Originator: Early, III, Drummond Publication_Date: 2002 Title: Geologic and aeromagnetic maps of the Fossil Ridge area and vicinity, Gunnison County, Colorado Geospatial_Data_Presentation_Form: vector digital data Series_Information: Series_Name: U.S. Geological Survey Geologic Investigations Series Issue_Identification: I-2738 Online_Linkage: http://pubs.usgs.gov/imap/i-2738/ Description: Abstract: This data set includes a GIS geologic map database of an Early Proterozoic metavolcanic and metasedimentary terrane extensively intruded by Early and Middle Proterozoic granitic plutons. Laramide to Tertiary deformation and intrusion of felsic plutons have created numerous small mineral deposits that are described in the tables and are shown on the figures in the accompanying text pamphlet. Also included in the pamphlet are numerous chemical analyses of igneous and meta- igneous bodies of all ages in tables and in summary geochemical diagrams. The text pamphlet also contains a detailed description of map units and discussions of the aeromagnetic survey, igneous and metmorphic rocks, and mineral deposits. The printed map sheet and browse graphic pdf file include the aeromagnetic map of the study area, as well as figures and photographs. Purpose: This GIS geologic map database is provided to facilitate the presentation and analysis of earth-science data for this region of Colorado. This digital map database may be displayed at any scale or projection. However, the geologic data in this coverage are not intended for use at a scale other than 1:30, 000. Supplemental useful data accompanying the database are extensive geochemical and mineral deposits data, as well as an aeromagnetic map.

Zech, C.G. Chase, Bruce Bartleson, C.G. Rosenlund, and Drummond Early III. Geochronology by Ed DeWitt and R.E. Zartman. Geophysics by R.A. Martin, Bob Kucks, and Ed DeWitt. The ArcInfo database was created by RedZone Software. ArcInfo database reviewed by Nancy Shock, who also prepared the ArcInfo files for importing into Illustrator. The Adobe Illustrator layout, which was used for the printed map and for the PDF browse graphic, was prepared by Gayle Dumonceaux. Metadata file prepared by F.C. Brunstein. Native_Data_Set_Environment: Data set was created using ESRI ArcInfo version 7 on a Unix platform Data_Quality_Information: Attribute_Accuracy: Attribute_Accuracy_Report: The linework was captured by hand digitizing from a hand-drawn 1:30,000-scale stable base map. Vector and polygon attributes were obtained from a compilation of field maps. The digital data have been visually checked and the geologic map has undergone technical review. Logical_Consistency_Report: This geology data set is a network coverage containing arcs and polygons. Each polygon has a coded attribute designating the mapped geologic unit. Faults and stratigraphic contacts are represented as arcs. When a fault is also a stratigraphic contact, only a single arc is present. Dangling arcs may be present (faults, dikes, etc.) Completeness_Report: These digital files are the geospatial files used to create the geologic map. Files for the text, references, tables (chemical analyses, geochronology), and other figures are not included in the database files but are included in the browse graphics and printed copies of the map and pamphlet. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: Users of this digital geologic map should respect the intentions of the original mappers and the limitations of the map. This geologic map is intended to be used at a scale of 1:30,000; it is not intended to be used at a more detailed scale.
