Tungsten Deposits in the United States

Tungsten deposits have been mined in the United States since the late 19th century, but there has been minimal production of tungsten from mines in the United States since price crashes in the 1980’s. Tungsten is necessary for strategic, consumer, and commercial applications. Due to its strength, hardness, high melting and boiling points, tungsten is used in wear-resistant...

Cobalt Deposits in the United States

This data release provides descriptions of more than 60 mineral regions, mines, and mineral deposits within the United States and its territories that are reported to contain enrichments of cobalt (Co). To focus the scope of this data release, we report only mined deposits and exploration prospects with past production, or resource and reserve estimates of 1,000 metric tons or more of cobalt...

Detection Limits

(Intro) (mg = µg) Elemental detection limits for NAA are variable because some elements become very radioactive–, and can be determined at very low levels while other elements do not become very radioactive or have very short half–lives (less than 10 seconds). Activation analysis determines the total mass of an element in a sample.

Rhenium Occurrences in the United States

This data release provides descriptions of more than 100 mining districts, mines, and mineral occurrences (deposits and prospects) within the United States that are reported to contain enrichments of rhenium (Re). These mineral occurrences include mined deposits, exploration prospects, and other occurrences with notable concentrations of rhenium. The inclusion of a particular mineral...

Database of significant deposits of gold, silver, copper, lead, and zinc in Alaska

This data release provides descriptions and locations of 134 significant deposits in Alaska. Approximately 99 percent of past production and remaining identified resources of gold, silver, copper, lead, and zinc in the United States are accounted for by deposits that originally contained at least 2 metric tons (t) of gold, 85 t silver, 50,000 t copper, 30,000 t lead, and 50,000 t zinc....

Global rare earth element occurrence database

This spatial database "usgs_Global_REE.gdb" was created for use in a geographic information system (GIS) to support research on global rare earth deposits and occurrences by the U.S. Geological Survey. This inventory documents the geologic occurrence of rare earths, including mineralogy, type of deposit or occurrence, host rocks and alteration, and any quantitative data related to size and...

Geochemistry of ore, host rock, and mine waste pile samples of iron oxide-apatite (IOA) deposits of the eastern Adirondack Highlands, New York, in relation to potential rare earth elements resources

The ore from historic iron mines of the eastern Adirondack Highlands, New York, contain abundant quantities of rare earth element (REE)-bearing apatite crystals. These apatite crystals are especially enriched in Y, La, Ce, and Nd. In-ground ore, mine waste piles, and tailings piles that are associated with these mines could contain apatite and other REE-bearing phases at elevated...

Shapefile to accompany Colorado Mineral Belt revisited

Although much discussed in the literature, maps showing the detailed outline of the Colorado Mineral Belt are lacking. Lovering and Goddard (1950) show the geology and mines associated with the "Front Range mineral belt" but do not indicate an outline on plates or figures. Tweto and Sims (1963) published the outline of the Colorado mineral belt as page-size illustrations, differing on each....
