Investigates the expanding LED industry and it’s manufacturing complexities. The sources and supply of the select mineral commodities used and the manufacturing process and supply chain are discussed.

Delineated permissive areas for undiscovered porphyry copper deposits, compiled a database of known deposits and significant prospects, estimated undiscovered deposits within those areas and made probabilistic estimates of their metal content.

Sources are discussed to identify risks to the United States associated with critical supply of this strategic mineral / metal and to provide supply chain transparency to policymakers. Focus is on the post-mining, pre-consumer-product part of the chain.

Investigates the complexity of mineral and metal supply chains in general and shows how they can be mapped. A supply chain is made up of all the manufacturers, suppliers, and information networks supplying materials and parts for production.

This map displays over 1,500 records of mineral facilities throughout the continent of Asia and the countries of the Pacific Ocean. Each record represents one commodity and one facility type at a single geographic location. Facility types include mines, o

Location, type, mineralogy, name, tonnage and grade, and geological setting for 120 deposits of this type. The US has no active nickel mines or nickel reserves.

Geological characteristics and resource estimates for 36 known deposits of this type worldwide.

Geochemical analysis of rock samples collected and analyzed by the USGS. This dataset includes and supersedes rock data formerly released as "Geochemistry of igneous rocks in the US extracted from the PLUTO database"

MRDS describes metallic and nonmetallic mineral resources throughout the world. Included are deposit name, location, commodity, deposit description, geologic characteristics, production, reserves, resources, and references.

Geochemical analysis of soil samples from the National Geochemical Database. Primarily inorganic elemental concentrations, most samples are from the continental US and Alaska.

Deposits, prospects, and permissive tracts for porphyry and sediment-hosted copper resources worldwide, with estimates of undiscovered copper resources.

Information on titanium-vanadium deposits hosted in mafic-ultramafic layered intrusions and massif anorthosite intrusions from around the world. Includes only deposits with reported grade and tonnage information. Data are provided in CSV and shapefile formats.

Geochemical data for stratigraphic rock sequences containing dominantly fine-grained clastic rocks with appreciable organic carbon (above 0.5 weight percent), usually known as 'black shale facies examples' but including all fine-grained clastic rocks such as argillite, mudstone, claystone, and their low-medium grade metamorphic equivalents. Data are provide in Microsoft Access and tab-delimited text formats.

Chemistry and geologic information for historic ore and ore-related rock samples from mineral deposits in the United States and from archetypal deposits from 27 other countries. Data are provide in Microsoft Access, Microsoft Excel, and CSV formats.

Statistics for over 88 nonfuel mineral commodities including items such as production, imports, exports, price, stocks, apparent consumption, and/or net import reliance for nonfuel mineral commodities. Data are provided in CSV format.

Uranium and lead isotope ratios from (1) scheelite from ore deposits near Mallnock, Austria, (2) wolframite from the Wolfram Camp mine, Australia, and (3) scheelite from the Andrew Curtis mine near Los Angeles, California. Data are provided in CSV format.
