Geologic datasets for weights of evidence analysis in northeastWashington--3. Minerals-related permits on national forests, 1967to 1998
Permits to explore for and (or) develop mineral resources onFederal lands can be used to indicate locations and types ofmineral-related activities on national forests. Permits for theseactivities require filing of a Notice of Intent to conduct mineralexploration activities and (or) a Plan of Operation, ifsignificant land disturbance results. This compilation of noticesand plans for the Colville, Kaniksu, Okanogan, and Wenatcheenational forests between 1967 and 1998 is intended for use incombination with geologic and economic information to predictfuture mineral-related activities in the region.
Preliminary digital map of cryptocrystalline occurrences in northern Nevada: rkhnd (ArcView shapefile) and rkhnd_crypto (ArcInfo point coverage)
A polygon Arcview shapefile of northern Nevadacryptocrystalline occurrences derived from Nevada rockhoundguides and converted to a coverage.
This dataset contains latitudes, longitudes, and otherdescriptive data for aggregate producers in New Mexico that arebelieved to have been active during the period 1997-1999. The datain this compilation were derived from U.S. Geological Survey files,U.S. Bureau of Land Management files, contact with producers, andreports from the New Mexico Bureau of Mines and Mineral Resources,the New Mexico Bureau of Mine Inspection, and the New Mexico Miningand Mineral Division. This dataset includes 2 tables: Table 1 containscrushed stone operations and table 2 contains sand and gravel operations.
Digital data for construction material sources reported bythe Arizona Department of Transportation in 1977 for MaricopaCounty, Arizona
The data set marpits1 is an ArcInfo coverage of point featuresrepresenting pit locations and attribution data captured froman atlas of map sheets and pit data sheets titled "A MaterialsInventory of Maricopa County [Arizona]" by the Arizona HighwayDepartment (AHD), now named the Arizona Department ofTransportation (ADOT), hereafter referred to as the 'Source'.Pit locations were represented by point symbols in the Sourcemap sheets. Points were digitized from the Source map sheets.Selected attribute data were collected from the Source pit dataand map sheets. In the Source introduction it states:> "The pit location maps show the location of all> pits bearing Materials Services serial numbers.> Other sources are not...
Distribution and quality of potential sources of aggregate infrastructure resources project area, Colorado-Wyoming
Crushed stone and sand and gravel are the main types of naturalaggregate used in the United States. Aggregate is used in nearlyall residential, commercial, and industrial building construction,and in most public works projects including roads and highways,bridges, railroad and light rail beds, airports, water and sewersystems, and tunnels. Much of the infrastructure built during the1950s and 1960s has deteriorated to a point that requires extensiverepair or replacement. All this construction requires enormousamounts of aggregate. In Colorado, for example, nearly 45 milliontons of aggregate, or about 12 tons per person, were producedduring 1994.
