INTRODUCTION

The data on the enclosed diskette were used by the USGS for a mineral resource assessment of the GMUG National Forests and adjacent areas of southwestern Colorado (Bankey and others, in press). This data release is in four parts: A. description of mineralized areas; B. data files in various formats for viewing and plotting, or for importing into other applications (table 1); PDF images of an index map, mines and mineralized areas, a simplified geologic map, a claim activity map, and mine location maps by quadrangle (table 3); C. ArcExplorer (ArcExplorer Project [.aep] files are in the root directory) to display the data in "map" views and query the various datasets without requiring the user to purchase a GIS program such as Arc/Info1, ArcView1, or MapInfo (table 2); and D. metadata files for each dataset. File extensions are explained in table 1.

Methodology

In order to assess the mineral resource potential of the GMUG study area (figure 1, PartB\PDFimage\gmug_index.pdf), Wilson, Crane, and Woodard located mines and prospects (PartB\Data\mines.xls), and in combination with digital geologic maps, geochemistry, and geophysics, and advice from coworkers, Wilson and Spanski outlined 37 mineralized areas (figure 2, PartB\PDFimage\mnrlareas&mines.pdf; PartB\Data\...\mnrlarea.*). A mineralized area (MA) encloses a geographic area that is defined by the presence of mines, prospects, and/or mineralized occurrences that belong to one deposit-type or a group of genetically related deposit-
types in a distinct geologic setting. A MA may include an entire district or portions of several mining districts. Twenty-five of the areas are based on the occurrence of a single mineral deposit-type and eleven on multiple deposit-types.

Much of the mine and prospect data for the GMUG study area was extracted from site records for mines, prospects, and occurrences contained in U.S. Geological Survey (USGS) and U.S. Bureau of Mines (USBM) data files. A.B. Wilson, M.J. Crane, and M.D. Woodard (U.S. Geological Survey) verified as many of these data records as possible and added many more sites from information extracted from references and maps during the verification process. Locations of approximately 1,300 sites (solid red squares on fig. 2, PartB\PDFimage\mnrlareas&mines.pdf; figs. 5-16, PartB\PDFimage\Mines by Quadrangle\...) are believed to be accurate to within about 1/2 mi (750 m, or 2,500 ft) of their actual ground position. About 1,000 sites could not be verified from references but could be generally located using data (such as Township and Range or descriptive information) in the database records: these sites (red diamonds on figures 2; 5-16) are believed to be accurate to within about 1 mi (2 km, 5,000 ft). A few sites plot in one quadrangle but list a different quadrangle in the database–these are shown as green diamonds and labeled "wrong quad" in the symbol field. Placers are indicated by orange (reasonably located) or yellow (location not unverified) crosses, but none of the placer records was checked for this project. There was insufficient location data to plot about 200 of the sites in the MRDS and MAS/MILS databases: these sites are included in mines.* files but are not shown on figures 2 and 5-16.

Table 1. Data files showing file names, formats, and projections.

[Three character file extensions throughout this report are as follows: .e00, Arc/Info export file; .shp, ArcView shape file; .tab, MapInfo table file; .xls, Microsoft Excel spreadsheet; .tif, tagged image file, raster based, for use in many different programs; tfw, a file to accurately georeference a .tif image; .met, metadata in text format; .aep, ArcExplorer Project file; pdf, Adobe Acrobat Reader portable document file; *, refers to any extension. UTM13, Universal Transverse Mercator Projection, zone 13; lcc108, Lambert Conformal Conic projection, 108o West Longitude central meridian.]
