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.

Book Description
Excerpt from Contributions to the Geology of Mineral Deposits: A. Exploration for Porphyry Metal Deposits Based on Rutile Distribution, a Test in Sumatera; B. Titanium Mineral Resources of the United States, Definitions and Documentation At the Tangse porphyry-copper prospect, rutile in thick soil reflects the distribution of the quartz-sericite and biotite-chlorite zones of hydrothermal alteration at depth. Detection of rutile in the samples is not simple, but studies of rutile distribution may nevertheless be a cheap exploration method for tropical porphyries.

Book Description
Contributions to Mineralization provide some new aspects on economically important mineral deposits from various locations in Asia, Africa, and Europe in terms of their genesis, geochemical, and age considerations. Mining industry and mineral engineering issues are also discussed in the book through some new statistical approaches and economic aspects. The book represents a useful guide for specialists in the fields of mineralogy, economic geology, mining engineering, environmental impacts, and mining industry.
