Description:
Abstract:
This data set was updated in 2014 by the Wyoming State Geological Survey. Polygons were merged, description information completed, and geologic units converted to representations to retain unit colors and patterns. The geologic map was digitized by Green, G.N., and Drouillard, P.H. in 1994, from original scribe sheets used to prepare the published 1:500,000-scale Geologic Map of Wyoming (Love and Christiansen, 1985). Stable base contact prints of the scribe sheets were scanned on a Tektronix 4991 digital scanner. The scanner automatically converts the scanned image to an ASCII vector format. These vectors were transferred to a VAX minicomputer, where they were loaded into Arc/Info. The dataset includes both linear and polygon features, with attributes derived from the original 1985 map. Updated dataset is available for download or purchase through the WSGS, http://www.wsgs.wyo.gov/data/gis/ ; https://sales.wsgs.wyo.gov/catalog/index.php Original images (Map, Legend, and Sources): http://www.uwyo.edu/geolgeophys/about/geologic-map-wyoming.html. DIGITAL DATA INFORMATION: GEOLOGIC SYMBOLOGY (FGDCGeoAge font used for labeling Special Characters in SYMBOL field): Mz = Mesozoic Pz = Paleozoic K = Cretaceous ^ = Triassic IP = Pennsylvanian _ = Cambrian Y = Middle Proterozoic X = Early Proterozoic W = Late Archean V = Middle Archean U = Early Archean FOOTNOTES (fn): 1. Query indicates uncertainty of position of top of unit within the Pleistocene. 2. Age of upper parts of uppermost Miocene units is problematic. These parts have historically been assigned to the Pliocene. Successive reductions in radiometric age of the top of the Miocene in Europe to 7 Ma (Lambert, 1971) and to 5 Ma (Berggren, 1972) place a Pliocene age in question, although the top beds of the formations have not been dated. 3. Karlstrom and others (1983). 4. Divis (1976). 5. Houston and others (1968). 6. Snyder (1980). 7. McCallum (1968).
Purpose:
This geologic map was updated in order to satisfy printing and digital requests, as the map is no longer available in hard copy through the USGS.

WSGS update in 2014. Gregory N. Green, and Patricia H. Drouillard, 1994, digitized the Geologic Map of Wyoming. Original scribe sheets and negatives were from David Love, Anne Coe Christiansen. Pat Stamile of the USGS and Chris Arneson and Laisan Serebryakov of the University of Wyoming Water Resources Center provided digital review.

Process_Description:
The geologic map was digitized from scribe sheets used to prepare the published Geologic Map of Wyoming (Love and Christiansen, 1985), consequently at a 1:500,000 scale. Stable base contact prints of the scribe sheets were scannned on a Tektronix 4991 digital scanner. The scanner automatically converts the scanned image to an ASCII vector format. These vectors were transferred to a VAX minicomputer, where they were loaded into Arc/Info. The dataset includes both linear and polygon features, with attributes derived from the original 1985 map.
