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.

Regional tracts of land where the geology is permissive for the occurrence of undiscovered porphyry copper deposits, with probabilistic estimates of undiscovered resources, along with tables of discovered deposits and prospects.

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 sediment samples from the National Geochemical Database. Primarily inorganic elemental concentrations, most samples are of stream sediment in the continental US and Alaska.

Geochemistry of concentrates 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.
