A GEOGRAPHIC INFORMATION SYSTEM FOR THE HUMBOLDT PEAK QUADRANGLE, EAST HUMBOLDT RANGE METAMORPHIC CORE COMPLEX, ELKO COUNTY, NEVADA
The presentation of this data in a geographic information system simplifies its manipulation and communication. The architecture of the GIS is built on a topographic base presented either as a digitized topographic contour map or a hillshade on the DEM. Overlying layers include the bedrock geology, metamorphic assemblages and PT determinations, radiometric age date localities, and structural orientation data including foliations, lineations, shear sense indicators, and fold hingelines and axial planes. Compilation of the orientation data in digital format facilitates domain analysis and data extraction for stereographic orientation analysis. Supplemental information includes a three-dimensional representation of the geology extruded on topography, the structural cross-sections, and remote sensing data. These tools will facilitate publication, dissemination, and future analysis of the data from the East Humboldt Range as well as providing a template for production of geographic information systems for adjacent areas. In addition, the flexibility of this approach allows for the accumulation of new data in the future.
