Description: This map layer includes agricultural minerals operations in the United States. The data represent commodities covered by the Minerals Information Team (MIT) of the U.S. Geological Survey. The mineral operations are plants and (or) mines surveyed by the MIT and considered currently active in 2003. This is a replacement for the June 2004 map layer.
Description: This map layer includes construction minerals operations in the United States. The data represent commodities covered by the Minerals Information Team (MIT) of the U.S. Geological Survey. The mineral operations are plants and (or) mines surveyed by the MIT and considered currently active in 2003. Excluded are construction sand and gravel and crushed stone. This is a replacement for the June 2004 map layer.

Description: This datat set includes ferrous metal mines in the United States. The data represent commodities covered by the Minerals Information Team (MIT) of the U.S. Geological Survey, and the operations are those considered active in 2003 and surveyed by the MIT. This is a replacement for the November 1998 map layer.
Description: This data set includes ferrous metal processing plants in the United States. The data represent commodities covered by the Minerals Information Team (MIT) of the U.S. Geological Survey, and the operations are those considered active in 2003 and surveyed by the MIT. This is a replacement for the November 1998 map layer.
Description: The mine and the manufacturing plant need not be located in close proximity to each other to be "closely associated". Also, it is possible for more than one mine to be associated with a particular manufacturing plant, and for more than one manufacturing plant to be associated with a particular mine. A mine associated with a manufacturing plant represents an potential additional point of vulnerability to the manufacturing plant, likewise, the manufacturing plant represents a potential additional point of vulnerability to the mine. Any relevant transportation links between the two represents a third potential vulnerability. The links between the mines and the manufacturing plants are contained in the Mines_linked_to_ManufacturingID_table.dbf table. The [MINEID] field corresponds to the [SRCLNKID] attribute in this dataset. The [MNFID] corresponds to the [SRCLNKID] in the manufacturing dataset. Mines are typically large facilities. To enable a first responder or law enforcement team to easily drive to the mine the point representing the mine has been placed at the place where the main "haul road" meets the nearest public road. This location may be a considerable distance from the mine pit or shaft, but from this point on the ground it should be obvious how to drive to the mine itself. Text fields in this dataset have been set to all upper case to facilitate consistent database engine search results. All diacritics (e.g. the German umlaut or the Spanish tilde) have been replaced with their closest equivalent English character to facilitate use with database systems that may not support diacritics. The currentness of this dataset is indicated by the [CONTDATE] attribute. Based upon this attribute the oldest record dates from 06/06/2006 and the newest record dates from 10/12/2006.
Description: This data set includes miscellaneous industrial minerals operations in the United States. The data represent commodities covered by the Minerals Information Team (MIT) of the U.S. Geological Survey. The mineral operations are plants and (or) mines surveyed by the MIT and considered currently active in 2003. This is a replacement for the July 2004 map layer.
Description: This data set includes nonferrous metal mines in the United States. The data represent commodities covered by the Minerals Information Team (MIT) of the U.S. Geological Survey, and the operations are those considered active in 2003 and surveyed by the MIT. This is a replacement for the October 2003 map layer.
Description: This map layer includes nonferrous metal processing plants in the United States. The data represent commodities covered by the Minerals Information Team (MIT) of the U.S. Geological Survey, and the operations are those considered active in 2003 and surveyed by the MIT. This is a replacement for the October 2003 map layer.
Description: This map layer includes refractory, abrasive, and other industrial minerals operations in the United States. The data represent commodities covered by the Minerals Information Team (MIT) of the U.S. Geological Survey, and the operations are those considered active in 2003 and surveyed by the MIT. This is a revised version of the June 2004 map layer.
Description: This map layer includes sand and gravel operations in the United States. These data were obtained from information reported voluntarily to the USGS by the aggregate producing companies. The data represent commodities covered by the Minerals Information Team (MIT) of the U.S. Geological Survey, and the operations are those considered active in 2002 with production greater than 50,000 tons, which are non-government, non-portable, and surveyed by the MIT. This is a replacement for the January 2001 map layer.

Description: Mineral resource occurrence data covering the world, most thoroughly within the U.S. This database contains the records previously provided in the Mineral Resource Data System (MRDS) of USGS and the Mineral Availability System/Mineral Industry Locator System (MAS/MILS) originated in the U.S. Bureau of Mines, which is now part of USGS. The MRDS is a large and complex relational database developed over several decades by hundreds of researchers and reporters. This product is a digest in which the fields chosen are those most likely to contain valid information.

Description: This data set shows the coal fields of Alaska and the conterminous United States. Most of the material for the conterminous United States was collected from James Trumbull's "Coal Fields of the United States, Conterminous United States" map (sheet 1, 1960). The Gulf Coast region was updated using generalized, coal-bearing geology obtained from State geologic maps. The Alaska coal fields were collected from Farrell Barnes's "Coal Fields of the United States, Alaska" map (sheet 2, 1961).
