Download or read book Critical Mineral Resources of the United States written by K. J. Schulz and published by Geological Survey. This book was released on 2017 with total page 868 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Book excerpt: The Gospel-Hump Wilderness lies in central Idaho. A mineral survey of the 206,500 acre area in Idaho County was conducted by the U.S. Geological Survey and the U.S. Bureau of Mines during 1980 to 1983. The study consisted of new geologic mapping, geochemical sampling of the wilderness and vicinity, geophysical surveying, and investigation of claim blocks in or near the wilderness. Fractures in the roof zone of plutons of the Idaho batholith host gold and silver deposits in mining districts that are contiguous with and included in the Gospel- Hump Wilderness. Subeconomic gold and silver resources are indicated and inferred at the War Eagle and Blue Jay mines (southeastern part of the area). Parts of the eastern half of the wilderness area, which are included in mining districts and which are along the trends of known mineralized fractures, have a high potential for gold and silver resources and moderate potential for copper, lead, zinc, and molybdenum resources in quartz fissure-veins. Other parts of the wilderness that have the same geologic setting have a moderate potential for gold and silver resources in undiscovered quartz veins that lie along the trend of or are parallel to known veins. The western third of the wilderness has a moderate potential for tungsten, silver, lead, copper, nickel, and possibly gold resources in skarn or metasomatic replacement deposits along thrust faults adjacent to carbonate units.

Download or read book The Changing Role of Geological Surveys written by P.R. Hill and published by Geological Society of London. This book was released on 2020-12-07 with total page 300 pages. Available in PDF, EPUB and Kindle. Book excerpt: Senior managers and Heads of Geological Survey Organizations (GSOs) from around the world have contributed a collection of papers to provide a benchmark on how GSOs are responding to national and international needs in a rapidly changing world. GSOs continue to provide key scientific information about Earth systems, natural hazards and climate change. As countries adopt sustainable development principles and the public increasingly turns to social media to find information about resource and environmental issues, the generation and communication of Earth science knowledge become increasingly important. This volume provides a snapshot of how GSOs are adapting their activities to this changing world. The different national perspectives presented converge around several common themes related to resources, environment and big data. Climate change and the UN’s Sustainable Development Goals provide an increased incentive for GSOs of the world to work in harmony, to generate knowledge of Earth systems and to provide solutions for sustainable management of the planet.

Download or read book The History of Mining and Geological Surveys in Jamaica written by Suresh Bhalai and published by Springer Nature. This book was released on 2023-10-24 with total page 170 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mining and geological survey work in Jamaica goes back several hundred years and was initiated by the Europeans when they colonized the Island. The year 2019 marked 160 years since the first Government-commissioned Geological Survey of Jamaica. This is one of the oldest survey activity of this type in the World! This book seeks to commemorate this heritage. It is one of the first books of its kind examining the evolution of the mineral sector and geological survey work of Jamaica, set in the framework of the Country's history of over 500 years. The Reader will explore a relatively unfamiliar side of the Country's development, linked to popular historical stories that shaped the Nation. The information presented are mostly documented in dated academic literature that are not gauged for a wide audience. This book however, aims to make this information accessible for a wider readership such as students, amateur scientist, non-professionals or anyone who wishes to learn about the rich history and heritage, and the contributions to national development from Europe and much later, North America.
