A variety of sources of minerals information were consulted in compiling a digital map of mineral resource areas for metallic minerals in the Yellowstone River Basin. Source scales varied, but were no smaller than 1:500,000. The data are intended for river-basin level assessment and general analysis and are not suitable for site-specific analyses. These data were prepared for use in describing the environmental setting of the Yellowstone River Basin (YRB) study-unit investigation, part of the U.S. Geological Survey's National Water-Quality Assessment (NAWQA) Program. The data were used in planning the study by contributing to an initial stratification of the river basin into environmental subunits. Source scales varied, but were no smaller than 1:500,000. The data are intended for river-basin level assessment and general analysis and are not suitable for site-specific analyses. Mineral resource areas are defined as those areas with a high likelihood of containing occurrences of valuable mineral deposits. A variety of sources of minerals information were consulted in compiling a digital map of mineral resource areas for metallic minerals in the Yellowstone River Basin. The data set was compiled using a set of materials that represent a general knowledge of metallic mineral deposits in the YRB that is current as of 1996.

Windows_NT, 4.0, Intel ARC/INFO version 8.0.2 Polygon feature attribute values were inspected and found to be consistently coded as described in the Entity and Attribute Information. Polygon topology present. No dangling nodes are present. Every polygon is closed and has a label point. The LABELERRORS algorithm reported no label errors. The data set is not a complete compilation of all mineral resource areas in the YRB. Many other small deposits exist. The subject data represent the areas of sufficient size or importance to warrant consideration in the stratification of the river basin for purposes of the NAWQA study-unit investigation. Cartographic generalization, particularly for the 1:500,000-scale source materials, is believed to have introduced more horizontal inaccuracy than the digitization procedure. Estimated horizontal accuracy of the linear features is 150 meters. Bayley, R.W., Proctor, P.D., and Condie, K.C. 1973 map Professional Paper 793 Washington, D.C.

Source maps were scanned at 300 dpi on a desktop color scanner, using 8-bit graphics. Scanned images were rotated as needed and saved as full-resolution TIFF files. Georeferencing of linework from scanned images utilized grid tick-marks or township corners shown in the scanned image data. The CLEAN algorithm was not used; dangling node errors were corrected in heads-up mode. Editing tolerances were as follows: > Tolerance Value > --------------- --------------- > Node Snap 10 to 500 > Weed 5 to 10 > Grain 25 to 100 Digitized linework was processed using the SPLINE algorithm.

MINERAL - Code distinguishing uranium resource areas from other mineral areas. Explanation of codes follows: > MINERAL Explanation > U Uranium resource area. > O Other metallic mineral resource area. LABFLAG - Logical flag to assist in labeling polygons. If LABFLAG eq 'Y' then polygon was labeled with value from NAME column. ESU - Code used in defining environmental subunits for YRB NAWQA study. The environmental setting analysis developed a set of 18 environmental subunits, corresponding to relatively homogeneous settings identified by combinations of six thematic variables: ecoregion, geologic group, land use/cover, coal- mining areas, metallic mineral resource areas, and oil fields. As one of the six thematic variables, the subject data for mineral resource areas was used to assign areas of the YRB to one of three categories: > ESU Assignment > 1 Metallic mineral resource area, other than uranium > 2 Uranium resource area > 0 Not in any metallic mineral resource area none U.S. Geological Survey Ask USGS - Water Webserver Team mailing
