The Alaska Resource Data File (ARDF) is a subset of the National Mineral Resource Data System (MRDS) that has been specifically re-formatted and re-designed to better meet the needs of the local user community.
U.S. Geological Survey, Unknown, National Mineral Resource Data System (MRDS).
The location of a site is given in decimal degrees. Some sites are areas rather than points and the geographic coordinates are the approximate center of the area. The precision of the latitude and longitude is reflected in the number of decimal places given. A narrative description of the location and the precision of the location is given in the text field 'Location description and accuracy'.
ARDF is mainly concerned with the metallic commodities. Common industrial minerals such as sand and gravel, crushed stone, and limestone are not included, nor are energy minerals such as peat, coal, and oil and gas. Uranium and thorium, and rare earth elements are included, as well as high unit-value industrial minerals as barite, jade, graphite, and gypsum.
A site is a single geographic location, point or area, which may have had multiple site names. For historical perspective, all proper names are listed.
Are there legal restrictions on access or use of the data?
