Description:
Abstract:
In 2014, the dikes data was updated by the WSGS. The dikes were digitized in 1994 from the original scribe sheets that were used to prepare the published 1:500,000-scale Geologic Map of Wyoming (Love and Christiansen, 1985).
Purpose:
This dataset was updated in order to satisfy printing and digital requests, as the map is no longer available in hard copy through the USGS.

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.

Overview_Description:
Entity_and_Attribute_Overview:
Faults and dikes are accompanied with decorations for cartographic purposes. The DECO database is an attributed vector graphic overlay of the decoration coverage. This dataset contains the teeth of thrust faults, shear zones, bars and balls, impact structure, diatremes, and ARC/INFO annotation. DIKES is the attributed vector file of the single line outcrops. Dikes at a scale of 1:500,000 are best represented by a thin single line and consequently have no area. Line Types and Attributes
