWNLOAD EBOOKFrom the Eastern Shore to Cumberland Gap, Virginia stretches across five distinct regions, each home to unique and amazing geology. In the Coastal Plain's wedge of fossil-rich sediments, a meteor impact crater"¬‚¬"the sixth largest on Earth"¬‚¬"helped determine the location of Chesapeake Bay. The Piedmont begins at the Fall Line, the series of East Coast waterfalls that mark the upstream limit to ship navigation, such as Belle Else in Richland, where the turbulent James River erodes potholes in the Petersburg Granite. Rising up from the rolling hills of the Piedmont, the Blue Ridge forms the spine of the state, its hard basalt and gneisses on display at Shenandoah National Park. Farther west, limestones in the Valley and Ridge are riddled with caves and sinkholes, with dissolution forming one of the wonders of the world at Natural Bridge State Park. Along the very western edge of the state is the Appalachian Plateau, where the No. 3 coal, know as America's Favorite Fuel was extracted from the historic Pocahontas Mine. Virginia Rocks! is part of the state-by-state Geology Rocks! series that introduces readers to some of the most compelling and accessible geologic sites in each state. Author Albert Dickas has picked 50 of the best sites in Virginia for discussing the enormous variety of rocks, minerals, and landforms created over the course of the states more than 1 billion years of geologic history.

DOWNLOAD EBOOKAs 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.
